December 2008 Meeting Notes

Compiled by Dave Jaffe

Contributions from Kevin Appert and others


Coffee and a Chat


Matrix Multiplication in a Massively Parallel Processor Array - CH Ting
"My goal is to perform matrix multiplications of two 1000x1000 matrices. I think this can be done very fast if I have a processor array with 1000x1000 processing elements and sufficient memory in each element. I need suggestions on how to invert matrices and diagonalize matrices (eigen values and eigen vectors). So far, I have not found good ways to solve linear equation problems with a large processor array. All available algorithms work well only in serial operations."


Due to the holiday Stanford campus closure, we may be carpooling to lunch venues on University Ave in downtown Palo Alto.

SVFIG Treasurer's Report - John Rible


Forth Day 2008 Lessons Learned - All in attendance


RoboDevelopment Conference & Exposition Slide Show - Dave Jaffe
Dave will present a slide show of this year's hobbyist / trade expo.


IntellaSys Chips - John Rible
"I'm proposing that SVFIG buy 50-100 bare chips to resell (may not be the proper wording for sales taxes, etc.) with enough mark-up to cover costs of mailing. IntellaSys (CEO Chet Brown) has agreed to sell them to SVFIG at $20 each if we agree to limit any one person to 10 or less and accept responsibility for all support / return issues (that's why IntellaSys is selling through distributors). This would occur in January, after the chips have been tested."

Kevin's comments:

"We'll discuss and decide! $20 * (50 chips) = $1000"

"I'm not sure we'd really sell this many so if you aren't going to be at the meeting, express your interest NOW! Let me know how many you want either by posting to the SVFIG list or directly to me at: forther-at-comcast-dot-net "
