Cori KNL: Programming and Optimization, Feb 12-13, 2019

NERSC will host a two-day training event for users on Cori KNL Programming and Optimization from Tuesday, February 12 to Wednesday, February 13. The first day of the training will be mostly presentations from Cray and NERSC staff, and the second day will be in the format of a hackathon that users can bring your own application codes and get hands-on help for KNL porting and optimization.
