JURECA Porting and Tuning Workshop

In the past few years, JSC has been running Porting and Tuning Workshops on its highly scalable Blue Gene/Q system JUQUEEN. This year’s workshop will cover the latest system in Jülich, the new general-purpose cluster JURECA. As the successor to the apparently similar JUROPA system, JURECA is at first as easy to use. The increased complexity of the system, however, requires special attention to multi-threading and vectorization to achieve peak performance.

The workshop will take place on 6-8 June 2016. The topics will include best practices for JURECA, possibilities of visualization, and scientific big data analytics. We will also cover efficient I/O and ways to achieve multi-threading and vectorization as well as GPU programming. Special emphasis will be placed on node-level performance and performance analysis.

At the heart of the workshop will be extensive hands-on sessions with the participants’ codes, aimed at helping with porting applications to JURECA and understanding performance bottlenecks. After the workshop, participants should have their codes running on JURECA and a clear picture of how to further improve performance. The event will be supervised by members of staff from JSC’s Simulation Laboratories and the cross-sectional teams Application Optimization, Performance Analysis, Visualization and Mathematical Methods and Algorithms.
