[Users] KNL Office Hours Starting in an Hour!

Dear NERSC Users, I encourage you to (virtually) attend the final KNL office hours of this month, which are starting in about an hour. During the office hours, which run until 3 pm Pacific Time, NERSC experts will be on hand to help you with setting up your job script for proper thread affinity, compiling your code with the best optimization flags, getting started with profiling your code, and interpreting the results of profiling plus advice on next steps. KNL nodes outnumber Haswell nodes on Cori by a large margin, so you are likely to get your results faster via the KNL queues, even if the job itself takes more time to run. We can help you narrow that performance gap, and in some cases, get better performance on KNL. In addition, any steps you take to improve performance on KNL are likely to be beneficial for Perlmutter (even on the CPU-only nodes). The full Zoom invitation is attached to this email. We look forward to seeing you there! Regards, -Rebecca Rebecca Hartman-Baker is inviting you to a scheduled Zoom meeting.
