Cluster Matilda

The cluster will be down as we apply updates and upgrade cluster management software, apply OS updates, and firmware upgrades.

We expect significant downtime for the cluster as we perform this maintenance.

As a reminder, we also have HPC resources at MSU iCER which may be of use during this downtime. See MSU_iCER_HPCC_Research_Cluster for details on requesting access if you don't have it already.

Cluster Matilda

We will be draining nodes and applying Dell firmware updates. This should not be disruptive to jobs but will reduce some of the capacity of the cluster as we take idle nodes out of service to apply updates.

We will be upgrading to a subscription-based version of Globus that will permit users to share Guest Collections with collaborators outside of OU.

Please refer to the Globus Archives documentation for more information.

We will be evaluating OpenMPI performance and optimization and making any necessary changes.

OpenMPI version 4.1.1c was tested and installed - module load OpenMPI/4.1.1c

Please refer to the MPI Job Script documentation for important changes when compiling or running OpenMPI capable applications.

Matlab Version R2022b was installed - module load MATLAB/R2022b

For the latest information, please refer to the MATLAB HPC reference. Please update your off-cluster scripts if you'd like to run the new version of MATLAB remotely.

SLURM Upgrade - We upgraded to version 21.08

SLURM Configuration - New queues were added for short (<=4 hrs) and long jobs, as well as buyin users. For a complete list of all changes, see the Feature Updates

OS Upgrade - RHEL 8.6

Firmware and BIOS updates

Driver Updates - Infiniband networking, Lustre (/scratch) and NVIDIA GPUs

Date: May 07, 2022

Cluster Matilda

NVIDIA/Mellanox Switch failed making Infiniband Network, MPI jobs, and /scratch storage inaccessible. We are working with Dell and NVIDIA to get a replacement ASAP.

May 12, 2022 - We moved around the remaining functioning switches and restored the Infiniband network to about two thirds of the cluster. Still waiting on a replacement switch.

May 17, 2022 - Replacement switch has been installed and configured. All compute nodes are back online with /scratch available.

Cluster Matilda

The primary storage system (Dell EMC Isilon) for home directories, project space, and software will be upgraded. The upgrade is a rolling upgrade of the storage system cluster nodes so should not be disruptive, however, there is a possibility that jobs and the cluster will be unavailable.

Date: April 28 - April 30, 2021

Cluster Matilda

Files on scratch space are currently not purging as expected for files not accessed in 45 days. We will purge files and implement a script to perform this purge on an ongoing basis.

Cluster: Matilda

The system will be reconfigured to utilize the TMod module system instead of the LMod module system. LMod is backwards compatible with TMod so users should not experience any issues with existing job submission scripts.
