I know on Windows, for Fortran + MPI, we can use Intel OneAPI in which Fortran and MPI are already configured and the performance is good.
But my question is, how about gfortran and MPI on windows?
How to make gfortran with openmpi/mpich work on windows? Can someone show an example?
I have tried cygwin64 and installed gfortran and openmpi there, however the performance seems is much slower than intel OneAPI.
On Ubuntu one can simply type
sudo apt install gfortran mpich
Then everything is fine.
On windows is there a similar way such that gfortran and mpi are easily installed?
Thanks much in advance!
