Paper Abstract

Multi-level electronic integration of massively parallel computers leads to latency effects and 110 bottlenecks. Free space optical interconnections might be a good alternative to interconnect processors located on face to face PC boards. When the processors are integrated in MultiChip Modules, an obvious improvement to the latency problem can be making the MCMs to communicate from board to board. We present here part of a project which was led in collaboration with the CEA ILETIIDEIN(Commissariat a l'Energie Atomique ) in Saclay ( France ). The LETI DEIN was in charge of the conception of the parallel architecture, of the design of the MCMs and of the electrical architecture. The Optics Department of ONERA CERT has to make the choice of the optoelectronic components, their caracterization and hybridization.
