The SX (SNOLab) Cluster
Among other spezialized smaller clusters, we operate a "Gridrack" consisting of 37 Dell PowerEdge R410 Servers that have 2 sockets with a 6-core Intel Xeon processor (Intel x5670 / x5675) that runs at 2.9/3.07 GHz. These nodes offer a total of 12 cores that are 2-fold hyperthreaded, i.e. they support up to 24 threads. The scheduler is configured such that only 12 threads are run at a time. These nodes have 64 Gbyte or 32 Gbyte of physical memory.
All nodes have 32/64 Gigabytes of RAM available and are connected by a Gigabit Ethernet interconnect
