The Abel computer cluster

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.

Abel is a joint investment by the Research Council of Norway and UiO, and access is primarily through the Notur project. The cluster is available to all researchers.

Abel operational log

  • Disk problems on Abel Jan. 26, 2017 09:40 AM

    We are currently experiencing problems with two file servers on Abel. This leads to hangs for parts of /work. We are working with support to try and fix the problem.

    We are sorry for the inconvenience.

  • Failures on the /work file system Jan. 18, 2017 02:36 PM

    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.

  • Accidental reboot of login-0-2.local Dec. 7, 2016 11:02 AM
    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,

Further assistance or advice?

RCS Course Week

Apr. 4, 2017 09:00 AM - Apr. 6, 2017 04:00 PM

Training in using High-performance Computing (HPC) efficiently, for Abel and Colossus (TSD) users. The course is also open for all users of Notur systems, but examples and specifics will pertain to Abel and Colossus.

Apr. 6, 2017 09:00 AM - 04:00 PM

Short seminar to introduce the CodeRefinery project to the researchers and students at the University of Oslo. The goal of the project is to establish a software development e-infrastructure coupled with necessary technical expertise and extensive training activities in order to address the growing needs of computational communities.
