CHPC petaFLOP System

The CHPC has 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.

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.
