This year, the hackathon will be virtual and selected code teams will be able to test and develop on Perlmutter, and there is also the option to use an ARM system. **The deadline to submit a proposal has been extended to 11:59 PM Pacific, next Monday, June 5, 2023. Apply now!** Hackathons combine teams of developers with mentors to either prepare their own application(s) to run on GPUs or optimize their application(s) that currently run on GPUs. This virtual event consists of a kick-off day, where hackers and mentors video-conference to meet and develop their list of hackathon goals, as well as get set up on the relevant systems. This is followed by a one week preparation period before the 3-day intensive primary event. If you are interested in more information, or would like to submit a short proposal form, please visit the [GPU Hackathon event page](https://www.openhackathons.org/s/siteevent/a0C5e000005Va7IEAS/se000163) or [NERSC's event page](https://sites.google.com/lbl.gov/july-2023-gpu-hackathon/home). Questions can also be directed to NERSC's host, Hannah Ross (HRoss@lbl.gov). ### Memorial Day Holiday Today, May 29; No Consulting or Account Support <a name="memday"/></a> Consulting and account support will be unavailable **today, May 29**, due to the Berkeley Lab-observed Memorial Day holiday. Regular consulting and account support will resume tomorrow. ### Join Us Tomorrow for Final Cori to Perlmutter Office Hours Event in Series <a name="c2pohthisweek"/></a> Tomorrow, May 30, from 10 am to 12 noon (Pacific time), drop into NERSC's final Cori to Perlmutter transition virtual office hours with your questions for NERSC experts on migrating your applications and workflows from Cori to Perlmutter. For more information, including connection information (login required for Zoom link), please see <https://www.nersc.gov/users/training/events/migrating-from-cori-to-perlmutter-office-hours-may-2023/>. ### Training on Advanced SYCL Techniques & Best Practices Tomorrow! <a name="sycl"/></a> NERSC will host a virtual training event on advanced SYCL techniques and best practices tomorrow, May 30. The SYCL programming model means heterogeneous programming using C++ is now more accessible than ever. SYCL uses modern standard C++, and it's a programming model that lets developers support a wide variety of devices (CPUs, GPUs, FPGAs, and more) from a single code base. The growing popularity of this programming model means that developers are eager to understand how to use all the features of SYCL and how to achieve great performance for their code. While the tutorial assumes existing knowledge and some experince with using SYCL to develop code for accelerators such as GPUs, video recordings of more introductory SYCL trainings that may help prepare you for this training are available on [this YouTube playlist](https://www.youtube.com/playlist?list=PL20S5EeApOStYsTQ7AFkiIpPzuOBWo0jI). Concepts included in this training include strategies for optimizing code, managing data flow, how to use different memory acces patterns, understanding work group sizes, using vectorization, the importance of ND ranges, and making the most of the multiple devices available on your architecture. For more information and to register, please see <https://www.nersc.gov/users/training/events/advanced-sycl-techniques-and-best-practices-may2023/>. ### Cori Retirement Date Approaching: this Wednesday at Noon <a name="coriretireC"/></a> Cori is scheduled to be **retired in two days: this 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 next Wednesday, June 7, 2023. At that time, the system will be powered down and prepared for removal. ([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 retiring on Wednesday at noon, now 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/). ### 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> ## ### (NEW/UPDATED) Migrate Cori Cron Jobs to scrontab on Perlmutter <a name="cron"/></a> Some users require regularly scheduled tasks as part of their NERSC workflows. On Cori, these were provided through the cron functionality in Linux. On Perlmutter, however, this functionality is provided through the Slurm crontab tool called `scrontab`. This tool combines the same functionality as cron with the resiliency of the batch system. We encourage you to examine any crontab scripts that you may have in play on Cori, and convert them to `scrontab` on Perlmutter. For more information on `scrontab`, please see <https://docs.nersc.gov/jobs/workflow/scrontab/>.
