HyperTransport in High Performance Applications

The essence of today's high performance computing platforms are clusters of high performance processor or processing systems linked together using high bandwidth interconnects such as InfiniBand or 10Gb Ethernet. A key factor in system level performance is achieving low latency between the processors and clusters.

By using multiple processors with HyperTransport links, developers of high performance computing clusters can provide very high performance systems that are easily scaled upwards in performance. A processor cluster of four processors, each with its local caches and memory can utilize a HyperTransport switch to connect to each other and shared memory. Each processor has the full bandwidth available for accessing its own memory and can use the high-speed HyperTransport link to access the memory of the other processors.

BTW: HyporTransport používa aj CRAY vo svojom novom low-cost modeli superpočítača XD1.
