Abstract :
This paper describes an ongoing effort to provide a profiling environment for MPI applications running on the NEC Cenju-3, an MPP research prototype. Highlights of these efforts include automatic management of dynamic trace buffers, efficient post-processing, and user-driven visualization support. Modern virtual memory support found in the Cenju-3 operating system provides automatic management of dynamic trace buffers. Parallelization provides post-processing efficiency. Researchers from an NSF Grand Challenge Application Group are guiding the development of the visualization tool
