Lengau: a fully-fledged petascale system

CHPC’s Lengau Cluster is now a fully-fledged petascale machine with a High Performance Linpack score of 1.029 petaflops per second.

This follows a recent upgrade of the cluster which involved the addition of five new compute racks (each consisting of 72 nodes), effectively resulting in an additional 360 nodes (24 cores/node and 64GB/node) for Lengau.  The total number of nodes on Lengau is now 1368 and it has a total core count 32 832 cores.  The full total of 19 compute racks of Lengau is now available to users.  

With this upgrade Lengau becomes the first petascale compute cluster on the African continent.
