high performance computing cluster - child nodes speed test
Hello,
we have RHEL5 Cluster, 1 head node and 8 diskless child nodes, users noticed that the last node, node8, has a slower computing speed than all the other nodes.
"The cluster is used to compile fortran programs using MPICH2"
All the nodes are the same hardware, identical to each others, I have changed the network cable just in case if it was bad cable but that didn't help.
What tool(s) can we use to proof/test if the speed of any node is really different than other nodes in the cluster?
Thank you in advance
