Charm++ parallel programming system

[Jonathan Lifflander <jliffl2 AT illinois.edu>]

Sorry about the belated response.

An SDAG serial block only indicated that the block is C++ code. It has
no relation to threaded entry methods. The point in the manual means
that serial only indicated the block on code will execute without
preemption. Note that an SDAG entry method is different than an
ordinary entry method, so it can be suspended at a "when" while
Charm++ is waiting for incoming data.

If you need more explanation let me know.

Thanks,

Jonathan
