Merrimac uses stream architecture and advanced interconnectionnetworks to give an order of magnitude more performance per unit costthan cluster-based scientific computers built from the sametechnology. Organizing the computation into streams and exploitingthe resulting locality using a register hierarchy enables a streamarchitecture to reduce the memory bandwidth required by representativeapplications by an order of magnitude or more. Hence a processingnode with a fixed bandwidth (expensive) can support an order ofmagnitude more arithmetic units (inexpensive). This in turn allows agiven level of performance to be achieved with fewer nodes (a 1-PFLOPSmachine, for example, with just 8,192 nodes) resulting in greaterreliability, and simpler system management. Merrimac is designed to be a streaming scientific computer that can be scaled from a $20K 2 TFLOPS workstation to a $20M 2 PFLOPS supercomputer.
Recent News- Streaming Supercomputer officially namedMerrimac, which is a Native American word meaning "swift stream".
