Intel compilers support GOMP runtime interoperability, although I don't
believe it is the default. You can use the Intel/LLVM OpenMP runtime with
GCC such that all three OpenMP compilers work together.
Fortran is a legit problem, although if somebody builds a standalone
Fortran 2015 implementation
OMP is yet another source of incompatibility between GNU and Intel
environments. So compiling say Fortran OMP code into a library and trying
to link it with Intel Fortran codes just aggravates the problem.

Hello OpenMPI team,
Thank you for the insightful feedback. I am not claiming in any way that it
is a meaningful practice to build the OpenMPI stack with one compiler and
then just try to convince / force it to use another compilation environment
to build MPI applications. There are occasions thoug
Please separate C and C++ here. C has a standard ABI. C++ doesn't.

Even if i do not fully understand the question, keep in mind Open MPI
does not use OpenMP, so from that point of view, Open MPI is
independant of the OpenMP runtime.
Let me emphasize on what Jeff already wrote : use different installs
of Open MPI (and you can use modules or lmod in order to choose
I think Jeff squires summed it up.

Thanks for the note. How about OMP runtimes though?

FWIW, we always encourage you to use the same compiler to build Open MPI and
your application.
Compatibility between gcc and Intel *usually* works for C and C++, but a)
doesn't work for Fortran, and b) there have been bugs in the past where C/C++
compatibility broke in corner cases. My $0.02:
On Linux and Mac, Intel c and c++ are sufficiently compatible with gcc and g++
that this should be possible. This is not so for Fortran libraries or Windows.

Dear OpenMPI list,
As far as I know, when we build OpenMPI itself with GNU or Intel compilers
we expect that the subsequent MPI application binary will use the same
compiler set and run-times.
Would it be possible to build OpenMPI with the GNU tool chain but then
subsequently instruct the OpenMPI
