Phasing out of General-purpose UNIX on Solaris

The General-purpose UNIX on Solaris (also known as moscow20.sys0.cityu.edu.hk) 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. 

Should you require any assistance, please contact the CSC Service Desk csc.servicedesk@cityu.edu.hk.

 

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 csc.servicedesk@cityu.edu.hk 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.

 

Best Practices to Lower Your Personal IT Security Risks

Use of computer hardware and software carries inherent risks related to data privacy and security, data theft, and malicious changes to hardware or software.   To minimize personal risks, users are reminded to update their computer operating systems and applications, as well as mobile apps, to the latest compatible version so as to minimize vulnerabilities and achieve the highest level of protection.

You are advised to:

  • Update your software, web browsers and operating systems to the latest available compatible version;
  • Remove software that you no longer use in your computing devices;
  • Apply security patches to your software once they become available;
  • Avoid clicking on pop-ups, unknown emails, and dubious links;
  • Use strong passwords;
  • Enable firewall protection and install anti-virus software at work and at home;
  • Connect to trusted networks and secure Wi-Fi only;
  • Protect your data and backup your files;
  • Keep abreast of new IT developments by seeking education and training, and
  • Encrypt sensitive data when placing it on removable storage (e.g. USB sticks).

If you are conducting online meetings, you are also reminded to:

  • Password protect the meetings, and provide meeting passwords only to authorized users;
  • Require participants to login;
  • Reject anonymous users or require them to first stand-by in a “waiting room”;
  • Manage access to shared meeting content;
  • Chat mindfully and never share sensitive information in meetings until you are certain who is in attendance;
  • Avoid sharing files or clicking links in chat rooms;
  • Disable unnecessary features;
  • Lock your meeting (as host), if feasible, once all attendees have joined.

If you require any advice or assistance in updating your system, please contact the CSC Service Desk at 3442 8340 or email at csc.servicedesk@cityu.edu.hk.
