An environment for performance experiment on multiprocessors

This paper describes an interactive tool for collecting and visualizing performance statistics for programs running on an Alliant FX/8 multiprocessor. The performance “workbench” presented is based on the gprof tool, supplied as a standard component with many Unix systems. The user-friendly environment presented does most of the bookkeeping necessary to compile, execute, and analyze application programs automatically. The environment also supports a graphical interface to review experimental data. The work reported here is a part of the ongoing work on the development of the Faust programming environment at the Center for Supercomputing Research and Development at the University of Illinois at Urbana-Champaign.
