Hardware, Embedded Systems The University of Cambridge have joined forces with Dell to unveil one of the world's fastest supercomputers. The machine, called Darwin, consists of 2340 computers arranged in a cluster. It has been ranked as Europe's seventh fastest supercomputer, and the 20th fastest in the world, according to the top 500 list.

yes, it runs linux.

the thing has more than 27 TeraFLOPs (27 x 1012 calculations per second) of raw computing power.

576 Dell PowerEdge 1950 compute servers in the cluster have two Dual-Core Intel Xeon 5160 processors at 3GHz and 8GB of memory.

all compute servers are interconnected by an InfiniBand network from QLogic InfiniPath host adapters and switches from SilverStorm Technologies. 60 TeraBytes of storage is provided by 18 Dell PowerVault MD1000 disk arrays connected to the cluster network over 10 Gigabit Ethernet links. the storage pool is managed by the TerraGrid parallel filesystem.

the cluster runs the ClusterVisionOS, ClusterVision's own Linux-based cluster software distribution which provides an integrated software environment for the effective use and management of the system.

the cluster comprises nine computational units (CUs), each with its own ClusterVisionOS Sub-Master. Each CU has 65 nodes for computation. the CUs are managed by two failover Sub-Masters. the CUs can run independently - if one CU fails the other CUs will keep on functioning. also, if one of the ClusterVisionOS Main Masters fails, the cluster will keep on running. user jobs, however, are not limited to a single CU and can span multiple CUs. The construction using independent CUs allows for scaling up to far larger clusters with tens of thousands servers. users log into one of the four DNS balanced ClusterVisionOS Login Nodes.

hope it helps.
