All times are **Pacific Time zone** ### Other Significant Dates ### - **February 3, 2020**: ALCC Applications close ## Recap: Northern California power outage October 26 <a name="poweroutage"/></a> ## The California wildfire season continues and only two weeks after the conclusion of the first PG&E Public Safety Power Shutdown (PSPS), a second PSPS affecting NERSC was announced on Friday October 25. On Saturday morning the expected start was moved forward, and in response NERSC began shutdown procedures around 1:30pm. At about 2pm on Saturday October 26, Cori and the NERSC filesystems became unavailable to users. Our generator is able to supply power for web services, databases and other auxiliary services, and fortunately we were able to keep these running for the duration of the PSPS. On Monday evening PG&E announced that power to Berkeley Lab's substation was restored, and work began to return power to the Lab, including NERSC. NERSC power was restored late on Monday night, and early on Tuesday work began to restore NERSC systems to service. NERSC was back to full service a little before 7pm PDT on Tuesday October 29. Some scheduled maintenance and some user-training events were delayed or modified as a consequence of the outage, we apologize for the inconvenience to our users. We would like to thank our users for your patience and support again during this second outage. We hope that this will be the last such outage, but should another PSPS occur we plan to keep our users well-informed of events. <> will also continue to indicate the status of Berkeley Lab. ## User training on checkpointing and restarting jobs using DMTCP, Wednesday November 6 <a name="dmtcp"/></a> ## The one-hour user training on checkpoint/restart using DMTCP has been moved to **this Wednesday, November 6** from 10:00-11:00 am PT. DMTCP is a transparent checkpoint/restart tool, requiring NO modifications to user codes. The goal of this training is to help users get started with DMTCP. The benefit of using DMTCP includes an improved job throughput, a [75% charging discount]( via the [flex]( QoS, and a capability of running jobs with any length on Cori. Registration information and agenda for the day are available at: (note that the URL still includes the original date, but the actual training date is Nov 6) ## October NERSC Science Highlights <a name="highlights"/></a> ## NERSC collects highlights of recent scientific work carried out by its users, and these may be featured on NERSC and DOE web pages, in press releases, and in other communications that emphasize the value of High Performance Computing in science. Our [most recent presentation of Science Highlights](, released on October 15, is comprised entirely of science highlights submitted by our users via the form at <>. We'd love to hear about your work and acheivements using NERSC systems. If you have work that you'd like us to highlight, please send us the details via [the form above]( ## New Requirement for ALCC Proposals <a name="alcc"/></a> ## For the 2020-2021 ALCC campaign, PIs are **required** to submit a Letter of Intent (LOI) as the first step of submitting a proposal. The ALCC submission site (<>) opened October 1, with LOIs due on December 16. All proposals are due when the submission site closes at 11:59 PM (Eastern Time) on February 3, 2020. Information from the LOI will be automatically populated to the proposal by December 18. Details about submission requirements can be found at <>. ## PASC20 Call for Submissions <a name="pasc"/></a> ## The Platform for Advanced Scientific Computing (PASC) invites research paper submissions for PASC20, co-sponsored by the Association for Computing Machinery (ACM) and SIGHPC, which will be held at the University of Geneva, Switzerland, from June 29 to July 1, 2020. PASC20 is the seventh edition of the PASC Conference series, an international platform for the exchange of competences in scientific computing and computational science, with a strong focus on methods, tools, algorithms, application challenges, and novel techniques and usage of high performance computing. The technical program is centered around eight scientific domains, including chemistry/materials, climate/weather, computer science/applied math, life sciences, physics, solid earth dynamics, engineering, and emerging application domains. The final deadline for submissions is **December 15, 2019**. For more information on PASC20, including submissions, please see <>. ## NERSC Will Support Only Python3 in New Allocation Year <a name="python2"/></a> ## Python 2 will reach its end of life on [January 1, 2020](, at which point there will be no more development, bug fixes, patches, etc. Therefore, upon the beginning of the 2020 Allocation Year at NERSC, the following changes to Python support will occur at NERSC: - At the AY rollover, the default Python module will become a module based on a Python 3 distribution. - The old Python 2 module will remain available for use but users must specify the version suffix. - No new installations of Python 2 packages or modules will be performed. - During the next Cori operating system upgrade, which could occur sometime in 2020, the Python 2 module will be retired. NERSC will actively support only Python 3 (or future Python versions should Python 3 become deprecated) on Perlmutter and future systems. Please let us know your questions via a ticket to <>. ## This Week on "NERSC User News" Podcast: Alvarez and Hopper Postdoctoral Fellowships <a name="podcast"/></a> ## In this week's NERSC User News podcast, NERSC Application Performance Specialist Brian Friesen talks about the Luis W. Alvarez and Grace M. Hopper Postdoctoral Fellowships: what they are, how to apply, and how the Hopper fellowship compares with the NERSC NESAP postdoctoral positions. The NERSC User News podcast, produced by the NERSC User Engagement Group, is available at <> and syndicated through iTunes, Google Play, Spotify, and more. A direct link to this week's podcast is <>. Please give it a listen, and let us know what you think via a ticket at <>. ## Come Work for NERSC! <a name="careers"/></a> ## NERSC currently has several openings for postdocs, system administrators, and more!
