Major Upgrade of the HKU Campus Network Infrastructure in Progress

Vision of a Digital University at HKU

With the rapid and great advancement of Information Technology (IT) in recent years, one can envision that wide-spread use of IT by our students and staff for their learning, teaching, research and administrative activities will be an inevitable development.  We are expecting in the next few years that an increasing number of our staff and students will be relying on the use of computers and access to the Campus Network and Internet resources in their teaching and learning, and a "Digital University" will emerge on the University of Hong Kong (HKU) campus by the beginning of the new century.

Major Upgrade of the University Campus Network Infrastructure

In moving the University of Hong Kong towards a Digital University in Year 2000, it is important for us to upgrade our Campus Network Infrastructure with substantial increases in speed and capacity so that our staff and students can have the support needed in using the latest technologies to facilitate their teaching activities and academic studies.

We are very pleased to inform our users that with the support of the University, we have been embarking on a major development in upgrading the Campus Network since summer of this year.  The development project is divided into three phases to accomplish the following goals:

Phase I -   to extend our Campus Network to places where students spend most of their studying time;

Phase II -  to overhaul the existing Campus Network Infrastructure for supporting 100 Mbps network connections to desktops of all staff and to implement a fast ATM network backbone for the University's major campuses, namely the Main Campus, the Sassoon Road premises, the Queen Mary Hospital (QMH) complex and the Prince Philip Dental
(PPDH) Hospital; and

Phase III - to build a "Network-Access-Everywhere" environment to allow students roaming connectivity to the HKU Campus Network and Internet throughout the University campus.

Phase I Development - more easy-to-access network facilities for students

Hall network and dial-up access improvement

This phase of development is close to its scheduled completion.  By the end of this year, each resident in student halls will be provided with a network connection point in his room for access to the University Campus Network and Internet resources.  In order to facilitate students who are not hall residents to have improved access to the network resources from home, Computer Centre has also installed 144 more dial-up lines which are of the x2-56Kbps standard in October.  Please refer to separate articles for more information on the hall network and the added HKUPPP dial-up facilities.

HARNET upgrade

In parallel with the work on the HKU campus, Computer Centre has been working closely with the JUCC (Joint Universities Computer Centre) on a major upgrade of HARNET (Hong Kong Academic and Research Network) and its Internet gateway connection which is supported by a grant from UGC.  The HARNET upgrade project is being implemented in 3 steps :

(a) adding 1.5Mbps HARNET-Internet bandwidth as an interim measure to improve the slow Internet access from HARNET institutions through NetPlus of Hong Kong Telecom,

(b) upgrading the inter-institution network links of HARNET from 1.5Mbps DDS links to 10Mbps ATM links, and

(c) upgrading the HARNET-Internet IPLC (International Private Leased Circuit) from 2Mbps to 6Mbps and providing an additional link of 1.3Mbps guaranteed bandwidth from HARNET to NetPlus for Internet connectivity.

The first 2 steps of the HARNET upgrade had been completed at the end of October and in the first week of December, respectively.  We are expecting that the entire upgrade will be completed before the end of 1997 according to the schedule.
According to JUCC's plan, the HARNET-Internet gateway connection will be further upgraded to 12Mbps in year 1998-99 and hopefully to T3 speed (45Mbps) in year 1999-2000.

With the completion of the HARNET upgrade and the Phase I upgrade of the HKU Campus Network by the end of 1997, our staff and students should then find Internet access from the campus to be much improved.

Phase II Development - an overhaul of the existing network

This phase of development is to modernize our University Campus Network Infrastructure with state-of-the-art technologies so that it can support the sophisticated Digital University applications to be developed and deployed
for teaching, learning, research and administration in the next decade.  In this phase of development, three projects are to be implemented for the purposes of :

With the completion of this phase of development, we shall have a modernized high-speed network for supporting the use of advanced Information Technology by teachers, students and researchers in their teaching, learning, research and academic collaboration, and by the administrators to re-engineer the University's administrative processes for improved efficiency.

