Reproducible Measurements of MPI Performance Characteristicsthe mistakes often made in attempting such measurements and the consequences of such mistakes. We describe ., a suite of performance measurement programs developed at Argonne National Laboratory, that attempts to avoid such mistakes and obtain reproducible measures of MPI performance that can be use

Performance and Predictability of MPI and BSP Programs on the CRAY T3E model prediction. The BSP Without Barriers Model (BSPWB) has been proposed as an alternative to the Bulk Synchronous Parallel (BSP) model for the analysis, design and prediction of asynchronous MPI programs. This work compares the prediction accuracy of the BSP and BSPWB models and the performance

A Standard Interface for Debugger Access to Message Queue Information in MPIof the MPI message queues. The design has been implemented in the TotalView debugger, and dynamic libraries that conform to the interface exist for MPICH, as well as the proprietary MPI implementations from Compaq, IBM, and SGI.

Towards Portable Runtime Support for Irregular and Out-of-Core Computationss for handling irregular data were developed using the same concept as in the CHAOS library. Out-of-core parallelization is based on the idea of ., and functions for out-of-core data are implemented with capabilities provided by MPI-IO. The new library may be used in C, Fortran and Java programs. Re

Enhancing the Functionality of Performance Measurement Tools for Message Passing Environments- in order to adapt them to work with message passing applications. We discuss the concepts of porting the tools to the OCM monitoring environment, the structure of the modified tools and the extensions made, as well as implementation issues.

Efficient Replay of PVM Programsroblem of nondeterminism in distributed system and proposes an efficient approach to trace a PVM application behaviour in order to eliminate races in repetited execution. Detecting races in distributed computations requires implementation of a strongly consistent system of vector clocks. Therefore a
