[mvapich-discuss] Error running test program after MVAPICH2-1.4.1 installation

[Jonathan Perkins]

It looks like we're having problems with executing the command due to
the extra options that need to be passed.  The error message indicates
that it is trying to execute `pmemd -O -i min1.in -o min1.out -inf
...', instead of `pmemd'.  The problem seen in your first email seems
to be resolved since `mpispawn' is now found but we'll look into this
2nd issue.  As a work around in the meantime, you should be able to
create a script that simply calls the real binary with the needed
options.

Ex:
#!/bin/sh
# filename: pmemd-wrapper
# permissions: 755
pmemd -O -i min1.in -o min1.out -inf min1info -p C0101sol.prmtop -c
C0101sol.inpcrd -r C0101solmin1.rst -ref C0101sol.inpcrd

mpirun_rsh -np 4 -hostfile hostlist pmemd-wrapper
