Hi Jerry,
good you could build Toon's code.
Your idea of using the OpenCoarray tests to test caf_shmem made me think about
how to do it the easiest.
I came up with the following:
1. Pull a recent OpenCoarray source tree from Github or use a clean existing
one.
2. Apply attached patch.
3. Create a build directory for OpenCoarrays.
4. Copy or link libcaf_shmem.a from a recent gfortran build to the OpenCoarray
build directory.
5. Do a cmake <OpenCoarraysSrcDir> in the build directory.
6. Now cmake --build . && ctest . should test using caf_shmem.
Notes:
- Some tests have been deactivated, because they use MPI-features, that are not
present in caf_shmem.
- There are still two test failing about some test on cafrun. Those are ok,
because the file has been patched and I can't find where the test is coming
from. Unimportant!
- You need an update patch set for caf_shmem, because the OpenCoarray tests
revealed some/a lot of issues in caf_shmem. I am currently regtesting the
patch and will publish as soon as it regtests cleanly.
Regards,
Andre
