Automatic scalability analysis of parallel programs based on modeling techniques [chapter]

Allen D. Malony, Vassilis Mertsiotakis, Andreas Quick
1994 Lecture Notes in Computer Science  
When implementing parallel programs for parallel computer systems the performance scalability of these programs should be tested and analyzed on different computer configurations and problem sizes.  ...  We present several computation classes where tractable graph models can be generated and then compare the results of these automatically scaled models with their exact solutions using the PEPP modeling  ...  Automatic Scalability Analysis with the Tool PEPP PEPP (Performance Evaluation of Parallel Programs) [4] is a modeling tool for analyzing stochastic graph models.  ...

First Passage Time Analysis of Stochastic Process Algebra Using Partial Orders [chapter]

Theo C. Ruys, Rom Langerak, Joost-Pieter Katoen, Diego Latella, Mieke Massink
2001 Lecture Notes in Computer Science  
Our approach is supported by the (new) tool Forest for generating the complete prefix and the (existing) tool Pepp for analysing the generated task graph.  ...  This paper proposes a partial-order semantics for a stochastic process algebra that supports general (non-memoryless) distributions and combines this with an approach to numerically analyse the first passage  ...  Acknowledgements We want to thank Markus Siegle from the University of Erlangen for kindly giving us permission to use the Pepp tool.  ...
