abstract

ParaGraph is a graphical display system for visualizing the
behavior and performance of parallel programs on message-passing
parallel computers. It takes as input execution trace data provided
by PICL (Portable Instrumented Communication Library),
developed at Oak Ridge National Laboratory and available from
netlib. PICL optionally produces an execution trace during an
actual run of a parallel program on a message-passing machine, and
the resulting trace data can then be replayed pictorially with
ParaGraph to display a dynamic, graphical depiction of the
behavior of the parallel program. ParaGraph provides several
distinct visual perspectives from which to view processor
utilization, communication traffic, and other performance data in
an attempt to gain insights that might be missed by any single view.
