Analyzing Program Performance

Prism provides support for Trace Normal Form (TNF) performance analysis for Sun MPI message-passing programs. By redirecting the LD_LIBRARY_PATH environment variable, you can use a TNF-instrumented Sun MPI library to generate data on the performance of your Sun MPI routines. Then, you can display and analyze the TNF data in timeline graphs, scatter plots, histograms, and tables.

See Chapter 6, Obtaining MPI Performance Data, for a discussion of MPI performance analysis.
