C3SE is also part of Swedish Science Cloud and Swestore


Date Text
2024-02-22 Vera system upgrades: Firmware updates, RockyLinux 8.9, Mellanox 5.8. /mimer is now mounted on Vera. /apps is mounted to a new filesystem. The module tree will change slightly. The same firmware, OS, driver upgrades will also be applied on Alvis soon.
2024-02-16 Network problem reoccurred. Problem has now been isolated to a single faulty piece of network equipment which have managed to cause massive packet loss throughout the networks. Clusters have once again been restored to functional order.
2023-11-29 Network problems brought down part of the central storage. Some jobs may have been lost and there was likely many problems logging in.
2023-09-27 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.
Chalmers e-Commons is still hiring.; system administrators and systems engineer.
