At the Crypto '86 conference I presented a new variation of the Quadratic Sieve algorithm for factoring large integers. The variation has been programmed on a STAR configuation of SUN-3's using ethernet connections. I can demonstrate that N machines run N times as fast (less perhaps 1-2%) as 1 machine. The algorithm requires miniscule I/O between the central host and its satellites and it partitions itself in a natural way such that each satellite can work totally independently of the others. I don't have 200 SUN-3's to hook together, however. I have submitted a paper describing the work to the Journal of Supercomputing. Bob Silverman
