Dear NERSC Users, Welcome back from summer break! Now is a great time to run jobs at NERSC and avoid the end-of-the-year crunch when queues are extremely long and job turnaround time is slow. Using your time now benefits the entire NERSC community and spreads demand more evenly throughout the year, so to encourage usage now, we are discounting all jobs run on the Perlmutter GPU nodes by 50% starting *tomorrow* and through the end of September. Any job (or portion of a job) that runs between midnight tonight and the very start of October 1 at midnight (Pacific time), will be charged only half the usual charges, e.g., a 3-hour job on 7 nodes, which would normally incur a charge of 21 GPU node-hours, would be charged 10.5 GPU node-hours. Are there roadblocks preventing you from getting started on Perlmutter’s GPU nodes? Are you interested in using the GPU nodes but concerned about inefficiently using your allocation? Did you get bad performance before and need some help making sure your script is set up correctly? Do you want to try out a new GPU-enabled code but aren’t sure where to start? We are offering additional help to users through Perlmutter GPU Virtual Office Hours <https://www.nersc.gov/users/training/events/2023/perlmutter-gpu-office-hours-sept/>, beginning this coming Monday, September 11, from 9-11 am (Pacific time). Drop in anytime during the period with your questions on all things Perlmutter GPU: compiling, job scripts, job profiling, and more! Can’t make it on Monday? Additional office hours are scheduled for September 18, and 25, and October 5 and 11. Thanks for being a NERSC user, and as usual, feel free to send in a ticket <https://help.nersc.gov> with any questions!
