Description of the training

Full day training on optimizing your application for Cori Phase 2 including a significant hands-on time with your own applications.

Attendees will learn about the Cray Performance Tools available for identifying performance bottlenecks and optimization opportunities within an HPC program. This session includes training on how to collect application performance information, tips on interpreting data in reports, and where to focus optimization efforts. The training will include how to identify performance bottlenecks such as load imbalance. Attendees will also learn how to use Reveal to identify and parallelize performance critical loops within a program.

Presentations will cover how to use CrayPat-lite, get optimization feedback from the Cray compiler (listings, Reveal), study performance data (imbalance, MPI rank reorder, etc.), look for OpenMP opportunities and use Reveal, look for vectorization opportunities, understand cache/memory access in preparation for KNL with CrayPat

During hands on time, users will use CCE (including generating loop mark, program library)

CrayPat-lite, CrayPat and Reveal.
