[OMPI users] Using hostfile with default hostfile
Hello, my Cluster has a configured default hostfile. When i use another hostfile for one job i get: cluster-admin@Head:~/Cluster/hello$ mpirun --hostfile ../Cluster.hosts ./hello -- There are no allocated resources for the application ./hello that match the requested mapping: ../Cluster.hosts Verify that you have mapped the allocated resources properly using the --host or --hostfile specification. ... Any ideas for it? Regards, Stefan Kuhne signature.asc Description: OpenPGP digital signature

[OMPI users] default hostfile (Ubuntu-9.10)
Hello, I manage a little HPC-Cluster. It seams like the default-hostfile is located in /etc/openmpi. But when i write my hosts in it, it isn't used by mpirun. How can i use an default hostfile? Regards, Stefan Kuhne signature.asc Description: OpenPGP digital signature
