CoE HPC News, July 12 2022 Edition: HPC Portal Maintenance, Jupyter Lab and more
by Yelle, Robert Brian 12 Jul '22

12 Jul '22

HPCC users, Please check out the latest HPC cluster news below. HPC Portal maintenance The HPC Portal will be offline next Monday morning the 19th for maintenance. During this time, the Web and Portal packages will be updated, and to replace expiring SSL certificates. Jobs running through the portal at the time should not be interrupted, but they will not be accessible until the portal is back online. The portal is expected to be back online by noon on the 19th. New Jupyter Server app An improved Jupyter Server app has been added to the list of Interative Apps on the HPC Portal. This app gives you the option to use Jupyter Lab, and allows you to specify your own Python or Conda environment to run Jupyter, if desired. This app is in beta testing phase and will eventually replace the existing Jupyter Notebook app. Preempt Partition The “preempt” partition has undergone a lengthy testing period, and is being used with increasing frequency and bears mentioning. The preempt partition is available to all users, but it is not the same as the share partition. It is a low priority partition which can give you access to unused resources, but that access can be cancelled or “preempted” by a higher priority request or job. The preempt partition can be useful for those who have jobs that are restartable or checkpointed, or for short jobs or requests, i.e. where there is low risk or mitigated loss to interruption. It is not recommended to use this partition for long jobs that are not checkpointed. New Software installs Here is a list of recent software installs: GCC 12.1, 11.3, 9.5 Mathematica 13.0 Matlab 2021b-r3 with Parallel Server. If anybody is interested in using Matlab Parallel Server, please contact me. Anaconda 2022.05, will become the new default version Cuda 11.7 have been installed, and Nvidia drivers have recently been upgraded on most GPU nodes to support the latest Cuda version. Drivers for Cuda 11.5+ have not yet been released for the DGX systems. The software listed above can be accessed through the modules system, type “module avail” to see what is available.
