[SCore-users-jp] [SCore-users] Resource problem

[Nick Birkett]

Hi - I am getting a funny resource problem on a machine that has been running 
Score 5.0.1 for 200 days. 

I can run rpmtest, scstest between 2 nodes.
I can run a parallel job on each node separately,
but when I try to run both hosts together I get a  Resource unavailable
error.

A Myrnet line card was replaced on Friday. Could it be a cable is
in the wrong hole (but surely rpmtest and scstest would not then work )?

I have tried restarting scoreboard and msgbserv and rebooting comp29,30.

Anyone have an idea about this ?

The jacob_mpi application is a standard one that works up to 64 processes.
