Description

Contents view

The platform brings together 6660 cores, 42 GPUs and 49.6 TB of memory. Computing power is rated at around 1 PFlops. It is notably made up of 78 fine nodes, 16 thick nodes, 10 bi-gpus nodes, 3 quad-gpus nodes and 1 octo-gpus node and hybrid nodes equipped in particular with FPGA cards. A visualization node is also available with OpenOnDemand.
The cluster is running through partitions which sometimes have limitations.
