([back to top](#top)) --- ## Perlmutter <a name="section3"/></a> ## ### Perlmutter Machine Status <a name="perlmutter"/></a> Perlmutter is available to all users with an active NERSC account. Some helpful NERSC pages for Perlmutter users: * [Perlmutter queue information](https://docs.nersc.gov/jobs/policy/#qos-limits-and-charge) * [Timeline of major changes](https://docs.nersc.gov/systems/perlmutter/timeline/) * [Current known issues](https://docs.nersc.gov/current/#perlmutter) This section of the newsletter will be updated regularly with the latest Perlmutter status. ### Prepare Now for Transitioning to Perlmutter from Cori! <a name="pmprep"/></a> With Cori scheduled to be retired on May 31, it is a good time to make sure that you are prepared to transition your workflows to Perlmutter. NERSC is here to help -- we have prepared a [Cori to Perlmutter migration webpage](https://docs.nersc.gov/systems/cori/migrate_to_perlmutter/) and provided several trainings recently that will be beneficial to current users looking to transition to Perlmutter, with more events in the works: - September's [New User Training](https://www.nersc.gov/users/training/events/new-user-training-sept2022/) contained lots of useful information about Perlmutter and how to use it. Slides are available and professionally captioned videos are linked from the training webpage. - The [GPUs for Science Day](https://www.nersc.gov/users/training/events/gpus-for-science-day-2022-october-25th/) (slides and videos with professional captions available) contained valuable resources for those migrating their applications to Perlmutter GPUs. - The [Data Day](https://www.nersc.gov/users/training/events/data-day-2022-october-26-27/) event (slides and videos currently available) included content aimed at users who are interested in porting their data workflows to Perlmutter. - The [Migrating from Cori to Perlmutter](https://www.nersc.gov/users/training/events/migrating-from-cori-to-perlmutter-training-dec2022/) training, which took place on December 1, focused on building and running jobs on Perlmutter. The slides and videos with professional captions from this training have been published on the event webpage. A repeat training with minor updates was offered on [March 10](https://www.nersc.gov/users/training/events/migrating-from-cori-to-perlmutter-training-march2023/). - Attend [Cori to Perlmutter Transition Office Hours](#c2poh) this month to get one-on-one help from an expert on transitioning to the new Perlmutter machine. ### (NEW/UPDATED) Scratch Purging on Perlmutter Begins in June <a name="pmscratch"/></a> The purpose of the scratch file systems attached to large NERSC supercomputing resources like Perlmutter and Cori is to provide a temporary storage space for user jobs to use while running. A scratch file system is less of a file system for storing files and more of a temporary space for data. Given this, NERSC has scratch purge policies in place, where NERSC reserves the right to remove old files from the scratch system to free up space. Starting at a date to be determined in June, NERSC will begin applying the scratch purge policy to Perlmutter's scratch file system. The precise date the policy goes into effect will be announced at least two weeks beforehand in a standalone email from NERSC. At that point, any files older than 8 weeks may be deleted from the scratch file system. For more information on NERSC file systems and scratch purge policies, please see <https://docs.nersc.gov/filesystems/quotas/>. ([back to top](#top)) --- ## Updates at NERSC <a name="section4"/></a> ## ### Cori Retirement Date Approaching: May 31st at Noon <a name="coriretireC"/></a> Cori is scheduled to be **retired in just over one week, next Wednesday, May 31, 2023 at noon PDT.** NERSC system administrators have put in place a reservation that will prevent any jobs from running past 12:00 noon on May 31. Users will still be able to log into the Cori login nodes and access the Cori scratch file system for one week, until Wednesday, June 7, 2023. At that time, the system will be powered down and prepared for removal. We encourage any users still primarily using Cori to migrate your workflows as soon as possible. This month, NERSC is holding an additional series of [virtual office hours](#c2poh) with a focus on transitioning from Cori to Perlmutter. The purpose of the office hours is to enable users to receive one-on-one assistance from NERSC staff on enabling their codes and workflows on Perlmutter. Typical questions include compiling code, leveraging GPUs, writing scripts, and more.
