Overview

Vampir is an established performance tool for visualizing and analyzing the behavior of highly parallel HPC applications. It is supported by the Score-P tool, which can be used to fully record the runtime behavior of HPC applications. Especially when using several parallel programming paradigms or shared HPC resources (I/O), this offers a detailed insight into the application. This workshop introduces the use of Vampir and Score-P for the interactive and visual analysis of the runtime behavior of HPC applications.

Day one will feature lessons and hands on exercises. The second day will give users an opportunity to bring their own codes and instrument them for performance analysis with help from Score-P and Vampir developers. To take advantage of this you must have a code that is already compiled and working on Frontier. You may register for one or both days. Please list your code and a goal for the 2^nd day on the registration form if you plan to attend that day.

Prerequisites:

• You are an OLCF user with access to Frontier
• Knowledge of Compiling and running parallel applications (any of MPI, OpenMP, HIP, CUDA) from the command line prompt
• Knowledge of modifying source code on the command line prompt

You will have the opportunity to learn how to:

• Apply a performance engineering cycle to a parallel program
• Reduce overhead caused by instrumentation
• Find typical performance bottlenecks via visual analysis
