Subject: AMBER: amber/pmemd with mpiexec

hi guys,

is anyone using amber with mpich, PBS queuing system and mpiexec?

it seems for me that mpiexec is adding one parameter to the end of
command line and sander/pmemd thinks that this parameter (-execer_id)
belongs to its own parameters and immediately exits with error (unknown

is there any way how to avoid this / force sander/pmemd to ignore
unknown flags on command line?

is it possible that this is just misconfiguration on my side? (i can see
these problems on sander7 with mpich 1.2.5 and mpiexec 0.74 and on pmemd
3.1 with mpich and mpiexec 0.75). shmem versions work fine.
there is also no problem when mpirun is used.

i'd like to use mpiexec mainly because it allows for more transparent
handling of jobs in the pbs queuing system...
