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> ## ### Join Us for the NUG Annual Meeting this Thursday, 21 Oct starting 8:30am PT <a name="nug"/></a> This year's NUG Annual Meeting begins this Thursday October 21, 2021, at 8:30am Pacific Time. The final agenda for the meeting is available at <https://www.nersc.gov/users/NUG/annual-meetings/nug-2021>. There's still time to register at <https://forms.gle/JQN15SUoEMSdJK286> (<https://www.nersc.gov/users/NUG/annual-meetings/nug-2021> also has a link to the form). There is no cost to register. We look forward to seeing you there! ([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. ### 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> ## ### (NEW) NERSC Annual Report and User Demographics Now Available Online! <a name="annualrep"/></a> The [NERSC 2020 Annual Report](https://www.nersc.gov/assets/Uploads/NERSC-2020-Annual-Report-Final.pdf) (pdf) is now available online. Learn about NERSC's response to the unique circumstances of 2020, our major milestones for the year, and some highlights from our users' accomplishments. Check out our [2020 User Demographics](https://www.nersc.gov/assets/Uploads/NERSC-User-Demographics-2020.pdf) as well. ### Apply for Prestigious Alvarez & Hopper Fellowships in Computing Sciences at Berkeley Lab & NERSC by November 22 <a name="alvarezhopper"/></a> Are you about to earn your PhD in a computational science discipline or have you earned it within the past three years? Are you looking for a position in which you can set your own research agenda within the broad computing science field? Consider applying for the 2022 Luis W. Alvarez Postdoctoral Fellowship or the 2022 Admiral Grace Hopper Postdoctoral Fellowship in the Computing Sciences Area at Berkeley Lab! The [Luis W. Alvarez fellowship](https://cs.lbl.gov/careers/computing-fellowships/alvarez-fellowship/), established in 2002, offers challenging research opportunities in the development of computational methods and tools for scientific discovery. Fellows apply the latest technologies to computational modeling, simulations, and advanced data analysis for scientific discovery in materials science, biology, astronomy, environmental science, energy, particle physics, genomics, and other scientific domains. The [Admiral Grace Hopper Fellowship](https://cs.lbl.gov/careers/computing-fellowships/hopper-fellowship/) was established in 2015 with the goal of developing early-career computational scientists to make outstanding contributions in the area of HPC applications. Applicants should have expertise with advanced algorithms, software techniques, HPC systems, and/or networking in a related research field. Applications to both fellowships are made jointly by a single process. For more information and to apply, please see the [position listing](http://m.rfer.us/LBLq6B4Aw). Applications close on November 22, 2021. ### Join Us for the NERSC Early Career Achievement Award Seminar Series, Wednesdays through November 17 <a name="ecawseminar"/></a> NERSC is hosting a seminar searies featuring the recipients of the NERSC Early Career Achievement Awards on Wednesdays at noon (Pacific time) starting Wednesday, September 22, and running through November 10. The talk originally scheduled for this week **has been postponed**. Stay tuned next week for another talk. For more information on the series and links to join the event, please see <https://www.nersc.gov/science/nersc-hpc-achievement-awards/achievement-award-seminar-series/>. All talks will be recorded and posted to [NERSC's YouTube channel](https://www.youtube.com/c/NERSCTraining-HPC). ### E4S Version 21.05 Now Available on Cori! <a name="e4s"/></a> We are pleased to announce that the E4S version 21.05 software stack compiled with the Intel version 19.1.3.304 compiler is now available on Cori. E4S (the Extreme-scale Scientific Software Stack) provides popular HPC products including programming models, development tools, math libraries, and data and visualization tools. The E4S 21.05 stack on Cori includes several new packages, including amex, parallel-netcdf, scr, vtk-m, py-warpx, warpx, metall, and mpark-variant. The E4S 21.05 stack can be accessed by running `module load e4s/21.05`, which sets up a Spack environment with the available software stack. Module names are easy to type and do not contain hashes. For more information, including a complete list of all available packages, please see <https://docs.nersc.gov/applications/e4s/cori/21.05/>. Please use the NERSC [Help Desk](https://help.nersc.gov) to file a ticket with any questions or concerns.

Jean Shuler (Lawrence Livermore National Laboratory) has worked at the leading edge of HPC for 5 decades. This webinar will be a Q&A on the fascinating career of a woman who taught herself programming on the job at NASA Langley beginning in 1963, and found her way to Lawrence Livermore National Laboratory by 1972, sparking a long career helping others to find their way in HPC. Jean created and led the User Services program at NERSC (then housed at LLNL). When NERSC moved to Berkeley Lab in 1996, Jean applied her passion and experience to support the ASCI program users at Livermore Computing. If you yave an interest in computing history, the experiences and impact of women in computing, or if you are early in your career and looking for inspiration, you will want to attend this webinar and listen to Jean's amazing stories and ask her some questions! There is no cost to attend, but registration is required. Please register [here](https://www.exascaleproject.org/event/55plus-years-in-hpc/).
