.. _news: News & Events ============= * General information about the :ref:`maintenance` is applicable to all scheduled downtime periods. * Any additional information is outlined in notification emails to hpc-users@uci.edu (all current users) and is described in the details below. * When the maintenance is completed all users are notified via emails to hpc-users@uci.edu. July, 2025 ------------- | :blogtitle:`HPC3 Downtime July XX, 2025` | :blogauthor:`2025-05-13 by Nadya Williams` | The next outage will be July (date to be determined), 2025, beginning at 8am. | The cluster will be unavailable all day. Maintenance Items: 1. OS version update from **Rocky 8.10 to Rocky 9**. #. Top-to-bottom re-installation of all compute and login nodes. #. Full rebuild of all applications software, see table below for software changes. #. Full rebuild of Slurm software. Impacts: This is a full outage. #. All existing logins will be terminated. #. You will NOT have access to HPC3 during the planned downtime. #. You will have access to CRSP using `Web based File browser` or `CRSP Desktop App`. #. No Slurm jobs can run or can be pending in the queue. #. :red:`All jobs remaining in the queue on the maintenance day will be terminated`. #. Slurm jobs that are not guaranteed (via TimeLimit) to complete before 8am on the day of maintenance will need to be resubmitted after the maintenance. Please see :ref:`requesting time limits ` on queues. Software changes: The operating system update involves many changes across the software stack. While we try to build all the previous software versions for the new OS, some builds are impossible. As a result, some modules will be removed because they cannot be built on a new system or because the underlying requirements are no longer satisfied. *Note, the table below will be periodically updated till the maintenance date*. .. table:: **Software changes** :align: center :class: noscroll-table :widths: 50,50 +--------------------------------------------------------+------------------------------------------------------+ | Module name | Comments | +========================================================+======================================================+ | .. centered:: :blue:`Removed modules` | +--------------------------------------------------------+------------------------------------------------------+ | bcftools/1.10.2 | Cannot build, use newer version | +--------------------------------------------------------+------------------------------------------------------+ | bustools/0.40.0 | Unused, use newer version | +--------------------------------------------------------+------------------------------------------------------+ | canu/2.0 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | charm/6.10.1/gcc.11.2.0 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | charm/6.10.1/gcc.11.2.0-openmpi.5.0.1 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | charm/7.0.0/gcc.11.2.0 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | cuda/10.1.243 | Not supported on Rocky 9, use newer version | +--------------------------------------------------------+------------------------------------------------------+ | gatk/4.1.9.0 | Security vulnerability, use newer version | +--------------------------------------------------------+------------------------------------------------------+ | gromacs/2021.2/gcc.8.4.0-cuda.10.1.243.openmpi.4.0.3 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | gromacs/2022.1/gcc.8.4.0-openmpi.4.1.2 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | intel/2020u1 | Intel compiler deoends upon a shared library that | | | is unavailable on Rocky 9. | | | | | | Removed affected modules: | | | | | | * mpich/3.4/intel.2020u1 | | | * openmpi/4.0.3/intel.2020u1 | | | * hdf5/1.10.5/intel.2020u1 | | | * ioapi/3.2/intel.2020u1 | | | * netcdf-c/4.7.0/intel.2020u1 (including | | | dependent netcdf-f version 4.5.2) | | | | | | Use modules with newer intel compier where available | +--------------------------------------------------------+------------------------------------------------------+ | ioapi/3.2/gcc.11.2.0 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | petsc/3.20.1/gcc.11.2.0 | Unused | | | | | petsc/3.20.1/gcc.11.2.0-cuda.11.7.1 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | protobuf/3.11.4 | Unused | | | | | protobuf/3.19.4 | Unused | +--------------------------------------------------------+------------------------------------------------------+ | R/4.1.2 | Seurat and leiden libraries cannot be | | | built.
