COSMA 6 has now reached end of life and was retired in April 2023, after 11 years of operation (first at Daresbury, then as part of COSMA). It had about 600 compute nodes, each with 128GB RAM and 16 cores (2x Intel Xeon CPU E5-2670 0 @ 2.60GHz). COSMA6 therefore included about 10,000 compute cores, based on the Sandy Bridge architecture.

The nodes were connected via Mellanox FDR10 Infiniband switches in a 2:1 blocking configuration. Access was enabled through a login/development server with 512GB of memory. A Lustre storage system configured with 2.6 PB of data space was available.
