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.


Report Suspicious Malicious Software AT ONCE to Help Stop the Spread

Malicious software (including computer viruses and ransomware), like a chameleon, is good at disguise.  Hidden behind a harmless looking email or webpage, it will attack your PC or mobile device once you fall prey to it.  Unfortunately, users sometimes hesitate to seek help when they suspect their PCs to be compromised.  And while they consider what to do next, their PCs may already infect others, or open up a “backdoor” for hackers to target other computers on the network.  The result can be disastrous.  Hence, if you suspect your PC to be hacked or infected, please report the incident AT ONCE to the IT Service Desk at 3442 8340, via email to, or through message to Microsoft Teamsor to (with full email header).   You can help yourself, keep the University safe, and possibly even allow us to catch a hacker in the act.

Please refer to ”Safe IT at CityU” on best practice for staying on-line.


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.
