Can you build OMPI as a 32 bit library and see if that works any better?
So you mean I shall leave the whole OFED stack as 64 bit and build only openmpi as 32 bit?
I believe the OFED user libraries will need to be 32 bit also or the 32 bit MPI libraries will not be able to use them.
How must I configure openmpi that it'll be definitely built as 32bit?
You need to change the CFLAGS, CXXFLAGS, FFLAGS and FCFLAGS in the configure line such that you replace "-m64" with "-m32" or just "-m32" if "-m64" is not there?
