Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Evghenii,

At present, there isn't a way to accomplish this separation, beyond
placing the code in the body of larger atomic blocks in sequential
functions defined in a .cpp file. Some higher-level languages that
we're building to simplify Charm++ development may provide this
separation more directly.
