======Lengau Cluster======

The main system at the CHPC for high performance computing is a cluster supercomputer called **//Lengau//** ---  cheetah in //seTswana//. This peta-scale system consists of Dell servers, powered by Intel processors, using FDR InfiniBand by Mellanox and is managed by the Bright Cluster Manager. 

The cluster comprises four main parts:

  * 1368 compute nodes
  * 5 large memory nodes
  * 9 GPU nodes
  * 4 PB storage of the Lustre parallel file system

all connected by

  * 56 Gbps FDR Inifniband network interconnect
