Named after the famous Norwegian mathematician Niels Henrik Abel (1802 – 1829), the Linux cluster at UiO is a shared resource for research computing capable of 258 TFLOP/s theoretical peak performance. At the time of installation Abel reached position 96 on the Top500 list of the most powerfull systems in the world.
Abel is an allround, allpurpose cluster designed to handle multiple concurrent jobs / users with varying requirements. Instead of massively parallell applications, the primary application profile is for moderately to smaller parallel applications with high IO and/or memory demand. Frequent users of Abel are from the life sciences, astrophysics, geophysics, chemistry and also humanities. All compute nodes on the cluster have a minimum 64 GB RAM, 16 physical CPU cores and are connected by FDR (56 Gbps) Infiniband.
Failures on the /work file system

Dear Abel users,
The last two days we have experienced a series of short crashes of the /work file system. This leads to many jobs hanging, and we will unfortunately have to requeue many of them. We are in contact with the file system vendor in order to understand and prevent these failures.
We are sorry for the problems this creates.

Dear Abel user,There was and Accidental reboot of login-0-2.local, if you had logged in to Abel using this node you may have experienced this. There is no effect on running jobs due to this.Sorry for the inconvenience,
Short stop of queue system at 09:00

There will be a short stop of the queue system at 09:00 today, due to maintenance. Running jobs will not be affected, but commands like squeue and sbatch will not work during the stop.
