Networks of workstations and high-performance microcomputers have been
rarely used for running parallel applications, because, although they
have significant aggregate computing power, they lack the support for
efficient message-passing and shared-memory communication. In this pa
per we present Telegraphos, a distributed system that provides efficie
nt message-passing and shared-memory support on top of a workstation c
luster, We focus on the network interface of Telegraphos that provides
a variety of shared-memory operations such as remote read, remote wri
te, remote atomic operations, and DMA, all launched from user level wi
thout any intervention of the operating system, Telegraphos I, the Tel
egraphos prototype, has been implemented, Emphasis was placed on rapid
prototyping, so the technology used was conservative: FPGAs, SRAMs, a
nd TTL buffers. (C) 1997 academic Press.
