IBM 9076 Scalable POWERparallel System Ready for Initial Service

We are pleased to announce that our IBM 9076 SP1 system (with a theoretical peak performance of 1 GFLOPS or 1 billions of floating point operations per second) was installed in October. Since then, our staff have been working hard in setting up the system and software, and putting it into service. While we are still working on installing some software packages and tools, we are delighted to inform our users that this high performance computer system is now ready for initial service. As the IBM 9076 SP1 system is over hundred times faster than our VAX 6420 system, the new system should definitely be a great boost to the computing power available for supporting our research users who are working on computation-intensive projects. We also expect that the scalable parallel architecture of the new system will stimulate wider interests in parallel computing at the University. The IBM SP1 system is primarily intended for supporting computational-intensive research projects. Interested users can obtain the application forms for using this system from Computer Centre's General Office, Room 223, Run Run Shaw Building.

The IBM 9076 SP1 system has 8 processors inter-connected via a high- performance switch. Each processor has 64MB of memory. An IBM RS/6000 570 system having 12GB of unformatted disk storage acts as the file server for the IBM 9076 SP1 system. The software that have been installed so far include the AIX operating system, LoadLeveler, the Parallel Environment software, Fortran and C compilers, the Visualisation Tool for parallel program development and SPSS. The IMSL Libraries will also be available quite soon.

The IBM 9076 SP1 system has been assigned the node name "hkusp1" with which the system can be accessed from any PCs or workstations on the Campus Network. To facilitate project development requiring powerful front-end workstation and graphics display (e.g. Visualisation), an IBM RS/6000 360 workstation and four IBM M20 workstations have been set up in Room RR-108 in Computer Centre .

To help our users to familiarise and get a quick start with the IBM 9076 SP1 system, we are launching a series of training courses, which cover the topics of AIX operating system, use of workstation, parallel application development tools and loadleveler. For the course of parallel application development, emphasis will be placed on parallel program development using Fortran.

Please refer to the Training News for detailed information.

Campus Wide Information Service for Student PC-Laboratories

In the May/June issue of Computer News, we announced the launch of the Campus Wide Information Service ( CWIS ) which was only available initially to University staff members. However, we have also stated that we would work to extend the service to the student population. Therefore, we are now happy to make a come-back this time and say : CWIS reaches the student PC-laboratories too !

The CWIS is conceived as a platform for distributing information electronically to all users who have access to the Campus Network. From the user's point of view, it appears as another item on the HKUMENU of the file-server which the user is working on. Selection of the CWIS menu entry will on HKUMENU establish a session to the CWIS server where the information resides. No password is required for connection to the CWIS server. Successful connection to the server will bring further menu- pages for accessing the information bases which are supplied and maintained by various information providers.

Information is mainly grouped according to the providers on the menu. For example:

  Computer Centre Office of Student Affairs
  Lecture/Seminar Announcements 
Each of these has its own submenu. To start with, Computer Centre provides 3 items::

 
  - Computer News
  - Terminal Room Opening Hours 
  - Computer Centre Library Catalogue 
Under the 'Office of Student Affairs' sub-menu, there is :

  - Activity of the week ( from DATE/MONTH to DATE/MONTH ) 
The 'Lecture/Seminar Announcements' menu contains scanned circular on announcements of lectures/seminars which are received by Computer Centre and may be of interestS to the student population at large.

We have to point out that the PC-laboratory version of CWIS contains information somewhat different from the version now installed on the departmental PC-servers. However, the commonly interested types of information ( e.g. Lecture/Seminar Announcements ) are available on both servers of PC-laboratories and departments.

The CWIS is able to support both text-based and image-based information ( e.g. 'Lecture/Seminar Announcements' mentioned above ). But regardless of the types of information you might be interested in, reading/viewing the information is easy, as the operation normally involves only a few keystrokes. Help information is provided either as a separate menu-item or incorporated in the browsing-software itself. If you are a new user of the CWIS, you are advised to spend a few minutes in reading the help information and to familiarise with the basic keystrokes, as this may facilitate greatly your navigation in the CWIS information base.

