Known issues

Some functionality, software, useful tools, and other things are still be missing. The things that we are aware of are listed on this page, and we will update the page whenever the status changes or when new issues have been identified. For other kind of issues, please also check the HPC status page.

All directories from Peregrine's /home and /data file systems are being copied to /mnt/pg-home and /mnt/pg-data. This is still ongoing, and we will keep synchronizing these files until Peregrine is shut down. This means that if you still make any changes to your files on Peregrine, they will show up on Habrok as well (with some delay). On Thursday, March 30, we will disable access to Peregrine, and do one final synchronization of the data to Hábrók, which will likely take about a day.

Update March 31, 17:00: the migration of the home directories has completed, which means that you should be able to find all your files in /mnt/pg-home/$USER. The migration of /data is still ongoing.

Update April 1, 21:00: the final sync of Peregrine’s /data to Hábrók (/mnt/pg-data) has completed as well, which means that all files should now be available.

Though we have started making Hábrók accounts, we still need to create all (relevant) groups that were available on Peregrine, and add accounts to the right groups. This means that you may not be able to access any group directories or group software yet, but we will do this in the week of March 27-31. Do note that, even though you may not be able to access it yet, all group data will be migrated from Peregrine to Hábrók and will not be removed.

Update 2023-04-05: Most of the original pg-groups have been recreated on Habrok with the prefix hb-. In case your group is not there, please let us know.

We've already installed quite a few (popular) software modules, but not quite as many as were available on Peregrine. We're still installing some new applications (based on the ones that were recently used on Peregrine), usually only the latest available versions. If there is anything in particular that you would like to have installed on short notice, please let us know.

Update April 13: a first release of jobinfo is now available. It's still lacking GPU usage information for GPU jobs.
Update April 18: the hbquota tool for showing information about your quotas on different file systems is now available.

The web portal (https://portal.hpc.rug.nl) has not been migrated to Hábrók yet. We are currently working on that, and will update this issue as soon as the portal is available.

The Peregrine GPU nodes equipped with an Nvidia V100 GPU will be migrated to Hábrók. As they are running in a different infrastructure and different data center, they are not available yet.

The GELIFES nodes have not been migrated to the Hábrók environment yet. Meanwhile, there is some interim capacity, so the gelifes partition can already be used on Hábrók by GELIFES users.

At the moment, F-accounts cannot use MFA, and thus cannot log into Hábrók. We are working on a temporary workaround that would enable F-accounts to login to Habrok, and hope to have something available until the end of April. Please keep an eye on this page for further information.

Update: unfortunately, setting up MFA for F-accounts turns out to be impossible. Instead, external collaborators should get an OEP (externall staff) identity via the HR department.

The Slurm scheduler has not been connected to a mail server yet and getting mail notifications is not possible. We are working on this issue, so please keep an eye on this page for updates.

Interactive jobs, submitted as described on Interactive jobs, may not be using the software stack that was built for the CPU type of the allocated job, which could lead to application warnings or errors. In order to work around this, you can run module update when the interactive job has started.
