The organizers have not settled this question but spoke of making commercial parallel systems available and also of providing a high speed network for communication and experimentation among the participants.

The neural session resulted in a draft master plan stating that they hoped to build a 10-TCUPS machine in 10 years. Last spring, Hitachi demonstrated a working 2-GCUPS wafer scale neural system. Thus 10 TCUPS appears to be a realistic target within 10 years, and certainly not an unexpected one. One change coming out of the workshop was that this committee has decided not to validate the system on real applications but only on “novel functions for applications,” i.e., application building tools.

The optical computing systems session emphasized the optical interconnect technologies and the supportive device and materials processing. The sentiment was that this type of work needed to be done before realistic sizings of processor architectures could be made. Of the 13 Japanese proposals, 8 were really expansions of and capitalization on existing industry (6) and university (2) optoelectronic device R&D. There was a ground swell of opinion that the session should report back only on devices for interconnects and leave the other two assigned topics (optical digital and optical neural) for other subgroups (namely, massively parallel and neural systems). The session moderator agreed with the technical reasoning, but said it would have to be discussed after the workshop. Virtually all the major Japanese companies, except NTT, were represented with these types of optical device proposals.
