Charm++ parallel programming system

[Isaac Dooley <idooley AT gmail.com>]

In AMPI, each MPI rank can be migrated either by a instrumentation
based load balancer, or explicitly by the programmer by calling
MPI_Migrateto(int newpe).

"Chunk" and "Virtual Processor" are synonymous. Virtualization refers
to having many virtual processors that can be migrated among the
available processors.
