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

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.
