Performance prediction allows to evaluate programs for a hypothetical machine. it is based on: benchmarking determines the performance of a computer system on the basis of a set of typical applications. more precise dependence analysis might unveil more parallelism.

Parallel Performance Analysis Rc Learning Portal Hence, modeling and analyzing performance are pre requisites for writing efficient parallel programs. this chapter discusses a few abstract models of computation, which can be used to express and analyze parallel algorithms. The first is in an abstract setting, for example, the asymptotic analysis of the underlying algorithm. the second is concrete – how well does the algorithm's implementation behave in practice on the available hardware and on data sizes of interest. Does a parallel program run faster than its sequential version? what are the cost to enable parallelism? tall= p tp (pis the number of processors). what is the benefit from increasing parallelism?. Introduction analysis of execution time for parallel algorithm to dertmine if it is worth the effort to code and debug in parallel understanding barriers to high performance and predict improvement goal: to figure out whether a program merits parallelization.

Parallel Programming Course description: parallel programming models; sequential and parallel performance issues; high performance computer architecture; design, analysis, implementation and performance evaluation of parallel algorithms. Efficiency is a measure of process utilitization in a parallel program, relative to the serial program. for a reasonable estimatation of the performance of a parallel program, we should count also the cost of communication. Suppose 95% of a program’s execution time occurs inside a loop that can be executed in parallel, and this is the only parallelizable part of the code. what is the maximum speedup we should expect from a parallel version of the program executing on 8 cpus? what is the efficiency? what is the maximum theoretical speedup? in this case f = 0.05. Performance analysis and tuning: techniques for profiling and optimizing parallel programs are discussed, including identifying bottlenecks and improving communication efficiency. we provide a hands on approach to performance analysis using profiling tools. iv. case studies and applications:.
