The ``Telegraphos'' Project
Telegraphos - from the Greek words ``tele'' (remote) and ``grapho''
(write) - is the largest current R&D project in AVG, carried out in
cooperation with the Pleiades
Group. Telegraphos is a project to design architectures and
build prototypes for high speed computer communication, in workstation
clusters.