Phase III Development - building a "Network-Access-Everywhere" environment

This phase of development is to establish a "Network-Access-Everywhere" environment in the University.  The project is to install wide-spread network access points in all departments at a level of one network point for every 4 fte (full-time equivalent) students of the departments, and in other places of student activities such as the Libraries, Computer Centre and student society offices at a level of one network point for every 12 students.

In the next few years, we shall see that the mode of teaching and learning at the University will shift to rely more on regular use of PCs and access to the Campus Network and Internet.  Noting that the University is in the process of formulating means to encourage and promote academic staff to use modern learning technologies in their teaching activities, the demand of access to networked PCs by students will certainly be ever increasing.  When this phase of development is completed, our students will then have more convenient and effective access to the network resources set up by their teachers, from the Libraries and the Internet.

Combined implementation of Phase II and III Development

It was Computer Centre's original plan to implement the projects of Phase II in 1998 and complete those of Phase III in 1999.  Noting that the University has embarked on the "Laptop Computer Initiative" which will enable all new undergraduate students enrolled in the 1998-99 academic year to own their laptop computers, it has become more desirable if the Phase III development, i.e. the "Network-Access-Everywhere" campus, could be realized sooner.  Therefore, Computer Centre has taken up the challenge to revise the project plan to implement both Phase II and Phase III at the same time and complete them within 1998.

Computer Centre is now in the process of consolidating the requirements from all departments for the design and layout of the network points, and will soon work with the Estates Office and departments on the actual implementation.  We hope that with concerted efforts from all parties concerned, a modernized and sophisticated IT infrastructure will evolve at HKU in a year's time.

 A Student User Survey of Computer Services

From the information collected through the last user survey on the Centre's computing services conducted in January of 1997, we were able to get some very useful information from our users in terms of their computer needs, how they rate their satisfaction level of our services and suggestions for improvement of the computer services.

Some of the suggestions for improvement have already been implemented or are in the process of being developed, for example, the network is being upgraded, more PPP dial-up lines and faster modems have been installed, more training courses are delivered and the self-taught training presentations have been enhanced.

The last survey was done through paper questionnaires sent to all Term-of-Service I staff and also through the web for students. However, only a small number of students were aware of that survey.

We are now conducting a new survey to obtain more input from our students about the Centre's computing services. The information and feedback from this survey will help us to have a more comprehensive picture of the computing needs of our student users so we can provide better services and facilities to support the teaching, learning and research activities. We look forward to the students' participation in the forthcoming computing facilities and services survey.

Starting date: Monday, January 5, 1998
Closing Date: Sunday, January 18, 1998

New x2/56Kbps Dial-Up Modems Available

We are pleased to announce that Computer Centre now provides the x2/56Kbps dial-up service for home access to the HKU Campus Network as a major improvement of Centre's dial-up facilities. By the end of October, a total of 144 x2/56Kbps modem lines have been installed. (Among these lines, 48 and 96 lines were put into service on September 30 and October 31, 1997 respectively.)

What is x2 standard?

x2/56Kbps is a new modem standard designed by the U.S. Robotics Corporation. Although the x2/56Kbps technology can, in theory, support connection speeds of up to 56Kbps, the performance of a connection relies highly on the quality of the telephone line. Users in different districts in Hong Kong may find their connection speeds quite different. Connections using x2/56Kbps modems at both ends normally can achieve speeds of higher than 40Kbps. Good connections may achieve better performance with speeds of higher than 50Kbps.

There are currently two 56Kbps modem standards: x2 and K56Flex. Users of K56Flex modems or other modems dialing to the HKUPPP 56K Server can only achieve up to the data rate of 33.6Kbps or less. To enjoy higher than 33.6Kbps connections, you need to use a x2/56Kbps modem.

Apart from the speed improvement, the new HKUPPP 56K Servers use leased channelized-T1 circuits, each of which supports 24 56Kbps PPP dial-up connections.  This provides more stable connections and there will be fewer chances of line dropping due to cross-talk and noise problems which are experienced with the individual analogue dial-up lines. Therefore, we would encourage all our users to choose to use these new lines if possible since they can benefit from the new modem pool to have better quality connections even when non-x2 modems are used.

