<b>Home Computers Search for Gravity Waves</b><br /><br />LINK<br /><br />Scientists searching for waves of gravitational energy that stretch space and time will soon be seeking the public's help in analysing their data. <br /><br />Researchers at the Laser Interferometer Gravitational Wave Observatory (LIGO) hope to enlist up to a million personal computers in their search for sources of the waves, which have long been predicted but never seen. <br /><br />Their distributed-computing scheme, set to launch this month, aims to be one of the largest projects of its kind ever created. The software is already in beta testing.<br /><br />Albert Einstein's general theory of relativity lays out the idea that gravity distorts space and time. As a test of his theory, Einstein predicted that waves of gravity would ripple through the cosmos. Some claim such waves have been spotted indirectly, from observations of how paired stars influence each other's orbits, but nobody has seen them firsthand.<br /><br />Since 2000, researchers at LIGO have scanned the sky for tiny shifts of space that would prove Einstein's theory. The project is being built by the California Institute of Technology and the Massachusetts Institute of Technology on two sites, one in Livingston, Louisiana and the other in Hanford, Washington. It uses a system of lasers and mirrors that can detect a shift in space as small as the width of an atom.<br /><br />Bell ringers<br /><br />LIGO's best hope for detecting gravity waves is to spot a cosmic source that sends out regular ripples of gravitational energy. A source such as a spinning star made of neutrons would set the detectors ringing like a bell. <br /><br />The problem is that the detectors pick up an enormous number of unwanted vibrations. "It's a needle in a haystack problem: 99.99% of the data is noise," says Bruce Allen, a physicist at the University of Wisconsin at Milwaukee. <br /><</safety_wrapper>

Thanks Zav.

I might help, but I think folding@home would yield results that could save lives. <div class="Discussion_UserSignature"> </div>

Thats right odysseus, Join folding at home instead, as someone's sig says "the life you save may be your own".<br />See ya on the team! <div class="Discussion_UserSignature"> <p> </p><p> </p><p>----------------------------------------------------------------- </p><p>Wanna see this site looking like the old SDC uplink?</p><p>Go here to see how: <strong>SDC Eye saver </strong>  </p> </div>

 

[zavvy]

Can't you do both?

 

[earth_bound_misfit]

Possibly, F@H uses unused PC cycles so the two programs may fight over these. BobW might know more about this. <div class="Discussion_UserSignature"> <p> </p><p> </p><p>----------------------------------------------------------------- </p><p>Wanna see this site looking like the old SDC uplink?</p><p>Go here to see how: <strong>SDC Eye saver </strong>  </p> </div>

Hi, Zavvy. Sorry for the late answer but I had to remember to search the folding forum and my brain is pretty one-track lately <img src="/images/icons/smile.gif" /><br /><br />From this post at the folding forum:<br /><br />http://forum.folding-community.org/viewtopic.php?t=7182&highlight=seti<br /><br />The question was:<br /><br /><blockquote><font class="small">In reply to:</font><hr /><p>I recently downloaded F@H, and Seti@Home. I run them both at the same time. Because Seti and F@H always steal the CPU of each other, i set F@H to only use 50% of the CPU, and let seti take the rest. F@H still uses the CPU up, but it has been running all day and still says 0/600 done (0%). Is my computer just extremly slow or is something going wrong? <p><hr /></p></p></blockquote><br /><br />The best answer was:<br /><br /><blockquote><font class="small">In reply to:</font><hr /><p>The default priority of Seti is higher than the default priority of FAH, so unless you adjusted the priority in the advanced settings of FAH, Seti will take 99% of the resources, and FAH will take 50% of whatever is left over. Setting it to "LOW" (if you have the Console client) or "slightly higher. . ." (if you have the GUI client) should put FAH and S@H on an almost equal basis providing you reset FAH to demand 100% of the resources. <p><hr /></p></p></blockquote><br /><br />I see from your link to Einstein that it is from the same guy that did seti so there is a good chance that Einstein will hog the CPU if you try to run them both but we won't know for sure until it is ready. <br /><br />I have been thinking about getting another computer for Einstein because I'll feel guilty taking one of my computers away from the space dot com folding team. I've been following LIGO from the <div class="Discussion_UserSignature"> </div>
