Overview
Both the DOE-supported NCCS and and the NSF-supported NICS have installed new Cray XT5 systems. These powerful supercomputer systems have features which must be well understood by developers and users to enable large applications to scale to higher number of processors and achieve sustained higher performance.
NCCS and NICS will jointly sponsor a 4 day workshop covering the important issues in obtaining increased performance. In particular the following topics with be covered:
- XT5 architecture
- XT5 NUMA issues
- Programming effectively for the XT5
- Using OpenMP on the multicore XT5
- Optimizing MPI performance on the Seastar II Interconnect
- Latest Libraries for the Quad cores
- Using the latest Craypat to identify application bottlenecks
- Strategies for improving algorithmic scaling
This workshop will have lectures from NCCS, NICS and Cray staff as well as hands-on sessions, where the staff will be available to work on your application with you. Past workshop have been extremely successful and you are encouraged to attend to get the most out of the fastest computers in the world.
