Not sure where this ought to go, but these two groups look best. Since Berkeley has just acquired a Cray, and I like playing with large integers (100+ digits), having software to use the hardware that makes the Cray go fast to deal with these becomes of interest. A quick glance at the problem makes it look like you can do 1400+ bit adds in 1-2 nanoseconds/bit using the vector hardware. Anyone got this (other than the NSA, who probably doesn't want to let me have their code :-)? Anyone interested in it should I write it? Thanx, <mike
