Trace-Based Parallel Performance Overhead Compensation
Abstract. Tracing parallel programs to observe their performance introduces intrusion as the result of trace measurement overhead. If post-mortem trace analysis does not compensate...

DIMVisual: Data Integration Model for Visualization of Parallel Programs Behavior
Abstract-- The development of high performance parallel applications for clusters is considered a complex task. This can happen because the influence of the execution environment a...

Automatic Experimental Analysis of Communication Patterns in Virtual Topologies
Automatic pattern search in event traces is a powerful method to identify performance problems in parallel applications. We demonstrate that knowledge about the virtual topology, ...

Specification of Inefficiency Patterns for MPI-2 One-Sided Communication
Abstract. Automatic performance analysis of parallel programs can be accomplished by scanning event traces of program execution for patterns representing inefficient behavior. The ...
