Intel16 Cluster Currently Offline - RESOLVED 11/19/2024
RESOLVED: 11/19/2024 12:10PM - On 11/18/2024 ITS performed maintenance on a number of switches in the data center that required rebooting critical network infrastructure. After these reboots, several links connecting to the intel16 cluster did not recover. During this time, you may have also noticed brief pauses in OnDemand and on Gateway nodes. This morning we were able to work with ITS to re-establish connectivity to all intel16 nodes, and the intel16 cluster, along with all other nodes, are now back in production and running jobs via Slurm.

OpenMPI/4.1.5-GCC-12.3.0. This will result in errors from the module system when logging in, as the module needs to be deleted to be rebuilt. This will not affect running jobs, and will be isolated to development nodes only. The rebuild should be complete by 6:00PM at which time this blog post will be updated. -
Update details about current filesystem and OnDemand issues
OnDemand: OnDemand is periodically losing connection to our gateway nodes. This makes home and scratch unavailable. We are still investigating the cause. Home directories: The home file system underwent diagnostics from 6/24-6/28. This caused slowdowns for logging in and using the HPCC. We have restarted our backup process after the scan ended 6/28 evening and users may see pauses as the file system catches up. NewOS: We upgraded our operating system to Ubuntu 22.04 in mid June. This included a reinstallation of all software modules. Please read our documentation here for more details about the upgrade, and contact us if you are having issues not covered by this documentation. Please click the title of this post for more detailed information and our planned timeline. Updated: 7/10 at the end.
-
Current system issues
We are aware of two issues affected the system at this time: slow response to commands/slow login, and OnDemand scratch space missing. The system slowdowns are caused by diagnostics on the home filesystem as part of our upgrade to a new home filesystem. We do not currently have an estimate for when these diagnostics will complete. The OnDemand scratch space connection is also being diagnosed and addressed with our storage vendor. Please check back for updates as we have them.
-
Home filesystem issues affecting OnDemand
OnDemand functionality has been partially recovered. Users should be able to log in, connect, and access their home and research spaces, as well as interactive app sessions. Scratch remains unavailable at this time. Please report access issues at https://contact.icer.msu.edu/contact

VSCode updates will break access
This post applies to users of VS Code that SSH into the ICER HPCC from their own copy of VS Code.
Error message: “This machine does not meet Visual Studio Code Server’s prerequisites, expected either…: - find GLIBC >= v2.28.0 (but found v2.17.0 instead) for GNU environments”
Details Microsoft recently updated Visual Studio Code to version 1.86, and it is no longer compatible with the operating system we use at ICER. The change note that lists the change is here https://code.visualstudio.com/updates/v1_86#_engineering (scroll down to “Linux minimum requirements update”) Although we plan to upgrade our operating system this year, in the meantime there are two solutions to this incompatibility.
Solutions
1) Use our code server app in OnDemand (Interactive Apps -> Code Server (beta)) You can request compute nodes to work on for a specified amount of time, and use VS Code in your browser.
2) Downgrade to the previous 1.85 version of VS Code and disable automatic updates. You can access the previous version here https://code.visualstudio.com/updates/v1_85 (see the Downloads section for a version for your PC or Mac)
