Status of OS upgrade for HKUSP2 supercomputer

Introduction

In the last issue of the Computer News #69, we informed our users that 4 of the 32 processor nodes of HKUSP2 have been upgraded from AIX 3.2.5 to AIX 4.2 in early September, 1997. In the past month, our user have been testing their application programs in the new OS environment. They are very satisfied with the results and some of them are now using the new nodes to run their production jobs.

As we are going to complete the process of upgrading all nodes of the HKUSP2 to AIX 4.2 before the end of 1997, users of the HKUSP2 are urged to test and convert their applications to the AIX4.2 environment as soon as possible.  Our staff will try our best to help our users convert their applications smoothly.