As the success of the CWIS hinges on the amount of information available, student societies, departments and offices, which wish to have an efficient way to disseminate student-oriented information, are encouraged to take advantage of the service by joining CWIS as information providers. Interested parties can contact the undersigned for the details, and user feedback would be much appreciated and deemed important to the refinement of the service.

New Arrangement and Facility Upgrade of Dial-up Service

Computer Centre is providing dial-up access to the central computer systems (including HKUCC, HKUXA, HKUXB, HKUSUB, and HKUVM1) through three separate modem pools of the phone numbers: 8592595, 8597997 and 8597992. The first number is for 24-hour service lines whereas the latter two are only for the "night-service". The 8597992 modem pool has been operating at 14.4 Kbps since July this year while the other two modem pools are only supported by 2400 bps modems.

The "night-service" modems are only operated during the time period of 6:00 p.m. - 8:00 a.m. next day on weekdays (they are also available for service during weekends and holidays). At present, the 2400 bps modem pools are connected to the Dataswitch (D.S.) and the 14.4 Kbps pool is connected to the "HKUDIAL30" service. Both the D.S. and HKUDIAL30 services allow users to choose connection to a required central computer. The main difference between the two is that the latter service has a connection time limit of 30 minutes.

The HKUDIAL30 service has been introduced for a few months and is aimed at providing a better and fair chance for users to gain access to the heavily demanded, but limited dial-up facilities. The 30-minute-limit scheme has proved to be a success and will also be applied to the modem pool 8597997 with effect from January 3, 1994. In fact, the two "night- service" modem pools are being merged into one. Starting from 1994, all dial-up modems, including those 24-hour lines, in Computer Centre will be operating at line speeds of up to 14.4 Kbps (please see below). We expect that the new arrangement and facility upgrade will further improve the service availability and satisfaction of our users.

The new dial-up facilities available starting from January 3, 1994 will be:

Modem/Terminal settings supported:

Data link :  V.32bis (14.4 Kbps)   Error correction : V.42   
             V.32    (9600 bps)    Data compression:  V.42bis 
             V.22bis (2400 bps)    Parity:            None   
             V.22    (1200 bps)    Data Length:       8-bit 
                                   Flow control:      XON/XOFF 
 Operation Mode: 
        
  Modem Pool       Operation Time/Connection    Max.  Terminal Speed 

  8592595          24-hour       /Dataswitch    9600 baud
  8597992/8597997  night-service /HKUDIAL30    19200 baud 
For dial-up access to D.S., the user will be prompted to specify his required system immediately after a modem session is established. For the HKUDIAL30 service, the user has to press the "ENTER" key a few times so as to get the system prompt "Username:" when a modem session is established. After that, entering "HKUDIAL30" will give him a menu for selecting his required system.

Computer Centre is providing a tailored MS-Kermit software for dial- up access to Centre's computer system. An updated MS-Kermit Installation diskette is now available from Centre's General Office, Room RR-223 at nominal cost. Users can also borrow from the office the MS-Kermit Installation Package and make their own copies.

University Libraries CDROM Databases Accessible over the Campus Network

Since early this year, Computer Centre and the University Libraries have been working jointly and actively in setting up the Libraries' CDROM network servers which have been providing service within the libraries for a few months. After a few compatibility problems between the CDROM servers and the standard network-PC and LAN file-server configurations have been resolved, we are pleased to announce that access to the CDROM databases of the Libraries can be available to Pcs of departments through the Campus Network.

For users who have been using network-Pcs and Novell Netware file-servers which are set up by Computer Centre , they can find the new menu entry "HKU Libraries Information Service" on the HKUMENU. When a user selects this menu entry for the first time, the configuration and system files (CONFIG.SYS, NET.BAT, NETWORK.BAT and AUTOEXEC.BAT) of his PC will be modified and rebooting of the system will occur. Further selection of the menu entry will then enable the user's PC be linked to the Libraries information server, and the user will then find a menu of facilities, including CDROM databases, which are provided by the Libraries.

If a user has modified the above mentioned configuration and system files of his PC, he might not be able to gain access to the Libraries CDROM databases by the described procedure. Under such circumstances, please contact the undersigned for help.

For reasonable performance of CDROM database access, it is recommended that a PC with the minimum configuration of a 386 CPU, 2MB RAM, 20MB free hard-disk space, DOS 5.0, and a VGA monitor should be used.

