Besides replacing the
`
srun
`
command you need to be aware that
**
MUST always allocates an extra
process
**
, i.e. if you issue a
`mustrun -np 4 ./a.out`
then MUST will start 5 processes instead.
This is usually not critical, however in batch jobs
**
make sure to allocate an extra CPU for this
task
**
.
Finally, MUST assumes that your application may crash at any time. To still gather correctness
results under this assumption is extremely expensive in terms of performance overheads. Thus, if
your application does not crash, you should add
an "
--must:nocrash
"
to the mustrun command to make
your application does not crash, you should add
`
--must:nocrash
`
to the
`
mustrun
`
command to make
MUST aware of this knowledge. Overhead is drastically reduced with this switch.
