P3T+: A performance estimator for distributed and parallel programs
Developing distributed and parallel programs on today’s multiprocessor architectures is still a challenging task. Particular distressing is the lack of effective performance tools that support the programmer in evaluating changes in code, problem and machine sizes, and target architectures. In this paper we introduce P 3T+ which is a performance estimator for distributed and parallel programs. ...
متن کاملP3T: An Automatic Performance Estimator for Parallel Programs
The area of parallelizing compilers for distributed memory multicomputers has seen considerable research activity during the last few years. Most of the current compilers do not provide any support for estimating performance impacts of code changes that they apply. In this paper, we present P 3 T, which is a static and automatic performance estimator for data parallel programs. It computes at c...

متن کاملOn estimating the useful work distribution of parallel programs under P3T: a static performance estimator
In order to improve a parallel program's performance it is critical to evaluate how even the work contained in a program is distributed over all processors dedicated to the computation. Traditional work distribution analysis is commonly performed at the machine level. The disadvantage of this method is that it cannot identify whether the processors are performing useful or redundant (replicated...
متن کاملA Performance Estimator for Parallel Programs
In this paper we describe a Parallel Performance Estimator suitable for the comparative evaluation of parallel algorithms. The Esti-mator is designed for SPMD programs written in either C or FORTRAN. Simulation is used to produce estimates of execution times for varying numbers of processors and to analyse the communication overheads. Results from the estimator are compared with actual results ...
