MeSU supercomputer offers three types of resources :

  • alpha : a very large shared-memory computer with 16 TB memory,
  • beta : a distributed-memory computer with 144 nodes,
  • gamma : a group of computers equipped with GPUs.


MeSU-alpha is a SGI UV2000 system, it is a very large SMP machine which offers a total of 16TB of RAM memory associated with 1024 cores.
It is made of 64 computes blades, each of which made of 2 motherboards (or nodes), equipped with one Intel Xeon (Sandy Bridge) of 8 cores and with a local memory of 128Gb. The nodes are connected by a Numalink system (version 6) developed by SGI, which allows for the large shared memory.

  • Architecture : Intel Sandy Bridge
  • Processors : 128x Intel Xeon E5-4650L (2.6 GHz, 8 cores)
  • Memory : 16TB DDR3 1600Mhz
  • Interconnect : SGI Numalink 6 12.5 Gb/s
  • Dedicated storage : 90 TB


MeSU-beta is a SGI ICE-XA system, it is a distributed cluster which offers 3456 high performance computing cores, distributed in 144 nodes of 24 cores. It is associated with a fast storage system based on a Lustre filesystem. MeSU-beta is a extremely energy efficient server, and is equipped with a water cooling distribution unit (CDU).

MeSU-beta is equipped with 144 computes blades, each of which made of one motherboard (or node), equipped with two Intel Xeon Haswell of 12 cores each, and with a local memory of 128GB. The nodes are connected by an Infiniband network, which allows for fast communication between them.

  • Architecture : Intel Haswell
  • Processors : 144x 2 Intel Xeon E5-2670v3 (2.7 GHz, 12 cores)
  • Memory : 144x 128GB DDR4 2133Mhz
  • Interconnect : Mellanox Infiniband FDR 56 Gb/s
  • Lustre Storage : 170 TB


MeSU-gamma is made of two SGI servers which offer Nvidia GPUs.
These nodes can be used for GPU-accelerated tasks (with CUDA for example) or for remote 3D visualization.
It is associated to the same fast storage system as MeSU-beta.

  • Architecture : Intel Haswell
  • Processors : 2x 2 Intel Xeon E5-2620v3 (2.4 GHz, 6 cores)
  • GPUs : 2x Nvidia Quadro K5200 8GB
  • Memory : 2x 256GB DDR4 2133Mhz
  • Interconnect : Mellanox Infiniband FDR 56 Gb/s
  • Lustre Storage : 170 TB
