[mvapich-discuss] default envs for mpiexec

[Christian Guggenberger]

Hi,

I'd like to know if there's an easy way to add default environment
variables to mpiexec. We are experience trouble with SRQ on some
hardware and I would thus disable SRQ globally by default. My current
approach would have been to add

envToSend['MV2_USE_SRQ'] = str(0)

into mpiexec.py, but this would disable the option to explicitely enable
SRQ via 'mpiexec -env MV2_USE_SRQ 1 ...'

Anyone on the list who'd know of a more elegant solution ?

thanks a lot,
 - Christian
