Abstract

I volunteered to write this report during the SIMD panel session held on 2/9/95 at Frontiers '95. All panelists cooperated by sending me their transparency masters. A draft report was prepared based on these transparency masters, position statements published in the Frontiers '95 proceedings on pp. 466-469, and my own notes. The draft was e-mailed on 3/17/95 to the panel organizer/moderator and the panelists for their comments. This final version of the report is based on comments and markups received through 3/31/95. I have drawn from the panelists' ideas freely, using quotation marks only when including their statements verbatim.The panel consisted of both academic and industry experts in the field of massively parallel systems (see the table below). All but Tim Bridges, who is currently involved in a large-scale software development project for the MasPar MP-2 SIMD architecture, have built working SIMD machines. The vast practical experience of the panel was quite evident in the insightful presentations and interactions. It is indeed a privilege for me to have worked on this report.
