xmpi - 2.2.3b8-14+b2 main

MPI is a standard for writing parallel processing programs using
a well defined Message Passing Interface.
.
XMPI can acquire and display extensive detail on an application's MPI
communication, including the following:
o process synchronization status: running, system or blocked
o message queue contents
o source, destination, root ranks
o MPI function name
o communicator
o data type
o message count
o tag
The above information is acquired from on-demand snapshots of
application status using debugging hooks in the MPI implementation or
from a trace log of communication activity.
