1. Overview and Summary

1.1 Scope of this Report

  This document is a summary of the research activities and results for the eight month period, 16 March 1986 to 15 November 1986, under the Defense Advanced Research Project Agency (DARPA) Submicron Systems Architecture Project. Tech- nical reports covering parts of the project in detail are listed following. these sum- maries, and can be ordered from the Caltech Computer Science Library.

1.2 Objectives

  The central theme of this research is the architecture and design of VLSI sys- tems appropriate to a microcircuit technology scaled to submicron feature sizes. Our work is focused on VLSI architecture experiments that involve the design, construc- tion, programming, and use of experimental message-passing concurrent computers,

and includes related efforts in concurrent computation and VLSI design.

  Additional background information can be found in previous semiannual tech- nical reports [5052:TR:82], [5078:TR:83], [5103:TR:83], [5122:TR:84], [5160:TR:84], [5178:TR:85], [5202:TR:85], [5220:TR:86].

1.3 Highlights

Some highlights of the previous 8 months are:

All sections of the Mosaic C designed and laid out (sect ions 2.2.3 and 4.1).

Cantor programming language operational and in use (sections 2.2.2 and 3.1).

Joint projects initiated with two companies to build prototype second generation "cubes" (section 2.3).

New results in compiling multiprocess programs to self-timed VLSI designs (sec- tion 4.2).

2. Architecture Experiments

2.1 Cosmic Cube Project

W C Athas, Michael Lichter, Wen-King Su, Chuck Seitz

  The Cosmic Cubes and Intel iPSC continue to run very reliably, with researchers at Caltech and at other DARPA sites using them for application programming projects. Usage has been moderately heavy.

  Our own most intensive use has been for event-driven simulations of designs for the second generation message-passing multicomputers (see sections 2.3 and 3.4).

  A system supporting Cantor, a fine grain concurrent object-oriented program- ming language, is now available and in regular us...
