COSMA 6 has about 600 compute nodes, each with 128GB RAM and 16 cores (2x Intel Xeon CPU E5-2670 0 @ 2.60GHz). COSMA6 therefore includes about 10,000 compute cores, based on the Sandy Bridge architecture.
The nodes are connected via Mellanox FDR10 Infiniband switches in a 2:1 blocking configuration. Access is enabled through a login/development server with 512GB of memory. Currently connected is Lustre storage system configured with 2.6 PB of data space.
