HOWTO: Collect performance data for your program

This page outlines ways to generate and view performance data for your program using tools available at OSC.

Intel Tools

This section describes how to use performance tools from Intel. Make sure that you have an Intel module loaded to use these tools.

Intel VTune

Intel VTune is a tool to generate profile data for your application. Generating profile data with Intel VTune typically involves three steps:

Desmond

Desmond is a software package that perform high-speed molecular dynamics simulations of biological systems on conventional commodity clusters, general-purpose supercomputers, and GPUs. The code uses novel parallel algorithms and numerical techniques to achieve high performance and accuracy on platforms containing a large number of processors, but may also be executed on a single computer. Desmond includes code optimized for machines with an NVIDIA GPU.
