500-fold Increase in Data Flow from SETI Telescope
coondoggie brings us an article from Networkworld about a flood of new data for the SETI@home project. We discussed something similar a few months ago when a new telescope array went live. The vast amount of processing power required to handle the new data is prompting the SETI@home team to make a plea for more volunteers. Quoting the press release:
"What triggered the new flow of data was the addition of seven new receivers at Arecibo, which now let the telescope record radio signals from seven regions of the sky simultaneously instead of just one. With greater sensitivity and the ability to detect the polarization of the radio signals, plus 40 times more frequency coverage, Arecibo is set to survey the sky for new radio sources."
Protein Folding should take precedence over pointless searches for noise-in-patterns.
i was kinda interested in this at one point then when I installed SETI@home i realized that it made my proc max out 24x7 and shoot up to it's load temps (obviously) and of course use more electricity. i decided that I wasn't willing to stress my equipment or pay for the electricity to run this type of software ( I do of course realize you can set the amount of cpu it uses.. but still) I think that all these distributed projects kinda try to gloss over the fact that it isn't free to participate ... and given the $100+ a barrel oil at the moment people that chose to participate should probably be made more aware of what the costs and wear and tear impacts really are.
actually I am happy to see you, however that is in fact a banana in my pocket.
Just because you think you know what people should do, doesn't mean you do.
This issue is a bit more complicated than you think.
There's a logic error here, I think. By this logic, we should do nothing except the very highest priority thing in our life, and society should pour all of its resources into the very most important priority. For example, we should all live in a thatched hut, eat weeds and grubs, wear the untanned raw skins of animals (or just go naked), and slave 18 hours a day so all our labor and energy can go into....whatever the single highest social priority is...curing cancer, fighting war 'n' injustice, whatever.
Which is silly. The goal of life is maximize overall satisfaction, not accomplish one single highest goal. It's important to rank your priorities, of course, both as an individual and as a society. But the notion that because A is "more important" than B implies ipso facto that A should get all the resources and B should get none is maximally silly.
Indeed, it's kind of OCD obsessive to always be focussed on pursuing the Top Goal, the kind of thing that when we see people doing it in practise -- giving up everything, including enough sleep and good nutrition, to, say, play World of Warcraft and become the biggest baddest player -- we conclude they need to do some growing up.
Fine, I'm burning cycles running a project that may (heck, when it comes to SETI, probably) won't see any tangible results.
But how is contributing to a project that was the basis for mainstreamed distributed computing any more wasteful than blowing 9 hours a night on WoW? I'd love to see a breakdown of the increased energy usage from a high-end CPU and a good video card vs. a PC that's on anyway and running BOINC when it's idle.
Screaming "carbon footprint!!" about something as trivial as BOINC is the real waste. Here, I've swapped 80% of the lights in my house for CFL's, and I burned 10 bucks worth of electricity last month (with an electric heater and 4x computers in the house no less!) does make me green enough to spare some processor cycles now?
There are some people that if they don't know, you can't tell 'em.
