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.

The goals and architecture of the Faust environment are presented. The components of the Faust user-interface library are described. The Faust program abstraction supports three levels of detail: the process graph, the subroutine interconnection graph, and the program source code. Each level is described in detail.>

The subject of integrated programming environments for scientific computing has become very popular over the last few years. Environments such as Rn [CCHK87] are being constructed to help coordinate the disjoint activities of editing, debugging, and performance tuning typically seen in the program development cycle. One key aspect of an integrated development setting is the library of user interface tools which are available to the environment builders. Projects such as Andrew [MSCH86] have begun to construct reusable user interface libraries for client applications. This paper describes the interface tool kit for the Faust project being conducted at the University of Illinois. Faust is targeted at building a coherent development environment for scientific applications through the use of a library of portable user interface utilities.
