COMPUTER SYSTEM AND METHOD FOR ANALYSING THE PERFORMANCE OF AN APPLICATION MAKING CALLS FOR COMMUNICATION FUNCTION BETWEEN A PLURALITY OF PROCESSES

摘要

A computer system and method for performance analysis of an application providing communication function calls between multiple processes, including an application for performance analysis and mapping of inter-process communications in a computer application in a parallel and distributed computing environment.The method comprises a step of collecting information relating to the function calls, a call or a succession of at least two calls forming a pattern 7 to 11, and a step of compressing collected.The compression step comprises: - a step of detecting, from the collected information, patterns 7 to 11 and successions of patterns 7 to 11, to form a grammar in which each pattern 7 to 11 and each succession of patterns 7 to 11 are identified by a unique identifier, - a step of detection, in grammar, of the repetition of patterns 7 to 11 and successions of patterns 7 to 11, - a step of generating a compressed trace file in which are stored the patterns 7 to 11 and the successions of patterns 7 to 11, and their respective numbers of repetition 12 to 15.
