The job scheduler in Hydra will be put on pause on Thursday, 16th September from 20:00 to 22:00. We will perform minor updates to the MPI stack in
intel toolchains. Running jobs will not be affected and users will be able to continue submitting jobs to the queue during the pause.
Login nodes updated successfully. The system update for the rest of the nodes continues as planned.
The last stable version of TensorFlow is now installed in Hydra. You can load TensorFlow v2.5.0 with the following modules:
The recent major release of ORCA version 5.0.0 is now installed in Hydra. You can load it with the module
Warning On Tuesday June 15 at 20:00 the login nodes will be unavailable for 30 minutes.
We have published the results of our yearly user survey, conducted in February 2021. Feedback from users’ experiences in Hydra adds valuable insight into their needs, what works well, and what needs further improvement.
We have improved the recommended usage of the OneDrive client in Hydra. Check the FAQ in the link below.
The maintenance on the storage is done and jobs are again running as normal. We are still busy with (automatically) updating all worker nodes. Until that is done, the queuing time will be slightly longer than normal.
Due to maintenance work, it will not be possible to submit new jobs or view the status of submitted jobs on Saturday 29/8 between 20:00 and 23:00. Running jobs will not be impacted.
Warning Until next Friday (14th of August) IvyBridge nodes will be offline due to the current heatwave. All other nodes are online, including GPU nodes. Since the scope of this mesure is rather limited, the waiting time of jobs in the queue should not be affected.
From 2 to 3 June 2020, works on an electric board of the SISC cooling system will be conducted. The operations will require to stop the cooling system for short periods of time. The computing power of the HPC clusters Hydra and Vega will be reduced to a minimal level to avoid heat problems in the data center. Therefore, waiting time for jobs in the queue will be higher then normal.
Due to the recent wave of cyberattacks on HPC centers throughout Europe, the SISC HPC team will take security hardening measures on Hydra, in consultation with the VSC.
There are a couple of hardware issues with the Hydra storage which we cannot safely fix while the cluster is running. We are going to shut down Hydra on Monday 18 May, starting at 09:00 to perform the needed repairs. We expect that we can resume normal operations by the late afternoon.
The network issues are fixed. Everything is back to normal.
login1 server has to be rebooted to apply critical updates. This will be done on Saturday at 20:00. You can use
login2.hpc.vub.be as an alternative login server during the downtime.
