Charm++ parallel programming system

[Ramprasad Venkataraman <ramv AT illinois.edu>]

Sagar,
If your intention is to use multicasts or reductions on chare
arrays/sections, then our current recommendation is to use the
CkMulticast library that is bundled together with charm.

documentation is in section 3.9.13 (Array Sections) of the charm++ manual:
http://charm.cs.illinois.edu/manuals/html/charm++/3_9.html

working example program is in the following location in the charm source tree:
tests/charm++/delegation/multicast

Let us know if this will satisfy your intended use cases or if you are
looking for something else. Meanwhile, we'll look into the broken
comlib example programs.

Thanks
Ram
