Charm++ parallel programming system

["Celso L. Mendes" <cmendes AT illinois.edu>]

Hi Evghenii,

Yes, all those features (i.e. migration, load balancing, fault tolerance)
are available in AMPI, as it uses the same runtime support from Charm.
The goal of AMPI is exactly to make them available to "legacy" MPI codes,
meaning MPI codes that already exist.

It is very easy to add them to an MPI program *if* the program does
not use global or static variables. If there are any such variables,
they must be treated in some fashion. We have a few available methods
(automated and manual) to handle this, but there isn't a universal
solution that will solve all cases.
