Notes:
-----
Contains two "extended" examples:
1) scatter-gather, with different parallel backends
2) optimization, with different parallel backends
"scatter-gather" demonstrates scatter-gather from mpi4py,
and requires numpy and mpi4py. "all_scatter_gather*"
demonstrates the pathos versions of scatter-gather,
using a Pool and map. "all_scatter-gather*" will leverage
pyina (if pyina is available).
"optimize" demonstrates using pathos to extend optimization
to leverage parallel computing. "optimize*" requires the
mystic optimization framework. "optimize0" demonstrates
an example optimiztion with mystic, and "optimize" converts
"optimize0" to use a map function. "optimize_powell"
demonstrates the common API for the different parallel
backends in pathos (and pyina). "optimize_XXX_YYY_ZZZ"
shows different specific combinations of objective function
XXX={rosen, cheby}, optimization algorithm YYY={powell, diffev},
and map function ZZZ={map (serial), mpmap (multi-process),
ppmap (parallel python), mpimap (MPI)}. Note that "optimize_powell"
and "optimize_cheby_powell_mpimap" both require pyina to be
installed.
