|---|---|
The vera1 login node has unknown likely hardware problems. Please prefer vera2 login node while we work on the problems. |
|
| The Icelake nodes in Vera has now been updated to Rocky Linux 9. | |
| The Zen4 expansion of Vera will go live. All Vera login nodes will be down during the day for the swap to the new login nodes under the same names. See Vera Zen4 news page for all details. | |
Due to high priority electrical work in the computer hall we need to cut power to the Vera Icelake nodes sometime in January. As it is not known when the necessary spare parts arrive, we have opted to not preemptively keep the Icelake nodes drained, but any running jobs will be interrupted when power is cut. Ensure that any long running jobs on -C ICELAKE checkpoint frequently. Skylake nodes should not be affected. |
|
| To better adhere to the Waymo license agreement we are changing the access mode. We will restrict access to the dataset starting in the second half of January this coming year. See our Waymo license instructions. | |
| We were experiencing some hardware issues since yesterday, which affected both clusters to a large degree. This issue appears to now be solved. | |
| Due to license restrictions centre provided conda containers and modules that uses default or anaconda channels will be replaced or removed. See our conda documentation. | |
44 new Vera ICELAKE nodes are now online in the main partition. Remember you have to request ICELAKE specifically to use these as the older SKYLAKE is still the default. |
|
The OpenOndemand portal for Vera cluster is now available at https://vera.c3se.chalmers.se. It provides a simple way to run interactive jobs on the cluster, such as jupyter notebooks, RStudio, VS code, and even a full desktop session. Anyone using srun for interactive jobs or the proxy server for running jupyter notebooks should switch to using this portal instead as it provides many advantages. |