A new HKUPPP dial-up package, tailored for use with the the x2/56K HKUPPP modem pool, is being developed and will be available very soon. For the time being, you can follow the instructions provided on the web URL: to configure manually the existing HKUPPP package installed on your PC for dial-up connection to the new modems.

Mondays to Fridays: 09:00-12:30,14:00-17:30
Saturdays: 09:00-12:30
Sundays and Public Holidays: closed.



If you want to know the name of the computer officer serving at the Help Desk for that day, browse in the Help Desk officers roster 

You will be asked for your staff/student number because we have to record all Help Desk problems for problem analysis and development of FAQ's (frequently asked questions) later.  The problem logging also helps us in the identification of user needs of our services and of areas for improvement.  

The Help Desk officer will then try to understand your problem and usually will provide you with a solution right away.  If the officer cannot solve your problem, it is then referred to a subject officer who is more knowledgeable in that particular area.   

(Tel: 2859 2480) 

You can also call the Help Desk during office hours.  If the phone at the RR-109 site is busy, your call will be automatically switched to the Old Library site. You may have to try again if both phones are busy. 


Trivial problems are usually solved within 10 minutes while difficult problems (referred to subject officers) will take no more than 2 weeks.   

The problems log and statistics will be presented and discussed at a user service meeting once a month. At this meeting, areas which need further FAQ's or other documentation to be developed will be identified. User training courses will also be developed or sourced from a course vendor. We try to make every effort to make it easier for users to use the Centre's facilities and services. 

If you have any suggestions or comments about the Help Desk, please send an e-mail to our Help Desk Manager.  You can be sure that your suggestions will receive due attention at our monthly user service review meetings for problem resolution or service improvement.

Upgrading the Campus Network to ATM

In October 1996, Computer Centre has successfully completed the pilot project of deployment of ATM backbone network connecting the Run Run Shaw Building, the Old Library Building, and the Meng Wah Complex.  (See article on ATM and Virtual LAN at HKU in Computer News #65).

This year we have focused on extending the ATM (155 Mbps to 622 Mbps) backbone network to the other buildings in the main campus and gradually replacing the FDDI (100 Mbps) backbone network, replacing T1 connections to remote campuses using public ATM network, and deploying the ATM VLAN (Virtual Local Area Network) technology to connect dispersed locations. By January 1998, the ATM backbone network of the University's Campus Network will be in place.  The progress so far is as follows:

Surfing the Web with Microsoft Internet Explorer (MSIE v.3) in PC Laboratories

The Microsoft Internet Explorer (MSIE) is a commonly known web browser other than the Netscape web browsers.  MSIE v.3.0 is provided in our PC laboratories running Windows 3.1, Chinese Windows 3.1 and Windows NT Workstation.

MSIE 3.0 has similar capabilities as the Netscape Gold 3.0, namely, the web browser, an HTML editor, mail program and news reader. When you start MSIE 3.0, the browser window will be launched with the following menu and toolbar layout:

There is an extensive Help facility to assist you to use the supported functions. Some of the commonly used functions of MSIE 3.0 will be briefly described below. For more details, please refer to the Help facility.

The Browser

Procedure to use MSIE in the Windows NT Workstation Laboratory (Room RR-101)

  1. Login a PC running Windows NT Workstation.
  2. Double click on the MSIE icon on the Windows NT Workstation desktop.

Procedure to use MSIE in other PC Laboratories

  1. Start the English or Chinese version of Windows 3.1 on a PC.
  2. Double click on the MSIE icon in the "Microsoft Internet Explorer" program group.

The menu and toolbar items in the MSIE 3.0 browser window are very similar to those in Netscape 3.0. Some variations do exist.

Clicking on the Font button on the toolbar will allow you to increase or decrease the size of the fonts appearing in the current browser window.

