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
Omni-Path 100G on grvingt nodes
There's another, separate Omni-Path network connecting the 64 grvingt nodes and some servers. The topology is a non blocking fat tree (1:1).
Topology, generated from opareports -o topology:
More information about using Omni-Path with MPI is available from the Run_MPI_On_Grid'5000 tutorial.
NB: OPA (Omni-Path Architecture) is currently not supported on Debian 12 environment.
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
Omnipath 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.
