A lot of ways to run the same way of calculating pi. Some of them are dumb.

pi_examples's Issues

Add jython version

One of these days...

Add cython version(s) that use cython annotations, decorators, etc

The current cython version (ac92dd5) uses no actual cython specific code - it simply passes pure python code through cython.

This is known to provide minimal (typically up to 10%) speed ups.

Suggest use of e.g. type declarations, if appropriate use of cmath, removal of GIL to add real usefulness of Cython.

Add multi-threaded Python version(s)

Add multi-threaded pthreads C version

`c_hybrid_mpi+openmp_dir` doesn't seem to actually use OpenMP

I haven't dug into the code, but I noticed that running the c_hybrid_mpi+openmp_dir example on a Grace-Grace system it doesn't seem to use multiple threads, setting the environment variable OMP_NUM_THREADS doesn't have any effect.
