HPC Networks
Several HPC Networks are available.
Omni-Path 100G on grele and grimani nodes
grele-1togrele-14have one 100GB Omni-Path card.grimani-1togrimani-6have 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-1tographene-144have 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 :

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.
