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

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
  • Model based on Infiniscale_III
  • 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.
  • Card Model : Mellanox Technologies MT27500 Family [ConnectX-3] ( ConnectX-3 ).
  • 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] )
  • IP over IB addressing : grisou-[50-51]-ib0.nancy.grid5000.fr ( 172.16.72.[50-51] )

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.
