Simple Coarray Fortran examples for teaching.
Using gfortran 5.1, mpich3, and the OpenCoarrays MPI backend, one compiles and runs these programs as follows:
mpifort diffusion/diffusion-coarray.f90 -fcoarray=lib -o diffusion/diffusion-coarray -L ${PATH_TO_OPENCOARRAY_LIB} -lcaf_mpi
mpirun -np 8 diffusion/diffusion-coarray A Makefile is provided which you can edit to include the relevant paths.
If you don't have gcc 5.1 and opencoarrays installed, you can use the available vagrant VM; documentation for downloading the vagrant VM or building it can be found in the vm directory
