Here you will find documentation on the systems, hardware and software, tools and applications hosted on the CHPC super computers.
New petaFLOP System!
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.
Important documents for all users of the CHPC:
- CHPC Accounts Policy Document Now updated to version 2.5.
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/.

Priority projects:
The CHPC is mandated to support high priority and time-critical projects for weather and pandemic forecasting which need to be prioritised for usage of CHPC resources from time to time. In order to achieve timeous results for national decision-making, the termination of some running jobs may be required without prior warning when cluster usage is high.
