Charm++ parallel programming system

[Eric Mikida <epmikida AT hpccharm.com>]

Some recent issues have cropped up related to array maps in Charm++ that has 
led us to start re-evaluating the current API and usage of array maps. Before 
diving in though, I had a couple of questions for array developers:

1) Do you use any built-in Charm maps other than the default array map?
2) Does your application define it’s own array maps?
  2b) If you define your own maps, do your maps define and use their own 
entry methods?
  2c) Do you use a single map instance to manage multiple chare arrays in a 
non-trivial way?

Right now the plan is to clean up the API and how the maps are instantiated, 
which probably will also involve change maps from group chares to just 
regular C++ objects.

Thanks