The list of Favorites  is equivalent to the Bookmarks in Netscape. You can add a bookmark of a frequently accessed website to the list of favorites or organise the favorites by clicking on the Favourite button.

To print a file, you can use either the Print button on the toolbar or by clicking the menu File -> Print.  You can set up the layout and format of your printed page with the menu Print -> Setup, but there is no Print Preview function in MSIE 3.0.

In the Windows NT Workstation laboratory (Room RR-101), we have installed a traditional Chinese font in each of the PCs to facilitate your reading of Chinese web pages with the English version of Windows NT Workstation provided. For the other PC laboratories, you can read Chinese web pages by first selecting the Chinese Windows 3.1 from the HKUMENU.

The HTML Editor

You can edit the HTML codes of a web page by first bringing the page into the browser and then clicking the menu View -> Source.  An HTML editor window will be opened where you can make changes to the HTML codes and save the modified web page.  To view the changes, simply click on the Refresh button on the toolbar. Unlike the Netscape Gold 3.0 editor, you have to work directly with HTML codes in the MSIE 3.0 editor and hence knowing HTML coding is a prerequisite.

Read Mail/News

To read mail or news, click on the Mail button on the toolbar, and then select Read Mail or Read News or use the menu Go. You will then be prompted for the information to configure your mail server and your news server.

For the mail server, you will be asked to specify your email address, user account name and password. The setting for the incoming mail server should be set to the hostname of the system on which your email account is created, e.g. or  For the setting for the outgoing mail server, you can simply set it to

For the news server, input the name

Note: As the MSIE v.4 has recently been released, its installation in our PC laboratories is being studied.

Netscape Communicator 4.0 Available

Netscape Communicator v4.03, hereinafter called the Communicator 4,  is the latest version of the Netscape suite of programs for Internet Communications. Communicator 4 is currently installed on the Pentium PCs running Windows NT Workstation in room RR-101. You can also download the software to your own computer from a mirror site in Hong Kong

Communicator 4 has many new features and improvements over its previous version, Netscape Gold 3.0.  This article will highlight the new and enhanced features in Communicator 4.
The Communicator 4 provides an extensive Help facility to help you use any component of the software.

Components of the Communicator suite

The heart of Communicator 4 is in the Communicator menu. When it is clicked, all the components of the Communicator suite will be displayed in the pull-down menu.  Navigator, Mailbox, Discussion Groups, and Composer are enhanced components which were already available in Netscape Gold 3.0. New components of Communicator 4 are Conference and Netcaster for the Standard edition.  The Professional edition provides the Calendar, IBM Host-On-Demand and Auto Admin.

Setting Preferences

The old menu "Options" for setting preferences in the previous versions is now placed under the menu "Edit", then "Preferences...".  Double clicking a folded-up category (with a "+" sign in front) will unfold all the levels hidden under that category. Double clicking an unfolded category (with a "-" sign in front) will fold up all the levels under that category. Settings of cache, proxies and disk space are all grouped under the category "Advanced".

This is the browser component of Communicator 4. Clicking on the Navigator component will start a new browser window.

The Communicator screen looks quite similar to the Netscape Gold Navigator screen.  For accessing the Netscape home site, click on the big "N" icon at the far right end of the menu bar.

The Communicator supports the drag and drop technology in all of its components. You can now create your own personal toolbar by dragging the page proxy icon (on the right-hand side of Bookmarks) and dropping it on the personal toolbar.  This makes access to the most frequently visited places even more convenient.  Search on the Internet is made more direct by placing the icons Search and Guide on the browser toolbar.

Printing of any web page can be done by first selecting menu File -> Print Preview to determine the page number of the page you want to print, and then selecting the menu File -> Print and specify the page number.   You can now read a web page, mail, news article or a Netcaster channel off-line to save connection cost by selecting the menu File -> Go Offline.

Clicking the menu Security will display the security advisor which gives you comprehensive information on all Communicator security features and how they can be used.

Messenger Mailbox

This is the Mail component of Communicator 4. Clicking on the Mailbox component will start a new mail window.

