We present novel hard- and software that efficiently implements
communication primitives for parallel execution on Workstation
clusters. We provide low communication latencies, minimal protocol,
zero operating system overhead, and high throughput. With this
technology, it is possible to build effective parallel systems
using off-the-shelf workstations. Our goal is to develop a standard
interfaceboard and the necessary software for interfacing any
number of computers, from a workstation to a cabinet full of
workstation-boards
