Program Analysis and Tuning Workshop August 5./6., 2013

Within the efforts of DKRZ to support its users in the efficient use of its supercomputing systems, we offer a Program Analysis and Tuning Workshop on 5th and 6th of August 2013 at DKRZ in Hamburg. It is organized by the DKRZ team together with experts in tool-development from the Jülich Supercomputing Centre and from TU Dresden.
Aug 05, 2013 to Aug 07, 2013 (Europe/Berlin / UTC200)
DKRZ, Bundesstraße 45a, 20146 Hamburg

The focus of this workshop is to enhance the performance of user's real world applications by hands on profiling and tracing of the codes with program analysis and tracing tools. During this, the user will have the chance to see the complete workflow of using performance analysis tools and the benefits of it. Moreover, upcoming problems when using these tools can be discussed with the tool developers in order to get solution and valuable feedback for the performance improvements of the applications.

Basic requirement is that participants have knowledge about parallel programming with MPI and/or OpenMP. Furthermore, it is desired that users have an application running on IBM Power6 cluster "blizzard" at DKRZ, which they want to analyze with respect to performance optimization.

Every participant has to bring his/her own laptop. In total we can accommodate up to 25 attendees. First come, first served. If you are interested please register at:
