Phasing out of General-purpose UNIX on Solaris

The General-purpose UNIX on Solaris (also known as was set up a decade ago to give colleagues access to the UNIX environment.  With general availability of Linux operating systems and the support for installing a Linux distribution under the Windows 10 environment, the service demand has been extremely low.  To better utilize the university resources, the Computing Services Centre (CSC) will retire this service on 31 July 2020.  Users are advised to transfer their old data to their machine before the retirement date.

Centralized High Performance Computing (HPC)

To better utilize university resources, the University management has decided to set up a centralized HPC cluster under CSC’s management.  The centralized HPC is available for all departments, supporting teaching, learning and research needs. 

Along the line of this direction, some HPC facilities previously acquired by departments (with around 1,600 CPU cores, 12 double-precision and 8 single-precision GPU cards) are now managed by the CSC.  On top of this, new HPC facilities will be put in place in July 2020 which will increase the computational power to around 500 teraflops for CPU and 400 teraflops for GPU. 

Interested parties may contact the CSC at to indicate their needs and provide the list of desired applications.  The CSC will help evaluate if the applications can be run on the HPC environment.
