"HPC Tools for Performance Profiling and Analysis on Some Code Examples"

DATE: August 26, 2009 to August 26, 2009
TIME: 10:30 AM - 11:30 AM
SPEAKER: Dr. John Romo, Applications Engineer, (formerly of SciCortex, Inc.)
LOCATION: Building 360 / Conference Room L119, Argonne National Labortory

Description:
Programmers and application developers using HPC systems require simple-to-use tools to determine how efficiently their codes are executing on a target machine, and for analysis and eventual improvement of their application’s performance.

Many factors contribute to an application’s performance on HPC systems. Extracting meaningful runtime performance data, managing very large performance data volumes, extracting useful information from them, interpreting that runtime information to identify and locate those factors, which most affect performance, are all tasks difficult for a programmer to manage. Tools to extract and record system events indicative of execution performance have been available for some time. What has been lacking is a means to manage, reduce complexity, and extract hidden execution performance problems.

A performance tool set, from a recent system vendor, based on existing performance packages like PAPI cross-platform hardware performance counter interface, developed at the University of Tennessee, TAU (Tuning Analysis and Utilities) performance tool suite, developed at the University of Oregon, and others, is used to illustrate runtime performance inefficiencies in example codes.
