Hi Freddie,
I have a similar problem.
I installed Anaconda distribution, therefore I am not sure about the
compiler but mpi4py seems to work only with Intel MPI. At first it was
installing using MS MPI with wrong directories, then I corrected them with
correct MS MPI. But the result of famous mpiexec -4 hello.py was always 0.
Then I tried with Intel MPI and it worked. I validated this behaviour with
VS Intel Fortran and the result was the same. When I run mpiexec --version
command I get Intel.
Please find attached the log files produced when I ran the Couette example.
Also could you tell me if Cblas directory is accepted or not, please? I do
not know the execution order, so I cannot say if it is accepted or not.
Thank you,
I wish you a nice day,
Cheers,
Emre
