I am passing an mpi communicator from python to C. I chose to use boost's mpi communicator as mpi4py does not seem to have good C support. Check it out:
try: from boost.mpi import world
except ImportError: from mpi import world
err = run_with_mpi(infile, world, stdout, stderr, exc)
On systems where boost.mpi is installed, this raises no errors. However, boost.mpi cannot be installed on mac. I installed boost's mpi.so module using homebrew's boost155 formula then added the .so file to pythonpath.
Generally, what does Fatal Python error: PyThreadState_Get: no current thread
mean? What clues does this message give to developers like myself?
Full error message:
