Charm++ parallel programming system

[Eric Bohm <ebohm AT illinois.edu>]

Yes it can.  If you modify the first line of the netconfig file to 
disable the transceiver:

USE_TRANSCEIVER 0

Then it will expect you to load the communication from trace files.

Also, in case there was some confusion in the matter, the IB simulation 
stands for Input Buffered (as opposed to Output Buffered) not as an 
abbreviation for infiniband.
