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

Within the efforts of DKRZ to support its users in the efficient use of its supercomputing systems, DKRZ offered a Program Analysis and Tuning Workshop on the 5th and 6th of August 2013 at DKRZ in Hamburg. It was organized by the DKRZ team together with experts in tool-development from the Jülich Supercomputing Centre and from TU Dresden.

The workshop with about 25 attendees focused on enhancements in the performance of user's real world applications by hands on profiling and tracing of the codes with program analysis and tracing tools. The users had the chance to see the complete workflow of using performance analysis tools and the benefits of it.  Moreover, problems using these tools could be discussed directly with the tool developers in order to obtain solutions and a valuable feedback for the performance improvements of the applications.

The workshop slides are available for download via the DKRZ User Portal.
