Hello, I followed the instructions on the FAQ page to configure and compile openmpi so that it should work with Torque. ./configure --with-tm=/usr/local --prefix=/usr/local The option --disable-server was used to configure torque on the compute nodes. I got openmpi compiled without any error message on the head and compute nodes.
I can use $ mpirun -np 2 --host node1,node2 a.out to run parallel programs without any problem. However, when I submit the following script with qsub ____________________________________________________________________ #!/bin/sh # PBS -N Test PBS -o /home2/user2/test.sh.o PBS -l nodes=8 mpirun /home2/user2/a.out # a.out simply prints out # of procs and its ID ____________________________________________________________________ I got the following output and error messages. Output: N. of procs = 1, proc ID = 0 Error messages: /var/spool/torque/mom_priv/jobs/198.my_head_node.SC: 3: PBS: not found /var/spool/torque/mom_priv/jobs/198.my_head_node.SC: 4: PBS: not found /var/spool/torque/mom_priv/jobs/198.my_head_node.SC: 5: PBS: not found /var/spool/torque/mom_priv/jobs/198.my_head_node.SC: 6: PBS: not found /var/spool/torque/mom_priv/jobs/198.my_head_node.SC: 7: PBS: not found /var/spool/torque/mom_priv/jobs/198.my_head_node.SC: 8: PBS: not found I'm new to OpenMPI and Torque. I really appreciate it if you can give me some insights. Thanks! Best, Steve
