This will not work, as the compilers have different views on e.g.
boolean
variables and values, so parameter passing from Your code into
OpenMPI
will be botched up. Currently, You may only use C / Fortran
Compiler from
one vendor.
That's kind of surprising, I don't know why you would want to require
that bool and LOGICAL have the same values. We (and Intel) both do
bool like g++ does, but we each do LOGICAL to match the history of our
Fortran compilers. I never imagined anyone would think these should be
the same.
I believe this is something that is fixed in the upcoming 1.0.2
release. One of those things that slipped through the cracks during
the runup to 1.0, since only a couple of functions in the MPI
interface deal with Fortran LOGICALs directly (other than sending
them around, that is).
