HPC Networks

Several HPC Networks are available.

Omni-Path 100G on grele and grimani nodes

  • grele-1 to grele-14 have one 100GB Omni-Path card.
  • grimani-1 to grimani-6 have one 100GB Omni-Path card.
  • Card Model: Intel Omni-Path Host Fabric adaptateur series 100 1 Port PCIe x8

Omni-Path 100G on grvingt nodes

There's another, separate Omni-Path network connecting the 64 grvingt nodes and some servers.

Topology, generated from opareports -o topology:

More information about using Omni-Path with MPI is available from the Run_MPI_On_Grid'5000 tutorial.

Infiniband 20G on griffon nodes

Infiniband has been removed from these nodes

Infiniband 20G on graphene nodes

  • graphene-1 to graphene-144 have one 20GB Infiniband card.
  • Card Model : Mellanox Technologies MT26418 [ConnectX IB DDR, PCIe 2.0 5GT/s] ( ConnectX ).
  • Driver : mlx4_ib
  • OAR property : ib_rate=20
  • IP over IB addressing : graphene-[1..144]-ib0.nancy.grid5000.fr ( 172.18.64.[1..144] )

Switch

  • Infiniband Switch 4X DDR

  • 1 commutation card Flextronics F-X43M204
  • 12 line cards 4X 12 ports DDR Flextronics F-X43M203

Interconnection

Infiniband network is physically isolated from Ethernet networks. Therefore, Ethernet network emulated over Infiniband is isolated as well. There isn't any interconnexion, neither at the L2 or L3 layers.

Infiniband 56G on graphite/graoully/grimoire/grisou nodes

  • graoully-[1-16] have one 56GB Infiniband card.
  • grimoire-[1-8] have one 56GB Infiniband card.
  • graphite-[1-4] have one 56GB Infiniband card.
  • grisou-[50-51] have one 56GB Infiniband card.

  • Driver : mlx4_core
  • OAR property : ib_rate='56'
  • IP over IB addressing : graoully-[1-16]-ib0.nancy.grid5000.fr ( 172.18.70.[1-16] )
  • IP over IB addressing : grimoire-[1-8]-ib0.nancy.grid5000.fr ( 172.18.71.[1-8] )
  • IP over IB addressing : graphite-[1-4]-ib0.nancy.grid5000.fr ( 172.16.68.[9-12] )

Switch

  • 36-port Mellanox InfiniBand SX6036
  • Documentation
  • 36 FDR (56Gb/s) ports in a 1U switch
  • 4.032Tb/s switching capacity
  • FDR/FDR10 support for Forward Error Correction (FEC)

Interconnection

Infiniband network is physically isolated from Ethernet networks. Therefore, Ethernet network emulated over Infiniband is isolated as well. There isn't any interconnexion, neither at the L2 or L3 layers.