You have to configure your Communicator first with all the information about your mail server and your email address by selecting the menu Edit -> Preferences -> Mail & Groups -> Mail Server.

Fill in your host computer account name in the field for "Mail server user name" and fill in in the field for "Outgoing mail (SMTP) server".  For the field "Incoming mail server", you should fill in the name of the host computer on which your e-mail account is created e.g.

For the "Mail Server Type", select POP3 and not IMAP:

You can consult the Help menu for the settings of the other parameters.
 The Mail Window looks like the following:

When the mail window is open, clicking on a mail header once will open the mail in the bottom half of the screen. Clicking on a mail header twice will open it in a full screen.  To return to see the mail headers, click on the green "return" icon  at the far right end of the window.

You can send voice mail by first recording a voice message (a .wav file) and then send the voice file in an ordinary mail.  The voice mail function is located in the Communicator menu of the Conference component, and the documentation for it can be found in the Help menu within that component.

Collabra Discussion Groups
This is the News component of Communicator 4. Clicking on the Collabra Discussions will start a new Message Centre window displaying both the mailboxes and newsgroups.

You have to configure your Communicator first with the name of your news server by selecting the menu Edit -> Preferences -> Mail & Groups -> Groups Server. Set the value of the field "Discussion groups (news) server" to News articles are placed in a folder under the default directory "C:\Program Files\Netscape\Users\username\news\".

The Message Centre Window looks like the following:

Clicking on a newsgroup will launch another window just like the mail window described above. You can view the news articles in a half screen or a full screen.  To return to the Message Centre, just click on the green "return" icon  at the far right side of the screen.

Computer Centre maintains a newsgroup called which is a user forum on computer usage in HKU where users can exchange tips and help each other out. You are encouraged to use the newsgroup for testing purposes until you are familiar with the procedures of posting news.

Please consult the Help menu on how to search and subscribe to a newsgroup, how to post a new topic or respond to a discussion, and all about security issues such as certificates and electronic signatures, encrypting and decrypting messages.

Web Page Composer

This is the Editor component of Communicator 4. Clicking on the Composer component will start a new editor window for writing web pages to be placed on a server. You can then select a new file or an existing file to edit, which will give you another editor window.

The Composer Window looks like the following:


If you are a web page developer, you will like the enhancements in the Composer. Under the Format menu, you will find that you can format your document in any font, size, style, color, even blinking text.

Image handling is much easier in the Composer.  You can now import objects created by other Microsoft software which support the OLE feature (e.g. an Excel table) using the copy and paste function. You can capture a picture from screen (with the Print Screen keyboard button) and insert the picture directly in a web page as the Composer will convert the image into the right format (.gif or .jpg) for you.  The size of an image can also be easily adjusted by pulling on the rim.

The most welcomed new feature for web page authors is probably the spell-checker.  You can find that under the Tools menu or click on the Spelling button on the tool bar.


This is the new conferencing component of the Communicator. Clicking on the Conference component will start a new conference window which allows you to participate in real-time online chats with others on the network.

You have to configure your Conference component first with all the information about your peers in a conference.  In the Conference window, click on the menu SpeedDial  -> Speed Dial 1 (or any menu entry) -> Edit. The following window will appear.

The field "Name" is for ease of identification. The field "Email" and "DLS server" can be filled in if you are sure that your peer, Mabel Chau in the above example, has registered her email address in the specified DLS (Dynamic Lookup Service) server on the Internet.  Otherwise, you need to input the IP address of your peer's computer in the field "Direct address". (The IP address is in the form of 4 numbers separated by periods, like, which identifies a computer on the Internet.)

To start a conference, input your peer's name and IP address (or Email address if s/he has registered in a given DLS server) in the field "Email address" and then click on the Dial button.

