Dear Ross,
As you suggested I issued >which mpirun command. It showed
/usr/bin/mpirun.
bash-2.05b$ which mpirun
/usr/bin/mpirun
And I am not getting any errors while testing the pararllel. I don't know
how to set the environment pvariable for DO_PARALLEL. Details on this is as
follows,
bash-2.05b$ DO_PARALLEL=mpirun -np 4
bash: -np: command not found
What should I do to overcome this problem? Many thanks for your reply.
