Summary

0013998: FindMPI MPIEXEC_MAX_NUMPROCS is hard coded to 2

Description

In FindMPI, MPIEXEC_MAX_NUMPROCS is hard coded to 2. The seems very confusing given its description:

set(MPIEXEC_MAX_NUMPROCS "2" CACHE STRING "Maximum number of processors available to run MPI applications.")

It seems that it should either try to figure out the number of available cores to state that it is explicitly meant to be overridden.

It isn't mentioned at all in the docs.

Notes
(0032584) Robert Maynard (manager) 2013-03-11 15:48	This was added back in for backwards compatibility it seems on commit 5b3e62c7bc11eab36548. The majority of projects that use this variable do so when launching MPI tests. The documentation should at minimum state that the variable is actually set to the minimum number of processors to be considered a parallel job, which is 2.