It is fun to send and receive voice mail.  Consult the Help menu for details on how to send a voice mail, how to start an audio conference, collaborate on the whiteboard and chat tools and finally how to save the session logs.
Note: You must pre-arrange a time for conferencing with a partner.  In order to place and receive calls, Netscape Conference must be up and running on the computers of both partners.  Also, in order to navigate on the web collaboratively, control of the navigation must be passed explicitly between the partners.


The Netcaster (version 1.0) is a new feature of Communicator 4.  It enables you to subscribe to channels (web sites) and schedule automatic delivery/updating of information from the channels instead of manually searching all over the Internet and saving the web pages and images individually.  You can then read the information at your leisure while you are off-line.

A channel usually carries focused information on a specific topic of interest, and the content is pushed onto your desktop automatically, therefore this is also called "push content delivery".

Note: You have to be connected to Internet in order to update your channels.

Other Components (for Professional edition only)

The Calendar allows you to schedule time tables either on your stand-alone PC or on a server in a timetable shared with others (in which case, a Netscape calendar server is needed).

The IBM Host On-Demand is not applicable in the HKU environment as we do not have IBM Mainframe hosts which require the use of TN3270 terminals.

The AutoAdmin is designed to be used by administrators only.  Web administrators can consult the Help menu on the use of this feature.

PGI High Performance Fortran (HPF) compiler Version 2.2 Available on HKUSUB

We are pleased to announce that the Portland Group (PGI)'s High Performance Fortran (HPF) compiler version 2.2 is available on hkusub.

HPF is a new standard programming language for supporting parallel programming. The advantage of using parallel programming over the traditional serial programming is to reduce the run time of a program by distributing its loads to more than one processor. There are experienced support staff in Computer Centre who can help you in using this parallel programming language. So, users are advised to consult the HPF support staff of Computer Centre before they start to use the language. 

What is HPF ?

High Performance Fortran (HPF) is a set of extensions to the Fortran 90 language. It allows systems of interconnected processors to be easily programmed:

It has been said that the comparsion between explicit message-passing programs and those developed with HPF is similar to the comparsion between assembler programs and programs developed with high level languages. This analogy is appropriate as HPF programs are simple to write but will not be as efficient as an explicit message-passing equivalent.

The HPF directives specify the location (or layout) of the data and the parallel array syntax, intrinsic functions, HPF library calls and HPF FORALL or INDEPENDENT DO loops specify the parallelism.

In theory, a Fortran 90 program can be passed unaltered through an HPF compiler and will be parallelised using the system defaults. This will not be the most effective way to parallelise code but in some cases will increase the speed significantly.

How to use the compiler

The compiler is available on hkusub, so you have to compile your programs there. However, the executable files it produces can be run on hkusua also.

To compile a HPF program, use the following command :

pghpf -Msmp -Mfreeform program.hpf -o program.exe
npghpf program.hpf -o program.exe
Note: npghpf has the following option as default.

To run a program, use the following command :

program.exe -pghpf -np 4 -heapz 8m

Where -np 4 means using 4 processors.

There are 8 and 12 processors in hkusub and hkusua respectively, so users may use 1 to 8 processors in hkusub or 1 to 12 processors in hkusua.

Click here for the user manual of the compiler. 

A sample HPF program

Following is a sample program taken from the Fortran 90 standard manual, pp 296-298.  The code has been modified to make it a main program instead of a subroutine. The algorithm used is the Ising model. HPF directive has been added in the code so that the HPF compiler would know how to parallelize the program.

The sample program is for a 3-D Monte Carlo simulation of state transition. Each gridpoint is a logical variable whose value can be interpreted as spin-up or spin-down. The transition between states is governed by a local probabilistic process where all points change state at the same time. Each spin either flips to the opposite state or not depending on the state of its six nearest neighbours. Gridpoints on the edge of the cube are defined by cubic periodicity - in other words the grid is taken to be replicated in all dimensions in space.

This sample program has been tested on hkusub. Following is a comparsion of the elaspe running time using different number of processors.

Elapse time of running HPF Ising program on hkusub

This is the program code which will perform the desired transitions.

