NERSC continues to remain open while following site-specific protection plans. We remain in operation, with the majority of NERSC staff working remotely, and staff essential to operations onsite. We do not expect any significant changes to our operations in the next few months. You can continue to expect regular online consulting and account support as well as schedulable online appointments. Trainings continue to be held online. Regular maintenances on the systems continue to be performed while minimizing onsite staff presence, which could result in longer downtimes than would occur under normal circumstances. Because onsite staffing is so minimal, we request that you continue to refrain from calling NERSC Operations except to report urgent system issues. For **current NERSC systems status**, please see the online [MOTD](https://www.nersc.gov/live-status/motd/) and [current known issues](https://docs.nersc.gov/current/) webpages. ([back to top](#top)) --- ## This Week's Events and Deadlines <a name="section2"/></a> ## ### Application Deadline for December NERSC GPU Hackathon Extended to Friday! <a name="hackathon"/></a> NERSC, in conjunction with the OpenACC Organization, NVIDIA and OLCF, will be hosting a GPU Hackathon from December 7th-9th with an opening day on December 1st as part of the annual [GPU Hackathon Series](https://gpuhackathons.org/)! This year, NERSC is holding two hackathons to help accommodate the great interest in our first hackathon, and to prepare the community to run on new and upcoming GPU supercomputers, such as Summit, Perlmutter and Frontier. Accepted teams will be able to use [Perlmutter](https://www.nersc.gov/systems/perlmutter/), NERSC's new NVIDIA A100-based supercomputer, during the hackathon (outage and maintenance permitting). The hackathon is virtual and we highly encourage Open Science teams that are in the process of porting to GPUs to [apply](https://www.gpuhackathons.org/event/nersc-gpu-hackathon-2021). Teams should consist of three or more developers who are intimately familiar with the relevant parts of their application. They will work alongside mentors with GPU programming expertise relevant to their needs. If you want/need to get your code running/optimized on a GPU-accelerated system, these hackathons offer a unique opportunity to set aside 4 days, surround yourself with experts in the field, and achieve great strides toward your development goals. If you are interested in more information, or would like to submit a short proposal form, please visit the GPU Hackathon's event page: <https://www.gpuhackathons.org/event/nersc-december-gpu-hackathon-2021> or NERSC's event page: <https://sites.google.com/lbl.gov/gpuhackathon-dec2021>. Please note that the deadline to submit a proposal is **midnight this Friday, October 15th, 2021**. If you have any questions, please feel free to contact Kevin Gott (<kngott@lbl.gov>). ### IDEAS-ECP Webinar on Migrating to Heterogeneous Computing on Wednesday <a name="ecpwebinar"/></a> The next webinar in the [Best Practices for HPC Software Developers](http://ideas-productivity.org/events/hpc-best-practices-webinars/) series is entitled "Migrating to Heterogeneous Computing: Lessons Learned in the Sierra and El Capitan Centers of Excellence" and will take place **this Wednesday, October 13, 2021, at 10:00 am Pacific time.** In this webinar, David Richards (Lawrence Livermore National Laboratory) describes the role of the Sierra Center of Excellence in bringing experts from IBM and NVIDIA together with LLNL in a concentrated effort to prepare applications, system software, and tools for the Sierra supercomputer. A new COE for preparing for El Capitan is underway with HPE and AMD. The speaker will describe the operation of these COEs and share lessons learned, with the hope that others will be able to learn from both their successes and intermediate setbacks. There is no cost to attend, but registration is required. Please register [here](https://www.exascaleproject.org/event/sierra_and_elcapitan_coe/). ### CUDA Graphs Training, This Wednesday <a name="cutrain"/></a> As a continuation of last year's popular [CUDA Training Series](https://www.olcf.ornl.gov/cuda-training-series/), NVIDIA will present a session on "CUDA Graphs" to NERSC and OLCF users **this Wednesday, October 13, 2021,** from 10 am to noon (Pacific time). CUDA graphs are a model for work submission to GPUs in CUDA that