Abstract

The goal of the project is the development of performance prediction techniques
for parallel systems of all  kinds and tuning the performance of parallel
applications running on real machines. Prediction techniques are to be developed
both for message passing as well as shared memory architectures and built upon
the calculus of communicating sequential processes (CSP), which yields the most
concise description if compared to other tools (like Petri nets, CCS,
communicating X-machines, etc.). The project aims at utilization of CSP-based
simulation tool Transim used world-wide in the widest possible spectrum of real
and realistic SW/HW architectures. The main results are expected in performance
prediction and tuning in digital signal and image processing, discrete
optimization, and in solution of large dense and sparse systems of linear
equations. Parallel platforms relevant for this project are clusters of 
workstations and PCs, symmetrical multiprocessors SMP and DSP-based embedded
parallel systems including chip multiprocessors and complete Systems on Chip
(SoC). Prediction-based  performance  tuning will lead to the fast comparison of
various multiprocessor HW/SW architectures  and promising alternatives will then
be coded (in MPI or OpenMP for portability) and put under the real test . The
project will also address  a difficult issue of fair performance comparison of
entirely different parallel systems, methods of load balancing, and reduction of
communication and synchronization overhead.
