I just learned about this program over at the Infidel Community Forum.

http://www.physics2005.org/events/einsteinathome/index.html

There's also Folding@Home

http://folding.stanford.edu/

At Folding, you can join the Humanists, atheists, and Freethinkers team.

I'm not sure what the point is, when we have recently launched satellite (bah, forgot the name) that will collect this data up to until 2006 and the resultant laser measurements will either prove or disprove the gravitational whirling of the space itself...

That satellite is designed to detect the effects of "frame-dragging", but I don't think it will detect gravitational waves, which is what Einstein@Home is trying to do.

Should anyone be interested, the Einstein@Home project is now open to the general public. You can sign up and download the client here: http://einstein.phys.uwm.edu/

There is more information about the project here: http://www.physics2005.org/events/einsteinathome/

Shameless plug: There is a "Wicked Old Atheists" einstein@home team (started by me) that you can join if you want to. The team home page is here: http://nodeity.com/woa/ The URL for joining the team is on that page.

But of course, as Jesse points out, this will measure frame dragging, not gravitational waves. To measure gravitational waves, another project is underway at the U of W: LIGO (http://www.ligo.caltech.edu/), the Laser Interferometer Gravitational Observatory.

About 6 years ago, I joined the SETI@HOME project. When the screensaver kicked in, we could hear the hard drive buzzing as each parcel of data was crunched and recorded for transmission back to the SETI people.

This went on day after day.

Two months later, my hard drive crashed. Somewhere in the dark corners of my mind, I felt that this was not a random event - the little green men (or the searchers for same) had done the deed to the drive.

So now I'm waffling about joining this effort.

And ... as of this posting, I'm about 1/3 through my first WU! :thumbs:

I suspect you didn't have enough physical memory; you were thrashing your virtual memory. This is definitely a problem.

Two months later, my hard drive crashed. Somewhere in the dark corners of my mind, I felt that this was not a random event - the little green men (or the searchers for same) had done the deed to the drive.

That was probably the cause, given that you were deficient in physical memory.

So now I'm waffling about joining this effort.

Well, if you see your HD light go on and stay on when you're doing the calculations, you should definitely turn it off until you figure out why it's hitting the drive too hard.

I've had people say I was deficient in other aspects of my physique, but my memory is usually pretty good.

Oh - wait, never mind.

Yes, I've got a newer machine now, more of everything. So maybe I'll give it a try.

I see hard drive activity only when the program downloads new data packets. Give it a test run, but I'd not sacrifice my hard drive to the cause either.

First WU finished sometime yesterday, and the second is underway. I'm ranked #88 on our team right now, but am really just excited to be doing something like this.

Oh, I've got a 1.8GHz processor working on this right now.

I am getting serious competition from I C Unicorns! :notworthy

I need to check all my computers to see if the F@H client is running properly and maybe upgrade some of the older Pentium IIIs to Athlons 64s lol.

Yeah, I had 15 dual 3.6GHz Pentium 4 extreme edition machines at my disposal over President's day weekend ;) so I put them to work. WU's done are gonna slow down now for a while.

Hey,

I want to join in as well. One question though:I have an upload limit that I can't exceed... how heavy is it on upload bandwidth/total data transferred?

Thanks

The bandwidth used is negligible. What it needs most of all is CPU power. Fortunately the client runs in the lowest priority so it rarely interferes with your normal computer processes.

At our current rate we are about 3 weeks from 1,000,000 points.

Are other people still active? When I ... oh, wait a minute. Nevermind I just figured it out. I saw this:Active processors (within 50 days) 1
Active processors (within 7 days) 1
... on my user page and it only just hit me that that represents my processor(s) and not the teams'*. I thought, briefly, that I was the only one who'd been active recently. D'Oh! Silly me!

Anyway, this is some pretty cool stuff! I've only completed 4 WUs, but I'm on my way up (2 spots in the last week)!

*which I now see has 101 processors working recently
