This tutorial presents state-of-the-art tools for engineering performant parallel applications on computer clusters with MPI and/or OpenMP. The suite of tools developed by the Virtual Institute for High Productivity Supercomputing (VI-HPS) are introduced, including Scalasca, Vampir and Periscope. The tools support automated and manually-customizable measurement and analyses with hardware counter metrics as well as communication and synchronization overheads. A series of hands-on exercises are included which participants are encouraged to follow on their notebook computers using a provided Live-DVD with a bootable typical HPC cluster Linux environment. This will offer practical experience using the tools and help prepare participants to apply modern methods for locating and diagnosing performance bottlenecks in real-world parallel applications up to the largest scales.
This full-day tutorial will:
- give an overview of the VI-HPS programming tools suite
- explain the functionality of individual tools, and how to use them effectively
- offer hands-on experience using the tools with a LiveDVD
|Day 1||Friday 24th September|
|08:30||(registration & set-up of notebook computers)|
|09:00||Welcome & Introduction [Wylie, JSC]
|09:45||Introduction to parallel application engineering [Gerndt, TUM]|
|11:00||Scalasca performance analysis toolset
|14:00||Vampir performance analysis toolset

Participants are expected to use their own notebook computers for the tutorial using a Live-DVD provided by us for hands-on exercises: it may be possible to arrange alternatives for those who don't have access to an x86-compatible notebook computer with DVD drive, if the organizers are informed in advance.
Further information and registration
Tutorial participation is included with registration for IEEE Cluster 2010, which must be done on the conference website.
