sentences:  This interconnection was closely reflected in the architecture of the CM2 of Thinking Machines Inc., the first massive-parallel system in the VLSI era.His 1991 paper with Zhou and Kang on interconnection delays in VLSI was awarded the 1993 "Darlington Best Paper Award" by the IEEE Circuits and Systems Society.In the late nineties, (in joint work with G. Bilardi) he confronted the problem of the physical limitations (space and speed) of parallel computation, and formulated the conclusion that mesh connections are ultimately the only scalable massively parallel architectures.
