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

  • Network problems May 11, 2016 11:28 AM

    Due to a switch failure, Abel is inaccessible at the moment. We are working on the issue, but at this point it is not certain when we will be back online.

    Update: Fautly switch has been fixed and Abel is now in production.

    Due to the network outage a number of jobs failed to start. Those jobs need to be resubmitted manually. We encourage all users to check the status of their runs.

  • Abel is back Apr 29, 2016 09:25 PM

    The issue with file system is now solved, and Abel should function as normal. Please let us know if you experience any thing out of ordinary.. Thank you to everyone sacrificed the Friday evening to solve this issue.

  • Abel login issue Apr 29, 2016 06:16 PM

    Some users are experiencing login issues at the moment. We are working on finding the cause. .
