Using MPI-2 (Gropp et al.) says MPI_SIZEOF() only supports numeric
intrinsic data types. So, I patched OpenMPI 1.4.2 to remove the
declarations of the undefined Logical and Character specific
procedures in ompi/mpi/f90/scripts/mpi-f90-interfaces.h.sh:
output_197 MPI_Sizeof ${rank} CH "c
OpenMPI 1.4.x and 1.5x fail to link a program that calls Subroutine
MPI_SIZEOF using the PGI 10.3 compilers:
$ cat junk.f90
Use MPI
Implicit None
Integer var, size, err
Call MPI_SIZEOF( var, size, err )
Write (*,*) 'Size of Integer var is ', size, ' bytes.'
I managed to compile OpenMPI 1.5rc5 on Linux x86_64 using the PGI 10.3
compilers. All validation tests passed. I have attached the
procedure I followed and the patches I applied to 1.5rc5. I did not
spend the time to find out how to fix configure to include -pthread in
the LIBS Makefile

The fix I posted in http://www.open-mpi.org/community/lists/devel/2010/08/8311.php
for the Redefinition of symbol assert causes a link failure of
opal_wrapper. This is because there are assert() calls in opal/mca/
memory/ptmalloc2/arena.c, which is included in opal/mca/memory/
ptmalloc2/mall

I have access to PGI compilers 10.{3,4,5,8} on an Opteron/InifiniBand

The PGI compiler unnecessarily complains (issues a warning) when 0

Both PGI C and C++ have issues with the inline assembly in OpenMPI.

We still have one known possible regression:

But we posted rc5 anyway (there's a bunch of stuff that has been pending for a
while that is now in). Please test!
