I have been using openMPI for my application with intel visual

works fine iwth fortran code compiled in 32bit and run it with openMPI

though I could compile the code successfully with intel fortran 64 bit
and also pointing the openMPI to the corresponding 64 bit files, the
exe would not start and threw the error:
*the application was unable to start correctly (0x00007b)*

This is because the msvcr100d.dll file (this is required by openMPI
even when I run in 32bit mode) is a 32 bit dll file and it probably
requires 64 bit equivalent. I could not find any 64 bit equivalent for
this dll.
My question is why is openMPI looking for this dll file (even in case
of 32bit compilation). Can i do away with this dependency or is there
any way I can run it in 64 bit?
64-bit Windows of course includes full 32-bit support, so you might
still run your 32-bit MPI application.
You would need a full 64-bit build of the MPI libraries for
compatibility with your 64-bit application. I haven't seen any
indication that anyone is supporting openmpi for ifort Windows 64-bit.
The closest openmpi thing seems to be the cygwin (gcc/gfortran) build.
Windows seems to be too crowded for so many MPI versions to succeed.
