SVMview: a Performance Tuning Tool for DSM-based Parallel Computers
Abstract
This paper describes a performance tuning tool, named SVMview, for DSM-based parallel computers. SVMview is a tool for doing a post-mortem analysis of page movements generated during the execution of Fortran-S programs. This tool is able to analyze some particular phenomena such as false-sharing which occurs when several processors write to the same page simultaneously. Such behavior entails badly the performance of DSM systems, and thus are particularly important to be detected.