!The following directive tells HPF compiler the relative position of elements of
!"ising", "flips", "ones", "threshold" with respect to "count".
!HPF$ ALIGN WITH count :: ising, flips, ones, threshold

       p = (/ 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 /)

       iterations  = 100
       ising = RAND(n) .LE. 0.5

       DO i = 1,iterations
        ones = 0
        WHERE (ising) ones = 1
        count = CSHIFT(ones, -1, 1) + CSHIFT(ones, 1, 1) &
              + CSHIFT(ones, -1, 2) + CSHIFT(ones, 1, 2) &
              + CSHIFT(ones, -1, 3) + CSHIFT(ones, 1, 3)

        WHERE (.NOT.ising) count = 6 - count
        threshold = 1.0
        WHERE (count == 4) threshold = p(4)
        WHERE (count == 5) threshold = p(5)
        WHERE (count == 6) threshold = p(6)
        flips = RAND(n) .LE. threshold
        WHERE (flips) ising = .NOT. ising

Fujitsu Fortran 90 Compiler Available on HKUSUB


We are pleased to announce that the Fujitsu Fortran 90 compiler version 2.2 is available on hkusub as an alternative to the SUN Fortran 90 compiler.

This compiler compiles Fortran 66, Fortran 77 and Fortran 90 programs. In addition, it takes advantage of the multi-processor capability of hkusua and hkusub and parallelizes the execution of programs. Programs compiled by this new compiler would run much faster than the ones compiled by traditional compilers.

This compiler has many features. There are experienced support staff at Computer Centre who can help you use this compiler. So, users are advised to consult the HPF support staff of Computer Centre before they start to use this compiler.

Optimization Feature

To maximize the processing speed of your application, Fujitsu Fortran offers a wide range of finely tuned optimization features:

Basic optimization

Program reconstruction optimization

Procedure optimization

Multi-processor optimization


Additional features include:


Fujitsu Fortran complies with the following standards:

The compiler allows you to select Fortran 90, Fortran 77, or Fortran 66 options. You also get Fortran 90 obsolescence checking and the ability to link object code from other vendors' compilers (as long as the other code does not include I/O or intrinsic procedures). Fujitsu Fortran provides a data migration path from S360 to IEEE floating point formats.

How to use the compiler

The compiler is available on hkusub only, so you have to compile your programs there. But the executable files it produces can be run on hkusua as well.

To compile a Fortran 90 program, use the following command :

frt -Kfast,gs,V8PLUS,GREG,eval,parallel,ocl,auto,reduction -Et -x- program.f -o program.exe
nfrt program.f -o program.exe
Note: nfrt has the following option as default.

To run a program, use the following command :

# This sets the number of processors, [np],  on which your program will be run.
setenv PARALLEL [np]
# This runs the program in [np] processors.

There are 8 and 12 processors in hkusub and hkusua respectively, so users may use 1 to 8 processors in hkusub and 1 to 12 processors in hkusua.

The user manual of this compiler is in the text file /data4/sunf90/fj/FSUNf90/help/C/F90.user of hkusub. Chapter 7 explains in detail how to use the automatic parallelization feature of this compiler.

Networking the HKU Residential Halls

Since early September of this year, the project for networking the student residential halls has been well under way, and is heading towards the targeted completion date of 31 December, 1997.

A total of 2,732 network points were installed across 9 residential halls. Intensive work in infrastructure has been carried out in these 9 halls by 3 contractors. The completion of the project will result in an autodetecting 10/100 Mbps network port installed for every hall resident, and a PABX telephone system in every hall, bringing telephone service to each resident. Hall residents can therefore anticipate better communication facilities, in both data and voice.

