IP networks in use

You have to use a public network range to run an experiment between several Grid5000 sites.

Public Networks

  • computing and ib : 172.16.64.0/20
  • virtual : 10.144.0.0/14

For Infinband (ib) see High Performance Networks

Local Networks

  • admin : 172.17.64.0/20

Physical link details

The following diagram show a view of the central router, a hp procurve 5406zl, named sgravillon1.

  • All internal links are 10GB CX4.
  • Renater link is 10GB optical fiber.

High Performance Networks

Infiniband 20G on griffon nodes

Nodes

  • griffon-1 to griffon-92 have one 20GB Infiniband card.
  • Card Model : Mellanox Technologies MT26418 [ConnectX IB DDR, PCIe 2.0 5GT/s] ( ConnectX ).
  • Driver : mlx4_ib
  • OAR property : ib20g=YES ( Monika ).
  • IP over IB addressing : griffon-[1..92]-ib.nancy.grid5000.fr ( 172.16.67.[1..92] )

Switch

  • Infiniband Switch 4X DDR
  • Model based on Infiniscale_III
  • 1 commutation card Flextronics F-X43M204
  • 11 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 data link layer nor at the network layer.

Infiniband 20G on graphene nodes

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 : ib20g=YES ( Monika ).
  • IP over IB addressing : graphene-[1..144]-ib.nancy.grid5000.fr ( 172.16.66.[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 data link layer nor at the network layer.

Myrinet 10G on griffon nodes

Nodes

  • griffon-11 to griffon-14 have one 10GB Myrinet card.
  • Card Model : Myrinet 10G ( [1] ) 10G-PCIE-8B-C NIC
  • Driver : myri10ge
  • OAR property : ib20g=YES ( Monika ).
  • Ethernet. IP addresses : griffon-[11..14]-myri0.nancy.grid5000.fr ( 172.16.67.[93..96] )

Interconnection

The nodes having myrinet configured are connected to the 10G Ethernet interfaces of the switches sgriffon|1-3] as following:

  • griffon-11 to sgriffon1
  • griffon-12 to sgriffon1 (the configuration is not working probably due to the switch configuration)
  • griffon-13 to sgriffon2
  • griffon-14 to sgriffon3
