This is a Cray supercomputer built probably in 2004. It came from the MOD as surplus in Jan 2010. It came with no disks, but complete with the Sun Sparc 5 front console machine. Note that its missing the left hand rack (see below).

Cray SV1

 

It has two procesor cards, each with 4 processors and 8 memory cards (possibly 256Gb). Each processor has a peak rate of 1.2 to 4.8Gflops thus the machine is 9.6Gflops to 38.4Gflops, the highst in the collection as of jan 2010.

 

Here are some specifications of the machine (its a Cray SV1-1) from here.
