Berkeley Lab, where NERSC is located, is operating under public health restrictions. 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 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 and current known issues webpages.
The November webinar in the Best Practices for HPC Software Developers series is entitled "55+ Years in High-Performance Computing: One Woman's Experiences and Perspectives" and will take place this Wednesday, November 10, 2021, at 10:00 am Pacific time.
This webinar's format will be different than the others. 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 have 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.
The initial phase of the Perlmutter supercomputer is in the NERSC machine room, booting and running successfully.
We have added many early users onto the machine. We hope to add even more users soon.
The second phase of the machine, consisting of CPU-only nodes, will arrive in early 2022. After all the new nodes arrive, all of Perlmutter will be taken out of service and integrated over a period that we anticipate could take up to 8 weeks.
This newsletter item will be updated each week with the latest Perlmutter status.
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 with any questions or issues.
Python users take note: On Jan 19, 2022 at the Allocation Year rollover, NERSC will change our default Python and Python3 modules on Cori to python/3.8-anaconda-2021.05. Please note that older Python modules will remain available, but users must specify the full module name to continue to use them.
Updates in this module include:
- Mamba 0.7.3 (a faster alternative to conda)
- netcdf4 1.5.3
- mpi4py 3.1.1
- authlib 0.15.4 (support for NERSC's Superfacility API)
Full release notes are available here: https://docs.anaconda.com/anaconda/reference/release-notes/#anaconda-2021-05-may-13-2021.
pip users should be aware that pip packages installed via --user will be
installed at $HOME/.local/cori/3.8-anaconda-2021.05 (defined by
$PYTHONUSERBASE).
This module is available now via module load python/3.8-anaconda-2021.05, so
we encourage you to test it now. If you notice issues or have questions please
contact us at https://help.nersc.gov. NERSC Python users will find a lot of
helpful information and advice in our Python documentation: https://docs.nersc.gov/development/languages/python/nersc-python/.
Note that the python/3.8-anaconda-2021.05 module is already the default on Perlmutter. There are no scheduled Python module changes on Perlmutter.
The NERSC 2020 Annual Report (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.