help improve the latency associated with submitting work to the GPU. A graph is a series of operations (e.g., kernel launches) connected by dependencies, which are defined separately from their execution, allowing a graph to be defined once and then launched repeatedly. Separating the definition of the graph from its execution enables optimizations that reduce the cost of launching and executing work on the GPU. This presentation will demonstrate how to use CUDA graphs in an application and discuss the circumstances under which speedup may be obtained, followed by hands-on example exercises. Homework will be provided to reinforce the concepts learned in the session. NERSC will provide access to its Cori-GPU system for current NERSC users. Registration is required for remote participation. For more information and to register please see <https://www.nersc.gov/users/training/events/cuda-graphs-october-13-2021/> ### Learn to Use Spin to Build Science Gateways at NERSC: Next SpinUp Workshop Starts Thursday! <a name="spinup"/></a> Spin is a service platform at NERSC based on Docker container technology. It can be used to deploy science gateways, workflow managers, databases, and all sorts of other services that can access NERSC systems and storage on the back end. New large-memory nodes have been added to the platform, increasing the potential of the platform for new memory-constrained applications. To learn more about how Spin works and what it can do, please listen to the NERSC User News podcast on Spin: <https://anchor.fm/nersc-news/episodes/Spin--Interview-with-Cory-Snavely-and-Val-Hendrix-e1pa7p>. Attend an upcoming SpinUp workshop to learn to use Spin for your own science gateway projects! Applications for sessions that begin this [Thursday October 14](https://www.nersc.gov/users/training/spin/) are still open. SpinUp is hands-on and interactive, so space is limited. Participants will attend an instructional session and a hack-a-thon to learn about the platform, create running services, and learn maintenance and troubleshooting techniques. Local and remote participants are welcome. If you can't make these upcoming sessions, never fear! The next session begins December 9, and there are more planned for 2022. See a video of Spin in action at the [Spin documentation](https://docs.nersc.gov/services/spin/) page. ([back to top](#top)) --- ## Perlmutter <a name="section3"/></a> ## ### Perlmutter Machine Status <a name="perlmutter"/></a> The initial phase of the Perlmutter supercomputer is in the NERSC machine room, booting and running successfully. We continue configuring and testing the machine. Updated operating system and user environments have been installed on Perlmutter. We are beginning to allow friendly users onto the machine. We hope to add even more users soon. This newsletter item will be updated each week with the latest Perlmutter status. ### Perlmutter Availability Access Plan <a name="pmaccess"/></a> NERSC is continuing to configure and test Perlmutter in preparation for opening the system to the broader NERSC community. We are working with a small number of application partners to identify issues and test the programming and runtime environments. Once the system is ready, users will be added in stages beginning with early-access users. ### (NEW) Prepare Your Dotfiles for Perlmutter! <a name="dotfiles"/></a> To help ready your account for Perlmutter, please review your dotfiles. The same home file system is mounted across all NERSC systems, so your `.bashrc`/`.cshrc`/etc. files (dotfiles) need to work on all systems. The NERSC\_HOST variable can help you distinguish between systems and to set customizations for each system. The NERSC\_HOST variable is set automatically to "perlmutter" on Perlmutter and to "cori" on Cori. Some users may have older dot files that are setting the NERSC\_HOST variable without first checking to see whether it already has a value, which will cause problems on Perlmutter. Please ensure that this is not the case in your dotfiles. Feel free to reach out to [NERSC consulting](https://help.nersc.gov) with any questions or issues. ([back to top](#top)) --- ## Updates at NERSC <a name="section4"/></a> ## ### Save the date: NUG Annual Meeting Thursday 21 Oct starting 8:30am PT <a name="nug"/></a> This year's NUG Annual Meeting will be entirely virtual and is scheduled for October 21, 2021, beginning at 8:30am Pacific Time.
