Under this Order, NERSC may continue to remain open while following site-specific protection plans. We remain in operation as before, with the majority of NERSC staff working remotely and only a skeleton crew onsite. During this period, you can continue to expect regular online consulting and account support but no telephone support. Trainings will continue to be held online, or postponed if online is infeasible. Regular maintenances on the systems will 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 refrain from calling NERSC Operations except to report urgent system issues. ### Potential Impacts on NERSC from California Wildfire Season <a name="pspswarn"/></a> PG&E, which provides power to Berkeley Lab (and NERSC), continues with its conservative approach to wildfire prevention this year: de-energizing transmission power lines in areas with acute wildfire risk. This practice may result in the power to the NERSC machine room being cut with little advance notice. During one of these events, NERSC will fall to generator power, which is not sufficient to power Cori, but will keep auxiliary, non-compute systems online. We will keep users informed about what's going on at NERSC, including any information about when we will come back online. Users can also consult <> to find out the latest status of NERSC as well as Berkeley Lab as a whole. Berkeley Lab was placed on a Public Safety Power Shutoff (PSPS) **watch** status for this evening through Wednesday morning. However, PG&E informed Lab emergency management leadership that **the Lab is not in one of the areas currently targeted for shutoff.** While this particular PSPS event is unlikely to affect NERSC, from September to early November there is a small but persistent chance of a PSPS event impacting NERSC on any given day. Based on last year's experience, NERSC may have less than 48 hours notice to shut down. We therefore recommend that users with time-sensitive tasks allow additional time to accommodate potential power outages, if possible. Users with long jobs (i.e., jobs exceeding 24 hours walltime) should be prepared for the risk of interruption. We recommend implementing [checkpointing]( for long jobs to assure that some progress can be saved from a PSPS disruption. If you have any questions about the potential impact of PSPS events on your work, please send in a ticket at <>. ([back to top](#top)) --- ## This Week's Events and Deadlines <a name="section2"/></a> ## ### Labor Day Holiday Today; No Consulting or Account Support <a name="laborday"/></a> Consulting and account support will be unavailable today, September 7 due to the Berkeley Lab-observed Labor Day holiday. Regular consulting and account support will resume tomorrow. Operations staff are available for urgent queries via 1-800-66-NERSC, Option 1, at all times. ### Apply for Sustainable Research Pathways Workshop 2020 by Friday! <a name="srp2021"/></a> Are you a full-time faculty member at a US institution (including minority-serving institutions, liberal arts colleges, and community colleges) supporting students such as women, minorities, first-generation scholars, and people with disabilities, who is interested in a virtual research experience alongside Berkeley Lab Computing Sciences (including NERSC) staff? If so, consider applying for the Sustainable Research Pathways Workshop (SRP) 2020. During the workshop, participating faculty will learn of funding opportunities to participate in Berkeley Lab's 2021 summer research program. For more information and to apply, please visit the [SRP Program Page]( Applications are due **this Friday, September 11.** ### IDEAS-ECP Webinar on Testing & Code Review Practices in Research Software Development on Wednesday <a name="ecpwebinar"/></a> The September webinar in the [Best Practices for HPC Software Developers]( series is entitled "Testing and Code Review Practices in Research Software Development" and will take place this Wednesday, September 9, 2020, at 10:00 am Pacific time. This webinar, presented by Nasir Eisty (California Polytechnic State University, San Luis Obispo), will cover the use of two software quality practices in the development of research software: software testing and peer code review. These practices can lead to not only improved scientific results through higher quality software in the short term, but also more maintainable software in the long term. Learn about the challenges, barriers, and necessary improvements to make the practices effective for research software development, based on studies of the research software community conducted via interviews, surveys, workshops, and tutorials. There is no cost to attend, but registration is required. Please register [here]( ([back to top](#top)) --- ## Updates at NERSC <a name="section3"/></a> ## ### Power Upgrade & Outage of NERSC Resources October 7-12 <a name="powerupgrade"/></a> To make the improvements required for Perlmutter, NERSC will take two machine room power outages this year. The first one was held July 10-13. **A second outage is now scheduled for October 7-12.** These two outages are necessary prerequisites for the installation of Perlmutter, the first components of which will begin to arrive later in October. More details will be provided in future communications. ### 2021 ERCAP Allocations Process Is Open! <a name="ercap"/></a> The ERCAP allocations process has now begun accepting requests for the 2021 Allocation Year (AY). Requests will be accepted through Monday, October 5, 2020. The majority of NERSC resources and compute time are allocated through the [ERCAP process]( Proposals are reviewed and awarded by Office of Science allocation managers and implemented by NERSC. For more information on the ERCAP process, please listen to [this podcast]( Please join us for virtual [office hours](#ercapofficehrs) next Thursday. ### Join Us for ERCAP Office Hours! <a name="ercapofficehrs"/></a> Allocations staff will once again hold virtual office hours via Zoom to assist users with finishing up and submitting their ERCAP requests, on the following dates: - Thursday, September 17 - Thursday, October 1 - Monday, October 5 (ERCAP due date) Office hours will take place from 9-11 am and 2-4 pm (Pacific time).
