The Bi cluster is operated for SMHI research and development. It follows in the footsteps of the earlier clusters Gimle, Dunder, and Krypton.

The Bi cluster has a LINPACK performance of approximately 326 Teraflop/sec using all 10,256 compute cores.

The system was delivered in the end of 2014 by ClusterVision and made available to users in March 2015.
