[phenixbb] PHENIX parallel computing?

A parallel version of PHENIX was discussed before. I know that parallelization of refinement is difficult, and probably not worth the effort when there is still a lot of function/methods work. However, running parallel independent tasks could pay off without a lot of work. For example, optimization of WXU and WXC can spawn multiple tasks with different test weights. Annealing tasks could also run multiple jobs, and pick the best result, or even merge results based on real-space fit analysis. Joe Krahn
