+- `$HOME`: Mounted via NFS across all nodes. It is slow and has low capacity.

+- `/ceph/home/$USER`: Shared Ceph file system across jungle nodes. Slow but high

 - `/nvme{0,1}/$USER`: The two local NVME disks, very fast and large capacity.
 - `/tmp`: tmpfs, fast but not backed by a disk. Will be erased on reboot.

-title: "Update 2025-09-26"
-author: "Rodrigo Arias Mallo"
-date: 2025-09-26
----
-
-This is a summary of notable changes introduced in the last two years. We
-continue to maintain all machines updated to the last NixOS release (currently
-NixOS 25.05).
-
-### New compute node: fox
-
-We have a new [fox machine](/fox), with two AMD Genoa 9684X CPUs and two NVIDIA
-RTX4000 GPUs. During the last months we have been doing some tests and it seems
-that most of the components work well. We have configured CUDA to use the NVIDIA
-GPUs, as well as AMD uProf to trace performance and energy counters from the
-CPUs.
-
-### Upgraded login node: apex
-
-We have upgraded the operating system on the login node to NixOS, which now runs
-Linux 6.15.6. During the upgrade, we have detected a problem with the storage
-disks. The `/` and `/home` partitions sit on a
-[RAID 5](https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_5),
-transparently handled by a RAID hardware controller which starts its own
-firmware before passing the control to the BIOS to continue the boot sequence. A
-problem during the startup of the firmware prevented the node to even reach the
-BIOS screen.
-
-After a long debugging session, we detected that the flash memory that stores
-the firmware of the hardware controller was likely to be the issue, since
-[memory cells](https://en.wikipedia.org/wiki/Flash_memory#Principles_of_operation)
-may lose charge over time and can end up corrupting the content. We flashed
-the latest firmware so the memory cells are charged again with the new bits and
-that fixed the problem. Hopefully we will be able to use it for some more years.
-
-The SLURM server has been moved to apex which allows users to also submit jobs
-to fox.
-
-### Migrated machines to BSC building
-
-The server room had a temperature issue that had been affecting our machines
-since the end of February of 2025. As the summer approached, the temperature
-exceeded the safe limits for our hardware, so we had to shutdown the cluster.
-
-![Room temperature](temp.png)
-
-Since then, we have moved the cluster to BSC premises, where it now rests at a
-stable temperature, so hopefully we won't have more unscheduled downtime.
