System architecture

MesoBFC cluster is composed of two kind of partitions: CPU and GPU partitions.

CPU partitions

mpi1 = Skylake_AVX512 processors

The first CPU partition mpi1 is composed of 36 nodes (864 cores), based on Intel processors.

  • 854 cores
  • 3456 GB RAM
  • 71.9 Tera FLOP/s
Hardware modelDell C6420
CPU ModelSkylake_AVX512
ProcessorIntel(R) Xeon(R) Gold 6126
Total processor per node2
Total cores per processor12
Total cores per node24
Clock rate2.60 GHz
RAM92 GB
Interconnect

Nodes are interconnected using OMNI-PATH network

mpi2 = Sapphire Rapids processors

The second CPU partition mpi2 is composed of 48 nodes, based on Intel Sapphire Rapids processors.

  • 2304 cores
  • 12288 GB RAM
  • 191.7 Tera FLOP/s
Hardware modelDell C6620
CPU ModelSapphire Rapids
ProcessorIntel(R) Xeon(R) Gold 6442Y
Total processor per node2
Total cores per processor24
Total cores per node48
Clock rate2.60 GHz
RAM252 GB
Interconnect

Nodes are interconnected using Mellanox infiniband network

nompi

The nompi partition is currently made of 2 nodes picked from the mpi2 "Sapphire Rapids" rapid partition.

This partition is dedicated to small jobs that cannot fill an entire node.

In future, this partition may contain heterogeneous nodes (different CPUs, RAM, etc.) that are not interconnected in Infiniband.

transfer

The 'transfer' partition should only be used for offline/batch data copy jobs, not for calculation jobs.

Currently, this partition comprises 4 slots located on the login node.

GPU partition

The 'gpu' partition contains nodes equipped with GPUs.

Currently, the queue is made up of 3 nodes, each equipped with 2 H100 GPUs.
