Detailed Description

Charm Kernel--the groups and chares level of Charm++.

These routines implement a basic remote-method-invocation system consisting of chares and groups.

These routines are implemented in ck.C.

There is no migration. All the bindings are written to the C language, although most clients, including the rest of Charm++, are actually C++.
