Dear All,
I need some help in this. I have a OSCAR cluster running with 8 nodes. I was
doing a benchmark with HPL on top. The prolem is that whenever i run the command
$ mpirun -np 8 xhpl
I get the following error. My /etc/hosts enty is saying something else. my
server is oscarserver.cluster and my nodes are of the name oscarndode1.cluster thorugh
oscarnode8.cluster.Interestingly mpich takes some other name ( ?) for the nodes . Any
idea why ?
p0_3308: (60.903600) Procgroup:
p0_3308: (60.903822) entry 0: oscarserver.cluster 0
/home/user/hpl/bin/Linux_PII_CBLAS/xhpl user

Subject: RE: [Oscar-users] how to update the new user in slave nodes?
First, make sure you are root, then if it is not in /usr/sbin/sync_users,
check if the rpm is installed (`rpm -q sync-users-oscar`). If it isn't you
can install it, but that points to other possible problems with your cluster.
