Here you will find documentation on the systems, hardware and software, tools and applications hosted on the CHPC super computers.

The CHPC has a new DELL cluster since mid-2016, named Lengau (cheetah), that can perform at petaFLOP level and replaces the old Tsessebe cluster.

Along with the new system are new accounts, new policies and new adventures.

• CHPC Accounts Policy Document Now updated to version 2.4.
• Procedure to follow for making use of CHPC resources

To register for the new system you need to apply online.

In order to obtain access to the cluster registration as either a Principal Investigator (PI) or Normal User on the new CHPC User Database is required. It is further required from approved PI's to register a single Research Programme to which registered users can be added as members. Job submissions will draw from cpu hour allocations associated with the respective Research Programmes. Full details of these new procedures and steps to follow to get registered may be found at the following link to the user database: https://users.chpc.ac.za/.
