Charm++ parallel programming system

[Ramprasad Venkataraman <ramv AT illinois.edu>]

Laercio,

We also have another standalone barnes-hut benchmark thats written in
charm++. This one has been tested and used recently. You should be
able to find it at:
git://charm.cs.illinois.edu/benchmarks/barnes.

I believe Pritish will be able to explain any differences between the
two programs.

Meanwhile, someone here will try to get your patch committed. Thanks.
Ram
