The Synfinity Interconnect: A Low Cost Infrastructure for Building
High Performance Multi-Processors

EE385B Computer Architecture Seminar
April 14, 1999

This talk introduces Fujitsu System Technologies (FJST) and
its primary product, Synfinity. Synfinity is a low cost, high performance
interconnect with 1.6Gbyte/s/direction bandwidth per link and 42nS router
fall through time. Synfinity connects to standard interfaces, such as PCI
and Intel processor busses, allowing low cost, scalable servers to be built
using standard high volume (SHV) components.

First, I will describe the network architecture, including our recently
announced Synfinity II physical link which transmits at 1.25Gbit/s/wire.
Secondly, I will describe the architecture of our shared memory (CC-NUMA)
system, the Teamserver M831i,  which connects up to eight Intel Pentium II Xeon
processors running Windows NT.