Of the 9 residential halls, seven are remotely situated, and will be linked up via HK Telecom's Framelink service, which is in turn integrated with the HK Telecom's public ATM network, to the ATM network backbone of the HKU Campus Network. The two halls on the Main Campus, i.e. Swire Hall and Simon K. Y. Lee Hall, will be directly connected to the University's Campus Network. The following table summarises the connection speeds of the lines extending to the halls:


Speed of data line to CC

University Hall 128kbps
Weilun Hall 

Lee Hysan Hall 

R. C. Lee Hall 

Madam S. H. Ho Hall Residence for Medical Students

together linked via T1 (1.544Mbps) line
Ricci Hall 128kbps
St. Johnís College (Undergraduate wings) 128kbps
St. Johnís College (Postgraduate wing) 128kbps
Simon K. Y. Lee Hall Directly connected to the main campus ATM network
Swire Hall Directly connected to the main campus ATM network

The completion dates of the connection of the Halls will vary, and will be in December 1997.

Instructions on how to connect from the Hall-Network to the Campus Network (and hence to the Internet) is given in detail on the Hall-Network web page. Hall residents can follow the instructions accordingly to network their PCs in the Halls.

Internet Access from a Classroom

Centrally administered classrooms (classrooms for short) have been networked for some time. Users can use computers in networked classrooms to facilitate teaching, training, demonstration, etc. As Internet access (e.g. WWW browsing) becomes more and more popular, the increase of access to Internet from classrooms can be foreseen.

The installation of the ATM (asynchronous transfer mode) backbone network in October 1997 makes the connection of a computer in a classroom in the Main Campus to Internet or to host computers on the Campus Network (e.g.,,,,, etc.) a much easier task.

In the past, users had to set the TCP/IP parameters of their computers according to a set of pre-defined values for the different classrooms. Many users using the classrooms find such a set-up process rather inconvenient.

Computer Centre exploits the ATM technology to improve this situation. As an initial step, a single ATM VLAN (Virtual Local Area Network) is set up for the classrooms in the Main Campus.  Although the classrooms are located at various different sites, they are now managed as if they are in the same LAN.

Secondly, the VLAN enables us to deploy a DHCP (Dynamic Host Configuration Protocol) server for assigning a unique IP address and the related parameters to a user's computer connecting to the Campus Network from a classroom. For proper functioning of a computer, besides getting its own IP address, it needs to know the IP address of a Domain Name Server (DNS) which provides the service of mapping the name of a host, e.g., to the host's IP address.  The DHCP server that we are employing can also assign the IP address of a DNS to the user's computer.

With implementation of the above mentioned facilities, the configuration procedures for a computer running Windows 95 and Macintosh become simplified.  For detailed procedures, please click here . (The procedures also include instructions for configuring a computer running other operating systems.)

There will be demostration sessions on how to set up a PC in a networked classroom for Internet access. All interested users are welcome.  Please refer to our training news for schedules of the desmonstrations.

RAID Technology for Central LAN File-Servers

Computer Centre has recently employed the RAID technology for the centrally managed LAN file-servers so as to increase the reliability and availability of the heavily used file-servers.

RAID stands for Redundant Array of Inexpensive Disks. It is a technology that offers data protection through the storage of redundant information across an array of disks. Even if one of the RAID disks fails, the LAN file-server employing RAID disks will be able to run without interruption because data integrity is guaranteed by other non-faulty disks. The faulty disk can be removed from the RAID cabinet and replaced with a new disk, without shutting down the non-faulty disks or the LAN file-server.

The RAID software and hardware sub-system will regenerate the data on the new disk within a few hours with the redundant information stored across the RAID disks. As long as a second disk does not fail during the restoring process, the RAID disks will function as if no failure had occurred. Since many cases of LAN file-server crashes are due to disk failures and large volumes of data of LAN file-servers take many hours to restore from backup tapes, the down time of our LAN file-servers could be reduced with the introduction of the use of RAID disks.

The following LAN file-servers have been installed with RAID disks as of November 1997:

  • HKUPC1
serving the PC Laboratories in Run Run Shaw Building, Knowles Building, and Tsui Long Sing Amenities Centre
  • HKURM1
serving departments in the Runme Shaw Building
  • HKUKK2
serving departments in the K. K. Leung Building
  • HKUHW1
serving departments in the Haking Wong Building
  • HKUQP1
serving departments in the Queen Mary Hospital
