AN ENVIRONMENT FOR THE DESIGN AND PERFORMANCE
EVALUATION OF PORTABLE PARALLEL SOFTWARE
by Jamal Zemerly
Centre for Parallel Computing, U. of Westminster
-----------------------------------------------
Abstract:
A major obstacle to the widespread adoption of parallel computing
in industry is the difficulty in program development due mainly
to lack of parallel programming design tools. In particular,
there is a need for performance-oriented tools, and especially
for clusters of heterogeneous workstations, to allow the software
designer to choose between design alternatives such as different
parallelisation strategies or paradigms.
An environment for performance-oriented design of portable
parallel software which has been developed at the Centre for
Parallel Computing, University of Westminster will be described.
The environment consists of a graphical design tool based on the
PVM communication library for building parallel algorithms,
a state-of-the-art simulation engine, a cpu characterisation tool,
a distributed debugging tool and a visualisation/animation tool.
The environment is used to model a virtual machine composed of
a cluster of workstations interconnected by a local area network.
The simulation model used is modular and its components are
interchangeable which allows easy re-configuration of the platform.
Preliminary experiments on a number of case studies showed
an average error between the real and the simulated results of
less than 10%. Future directions include developing an abstract
communication layer and a "design assistant" tool based on
"intelligent" performance analysis.
