NERSC remains in operation, with the majority of NERSC staff continuing to work remotely, and staff essential to operations onsite. We do not expect any disruptions to our operations in the next few months as the site reopens. 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 remains 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> ## ### (NEW) Jupyter Maintenance & Upgrade on Wednesday, 8-9 am (Pacific) <a name="jupyterupgrade"/></a> NERSC's Jupyter service will be upgraded Wednesday, May 18 between 8-9 AM PDT. Notebooks on Perlmutter will be shut down at 8 AM at the start of the maintenance, while notebooks on Cori will already be shut down for the Cori maintenance starting an hour earlier. When Jupyter returns to service, users will notice that JupyterLab has been upgraded to version 3.4, adding a number of new features summarized at this Jupyter [Discourse post](https://discourse.jupyter.org/t/jupyterlab-3-4-0-is-released/14106) and [change log](https://github.com/jupyterlab/jupyterlab/releases/tag/v3.4.0). We are also adding support for [Jupytext](https://jupytext.readthedocs.io/en/latest/) to provide two-way conversion between Jupyter notebooks and several other text-based formats like Markdown documents or scripts. ### (NEW) Join Us for the NUG Meeting, this Thursday 19 May, 11am PT <a name="nug"/></a> The NUG monthly meeting is a forum where NERSC and its users can celebrate successes, discuss difficulties and learn from each other. Our April meeting is **this Thursday, 19 May, at 11am** (Pacific time), at <https://lbnl.zoom.us/j/285479463>. This week our topic-of-the-day will be **The NERSC Annual User Survey**: Each year NERSC sends an annual survey to all users, and we use the feedback collected there to help identify what is working, and what improvements can have the most impact. This month, we'll take a look at some results from last year's survey. Our agenda for this month is: - **Win-of-the-month:** open discussion for attendees to tell of some success you've had -- e.g., getting a paper accepted, solving a problem, or acheiving something innovative or high impact using NERSC. - **Today-I-learned:** open discussion for attendees to point out something that surprised them, or that might be valuable to other users to know. - **Announcements and CFPs:** upcoming conferences, workshops, or other events that you think might interest or benefit the NERSC user community. - **Topic-of-the-day:** **The NERSC Annual User Survey**: we'll take a look at some of the outcomes of the 2021 Annual NERSC User Survey. - **Coming up:** Nominations and requests for future topics. We're especially interested to hear from our users - what are you using NERSC for, and what are you learning that might be helpful for other NERSC users, and for NERSC? - **Last month's numbers:** NERSC center metrics and info for the most recent month. Please see <https://www.nersc.gov/users/NUG/teleconferences/nug-meeting-may-19-2022/> for details. ### Allocation Reductions for Underusing Projects on Thursday <a name="allocred"/></a> Twice annually, NERSC performs allocation reductions on projects in the DOE Mission Science category (this includes the vast majority of projects). ALCC, Director's Reserve, Exploratory, and Educational projects are exempt from this process. The allocation reduction process takes unused allocation from projects not using them and allows DOE program managers to redistribute that time to other projects. In 2022, only CPU Node hours will be impacted. PIs and PI proxies may request exemptions, at least one week before the reduction date. The first allocation reductions will occur **this Thursday, May 19, 2022**. A second set of reductions will occur on September 15, 2022. For more information, including how much allocation will be removed, please see <https://www.nersc.gov/users/accounts/allocations/allocation-reductions>. ([back to top](#top)) --- ## Perlmutter <a name="section3"/></a> ## ### (UPDATE) Perlmutter Machine Status <a name="perlmutter"/></a> The initial phase of the Perlmutter supercomputer is in the NERSC machine room, running user jobs. Some nodes of the CPU-only second phase of the machine have been added to the machine. **NERSC will soon add all users to Perlmutter; expect additional communication with more details within the next few days.** This newsletter section will be updated each week with the latest Perlmutter status. ### Integration of Perlmutter Phase 2 Will Minimize System Downtime <a name="pmintegration"/></a> All cabinets for the second phase of Perlmutter have arrived or will arrive soon. The Phase 2 nodes need to be added to the system, and this integration process has been designed to minimize system downtime for users. You may see the number of nodes available continue to fluctuate, but we expect to be able to keep at least 500 Phase-1 nodes available to users throughout the process. While we will keep Perlmutter available as much as possible, it is not yet a production system so there are no uptime guarantees.
