23/04/2024 - Hydra system upgrade with brand new nodes
We are very pleased to announce the ready availability of 20 new nodes in Hydra with last-generation CPUs and a larger memory and cache per core than usual. Alongside the addition of these new nodes, we are also upgrading the operating system of rest of the cluster, which will require a planned reboot of the login nodes on Friday 26/4 at 06:00 (CEST) rendering the cluster inaccessible for a maximum of 15 minutes. Queued and running jobs will not be disrupted.
Quick Reference Documentation#
The quick reference documentation offers structured and concise information for the day-to-day use of the HPC services in VUB. It focuses on our tier-2 cluster Hydra and covers all levels of expertise, from the VSC account creation to software optimization tips. Our documentation centre is also a point of entry to the extensive documentation available in the VSC documentation website.

As announced on WeAreVUB Staff, on Saturday April 6th, the VUB network team will perform network updates on the VUB campus, which will impact any internet connection between VUB and the outside world.
18/03 - Softening environment of Julia modules
We improved how we handle installations of Julia and Julia packages in Hydra. From now on, software modules in the cluster providing a base installation of Julia or any Julia package will not lock the working environment in any way upon load. This translates to the following features:
09/02 - Your OneDrive in VUB can now be used from Globus
We are happy to announce that it is now possible to connect your OneDrive storage (including SharePoint) in your VUB account to the Globus network. This provides a convenient method to move your data between OneDrive and the storage on all VSC clusters, as well as to any other computer you are currently using in Globus.
09/01 - Hydra scratch flash storage upgrade part 2 on 10 January 2024
On 10 January 2024 between 9:00-15:00, we will finalize the flash storage extension of Hydra’s scratch filesystem. During the upgrade, we will stop the scheduler to avoid putting load on the storage, and the performance of the scratch will be decreased. Running jobs will continue to run, and jobs in queue will remain queued.

Hydra user survey#
Once a year we carry out a user survey to gather feedback about their experience in our HPC clusters. The questions cover the full cycle of cluster usage, from getting access to the specific infrastructure needs of experienced users. The goal is to identify the weak and strong points in our scientific computing services as guidance for improvement in the future.
Results of the User survey 2022 show a very good satisfaction level of our users with the services provided by the VUB-HPC team and some interesting trends for the future.
All published surveys can be found in the survey list.