The CDROM database facility is not yet available to those departments which are connected to 3+Open and LAN-Manager servers. In the mean time, Computer Centre is in the process of migrating users of these servers to Novell Netware servers so that all departments on the Campus Network can enjoy the useful service.

Colour Scanner - a New Facility in the Special Facility Room

A HP ScanJet IIc colour scanner has recently been set up and attached to the "Multimedia PC station" in Centre's Special Facility Room (RR-107). The specifications of the scanner and the associated software are summarised as follows:

Scanner type              Flatbed
Maximum document          size 216 x 356 mm (8.5 x 14 inches
Optical resolution        400 dpi
Selectable resolution     12 to 1600 dpi
Scaling                   3 to 200% in 1% increments @400dpi
Scanning speed            20 seconds @400dpi;    
                          15 seconds @300dpi;

                          8-bit (256 grayscale levels);  
                          24-bit (256 levels per colour) 
Image processing Options  Dithering, thresholding, colour correction, 
                          gamma adjustment, mirroring, data inversion, 
                          filtering 
Image Type

The HP ScanJet Iic scanner supports three image types, namely Drawing, Halftone and Photo. The choice of a particular image type in the scanning operation should depend on the characteristics of the pictorial documents being processed so that optimal scanning performance and image quality could be produced. Some suggestions are given below:

The Drawing image type should be used for pictures of solid objects with distinct colours, e.g. cartoon, company logo and other line art. The Halftone image type should be used to simulate shades of gray or colour of the scanned images by varying the density of the dots printed or displayed on a monitor. This image type is generally used for images which has to be printed by the common desktop printers such as laser printers or inkjet printers.

The Photo image type supports more precise grayscale or colour quality for the scanned images than the halftone image type. There are two "photo grayscale" image types - with grayscales of 16 and 256, and two "photo colour" image types - with 256 and Million colours levels.

Image Enhancement Function

The HP ScanJet Iic scanner is provided with the DeskScan II software for processing and enhancement of scanned images. The image enhancement functions of the software are highlighted below:

Automatic Exposure

This is a useful function which initiates the scanning software to make an optimal exposure adjustment for a selected area of a scanned image. This function can simply be invoked by first selecting the area of the scanned image that you want to save, and then clicking the "Automatic Exposure" button for exposure adjustment processing.

Highlight and Shadow

The Highlight and Shadow is a function which can be used to adjust the white and black regions of an image separately and is useful for both colour as well as black and white images. This function is available under the Tools menu and if selected, users can identify the whitest point (the highlight) and the blackest point (the shadow) in the scanned image and then adjust the colours or grays between these two points. More information on using this tool is available from the Quick Help menu.

Emphasis

The Emphasis function can be used to adjust the middle tones of an image separately from the highlight and shadow. This function is available under the Tools menu and if selected, an emphasis curve with 3 control points will be displayed on the screen. The middle tones of an image can be adjusted by moving one or all of the three control points along the emphasis curve. The lowest point controls the darker middle tones, and the highest point controls the lighter middle tones in the image. Moving the control points up lightens the middle tones, while moving the control points down darkens the middle tones. The Emphasis tool must be kept open so that the image emphasis function can be effected. Closing the tool will restore the default emphasis curve. More information on using this tool is available from the Quick Help menu.

Colour Adjustment:

The Color Adjustment function can be used to change the overall cast of a colour image. This function works best with colour halftones or colour photos. Colour Adjustment is available under the Tools menu and if selected, a hexagon and a scroll bar will be displayed on the screen. The user can change the colour hues by clicking any area on the hexagon or to change the colour saturation by clicking the scroll bar. Like the Emphasis tool, the Adjustment tool must be kept open so that its function can be effected. Closing the tool will restore the default colour. More information on using this tool is also available from the Quick Help menu.

IMSL Version 2.0 Available

The IMSL Libraries consist of a large number of very useful FORTRAN subroutines for mathematical and statistical problems. The latest version of the Libraries, i.e. IMSL V2.0, include two products, namely IMSL MATH/LIBRARY Version 2.0 and IMSL STAT/LIBRARY Version 2.0.

