Hi,
Is it possible to run task on compute nodes having InfiniBand HCA from a master node that lacks IB HCA using Torque/Grid Engine?
Please guide if it is possible.
Intel MPI 4.1.1.036 is installed on all cluster machines.
The network configuration is as follows:
Master Node: (2xXeon E5-2450/96GB/CentOS 6.2/NFS Services over Ethernet) - 1 No.
Compute Nodes: (2xXeon E5-2450/96GB/TrueScale QDR Dual-port QLE7342/CentOS 6.2/NFS Client over GbE) - 4 Nos.
IP Addresses (GbE) : Master Node: 10.0.0.221 - Hostname: mnode; Compute Nodes: 10.0.0.222 .. 225 - Hostnames: c00 .. c03
IP Address (ib0): Master Node: N/A; Compute Nodes: 192.168.10.222 .. 225 - /etc/hosts -> c00-ib; c01-ib; c02-ib; c03-ib
Additionally, if mpiexec.hydra can be used, then what is the command-line from master node to directly run without Torque or Grid Engine.
