SETI@home download time

I run the SETI@home screen saver b/c I think it’s a cool concept (group computing or something?), and I want to be the guy whose computer “discovered” little green men. That’s a whole other can of worms.

I want to know why a work unit that takes hours and hours and hours to process, only takes about 3 seconds to download raw and upload processed. I’m sure my terminology is far from ideal. Basically, what (in terms of d/l and u/l times) seems to be a few words, my computer is treating like an encoded encyclopedia.

Cable modem and Pentium 4 1.8 ghz with 256 Mb RAM by the way.

Seconds to up/download the raw data on my office T1. Takes about 12 hours to process each unit on my P3-450 at work though.

Well, you could read a paper here, but it’s pretty simple. Remember any of your math homework - one line to ask, one number to answer, and you’ve got 3 pages of scribbles in between. :wink:

Each work unit is about 300K bytes, hence the quick download. The computations done to each unit, however, are pretty intense.

One line question, one number answer, three pages of scribbles… I like that analogy!
