A HyperTransport-based personal parallel computer

Instead of all using commodity components, an approach building a personal parallel computer on top of a non-coherent HyperTransport (HT) fabric is presented in the paper. The advantage is to provide both lower cost and higher performance compared with the existing method. A HT switch is designed and implemented for the interconnection of a set of AMD Opteron processors for building an in-a-box cluster. On our prototyping system, the result of evaluation experiments shows this approach gives the better performance.
