- | The cluster currently consists of eleven Transtec Calleo 642 servers, each containing four nodes with a mix of dual-CPU quad-Core CPUs and octa-Core CPUs, for a grand total of 512 cores. The nodes are interconnected by QDR Infiniband (40Gb/s) and are also connected to a dedicated ethernet switch with dual 1Gb/s ethernet links or a single 10Gb/s ethert link per node. The 23 Mark5s at JIVE are connected to the same networking at 1oGb/s in order to play back diskpacks for correlation. There is a 36-port Infiniband switch, another 24-port Infiniband switch, and a head-node for central administration and NFS exported homedirectories. | + | The cluster currently consists of eleven Transtec Calleo 642 servers, each containing four nodes with a mix of dual-CPU quad-Core CPUs and octa-Core CPUs, for a grand total of 512 cores.
