The SiCortex family of Linux cluster systems takes High Performance Technical Computing (HPTC) a step beyond conventional clusters. SiCortex concentrates on power-efficient design and simultaneous tuning of silicon, microcode, and system software to deliver outstanding application performance per dollar, per watt, and per square foot.
This paper describes the SiCortex interconnect fabric, its software interface, and the communication software, including the Message Passing Interface (MPI), that uses it.
