I hadn't even thought about this. From the mpiexec (mpich2 and mpich3) man
page:
ENVIRONMENT VARIABLES FOR MPIEXEC
The following environment variables are understood by some
versions of mpiexec . The command line arguments have priority over
these; that is, if both the environment variable and command line
argument are used, the value specified by the command line argu-
ment is used.
MPIEXEC_TIMEOUT
- Maximum running time in seconds. mpiexec will
terminate MPI programs that take longer than the value specified by
MPIEXEC_TIMEOUT .
...etc.
If you use mpich2, you can just set this environment variable when you run
the tests. From what I can see, no such analog for OpenMPI (too bad).
All the best,
Jason
