Annai/PMA Multi-level Hierarchical Parallel Program Performance Engineering

Brian J.N.Wylie&Akiyoshi Endo

TR-96-03,April1996

Abstract.The Annai integrated tool environment is currently being developed to

help exploit the inherent power of distributed-memory parallel computers with

standardized languages and convenient programming support.As they are de-

signed and implemented,prototypes of the compiler,debugger and performance

tools are used and evaluated by a team developing applications and libraries,lead-

ing to further re?nements.Portable application development is supported in High

Performance Fortran and/or with explicit message passing,using MPI as the ma-

chine interface.

Key design aspects of the performance monitor and analyzer(PMA)component

were usability and scalability.Integration within a uni?ed tool environment allows

the user investigating performance to interact with the high-level source code and

distributed arrays during program execution on the same terms as when using

the parallel debugger.Detailed data distribution and other program information

furnished by the parallelization support and compilation systems are also exploited

for additional insight.Scalability has been considered by providing powerful,

directed analysis and interactive graphical summaries within a familiar hierarchical

framework with source reference.And when ultimately required,detailed views

of the time-varying behavior of individual processes and communication events

can also be browsed as desired.

Keywords.parallel program engineering environment,performance analysis/visualization, HPF/MPI
