The cluster contains 672 nodes each in a dual quad-core configuration, for a total of 5376 cores. The CPU:s are the Intel L5420 low-power CPU:s running at 2.5 GHz, giving each node a total peak performance of 80 Gflops/s. Each node is equipped with 16 GB RAM for a total of more than 10 Terabytes of RAM. For high parallel performance, the system is equipped with a high bandwidth, low latency InfiniBand interconnect. Scratch storage is provided by a 100 TB disk-subsystem running GPFS. For more information about the system and available software see the HPC2N web-pages.
Akka will be closed down at the end of 2012. In this round we will only award 6 months allocations.

Triolith (triolith.nsc.liu.se) was a capability cluster with a total of 24320 cores and a peak performance of 428 Tflops/s. However, Triolith was shrunk by 576 nodes on April 3rd, 2017 as a result of a delay in funding a replacement system and now has a peak performance of 260 Teraflop/sec and 16,368 compute cores. It is equipped with a fast interconnect for high performance for parallel applications. The operating system is CentOS 6.x x86_64. Each of the 1520 (now 944) HP SL230s compute servers is equipped with two Intel E5-2660 (2.2 GHz Sandybridge) processors with 8 cores each (i.e. 16 cores per compute server). 56 of the compute servers have 128 GiB memory each and the remaining 888 have 32 GiB each. The fast interconnect is Infiniband from Mellanox (FDR IB, 56 Gb/s) in a 2:1 blocking configuration.
Triolith have been replaced with a new system, Tetralith, that was made available to users on August 23, 2018. NSC currently plan to keep Triolith in operation and available to users until September 21st, 2018. After that, Triolith will be permanently shut down and decommissioned.
