Hi,all£¬ recently I've installed OpenMPI on our cluster (4 nodes, each node got one installation), but finally I found it could not work well with the underlying resource management system SLURM. That is,after I typed the following, it seemed mpirun hang there:
[semper@IA64_node2] srun ¨CN 2 ¨CA [semper@IA64_node2] mpirun -np 2 /tmp/cpi I installed OpenMPI and SLURM all under HOME directory of user semper , and each works well separately. I can test with such commands: "srun ¨CN 4 /bin/hostname ¨Cs", there goes correct results( 2 from node2, and 2 from node4). And "mpirun ¨Cnp 4 cpi" works well on the local node.btw ,following is some information. Node User HOME OpenMPI(SLURM) IA64_node0 semper /home/disk0/semper $HOME/openmpi(slurm) IA64_node1 semper /home/disk1/semper $HOME/openmpi(slurm) IA64_node2 semper /home/disk2/semper $HOME/openmpi(slurm) IA64_node3 semper /home/disk3/semper $HOME/openmpi(slurm) PATH=$HOME/openmpi/bin:$HOME/slurm/sbin:$HOME/slurm/bin:$PATH LD_LIBRARY_PATH=$HOME/openmpi/lib:$LD_LIBRARY_PATH Does that different HOME path matter? Can anybody detail me how to configure these two to work together?[ It nearly drives me crazy 8-( ] Thank you.