These two program libraries are now installed on the VAX/6420 (HKUCC) system in the form of a combined program library: IMSLIB. The IMSL MATH/LIBRARY Version 1.0 will still be kept on HKUCC at its original location until further notice. Users should refer to the IMSL LIBRARY Version 2.0 and Version 1.0 libraries by the equivalent logical names of "IMSLIB" and "IMSL" respectively. However, we would suggest our users who are using the IMSL LIBRARY Version 1.0 to try the new IMSL/LIBRARY by relinking their programs with the object library IMSLIB.

The IMSL Libraries products are designed to be used separately or in combination. Previous versions of the IMSL Libraries, i.e. IMSL V1.0, include the SFUN/LIBRARY product in addition to the MATH/LIBRARY and STAT/LIBRARY products. In version 2.0, programs of the SFUN/LIBRARY product have been integrated into the MATH/LIBRARY product as the IMSL MATH/LIBRARY Special Functions. On the other hand, the IMSL MATH/LIBRARY and MATH/LIBRARY Special Functions continue to be documented separately.

The following reference materials of the new IMSL Libraries can be borrowed from Centre's General Office, Room 223, Run Run Shaw Building:

 User's Manual MATH/LIBRARY                      MS 07077

"At Ease" for Macintosh in Room RR-104

For effective operation, the Macintosh computers which have recently been set up in Room RR-104 are equipped with hard-disks. Since the facilities were put into service in October, we have encountered frequent system failures due to corruption or deletion of files by users. While many of such incidents might be accidental in nature, it had caused considerable inconvenience to users of the facilities and imposed extra burden on our staff in maintaining the systems.

To improve such annoying situation, the hard-disks of the Macintosh systems in Room RR-104 are now protected by the "At Ease" software. Users of the facilities can no longer save their files on the hard-disks of the Macintosh systems and are reminded that they have to save their files on floppy diskettes.

With the "At Ease" software, we have also created a user-friendly interface, which organises the available software programs in the form of large and easy-to-read buttons, to facilitate users to choose the available software programs conveniently.

Macintosh System of Special Facilities Upgraded

The Mac IIcx system in our Special Facility Room RR-108 has been replaced by a faster and more powerful Mac Centris. Unlike the previous Mac Iicx which was provided as a standalone facility, the Mac Centris is connected to the same Ethernet network of the Mac LC IIIs in the Mac Laboratories in Room RR-104. With the network connection, printing from the Mac in the Special Facility Room can now be sent either to the network laser printer in Room RR-103 or to its local laser printer, i.e. the laser printer connected directly to the Mac Centris. If you require to make use of the local laser printer, the existing scheme of paying HK$10 per 2-hour session should be followed. Otherwise, sessions for using the Mac Centris is free and printing produced on the network printer should be collected at the laser counter located near the entrance of Room RR-104 by presenting a laser-printing coupon for cancellation of the equivalent printing units. Laser-printing coupon with 50 printing units can be purchased from our General Office in Room RR-223 at $20 ($16 if a used coupon is returned).

In addition to the Mac Centris system mentioned above, other Special Facilities in Computer Centre include:

Staff and postgraduate students can register to use the Special Facilities. Use of Special Facilities by undergraduate students for project can be arranged. In general, the Special Facilities are available free of charge except in the cases where local laser printing is required. To recover part of the laser-printing costs, sessions requiring the use of laser printers are charged at HK$10 per 2-hour session. Advance booking for sessions of the Special Facilities can be made at the General Office of Computer Centre in Room RR-223 or by telephone 8592491.

Staff-Priority Macintosh in Room RR104

In view of the difficulty encountered by our staff users in competing with the large population of student users in getting access to the Macintosh facilities in Computer Centre , an additional Mac Iicx which is designated as a staff-priority workstation is now installed in Room RR-104 along side with the other 14 Mac LC IIIs. Sessions of this Mac Iicx can only be reserved by staff members of the University. When no staff is using the system, students are free to use it. However, they should give way to staff users when they are so demanded.

The staff priority Mac IIcx system, which bears a "Staff-Priority System" label, is located under the projection screen in Room RR-104. Like other Mac LC IIIs in the room, the Mac IIcx is connected to the campus Ethernet network and shares the same software and laser printing facilities.
