Overview

Questions

  • What are other patterns of performance bottlenecks?
  • How to evaluate an application in more detail?

Objectives

After completing this episode, participants should be able to …

  • Find collection of performance patterns on hpc-wiki.info
  • Identify next steps to take with regard to performance optimization.

Narrative:

  • Start with picture of beautiful title slide of the talk with the snowman picture
  • Next time we want to tackle the issue way in advance
  • Approach our raytracing application more systematically, such that we can get the title slide done much quicker
  • What could we do to dive deeper in optimizing the raytracer?
  • Where can we go from here?

What we’re doing here:

  • Learning important programming concepts (parallel programming on many levels)
  • Deeper application profiling & tools to use

Next Steps

hpc-wiki.info - I/O - CPU Front End - CPU Back End - Memory leak - Oversubscription - Underutilization

Summary

Key Points
  • There are many profilers, some are language-specific, others are vendor-related, …
  • Simple profile with exclusive resources
  • Repeated measurements for reliability
