I strongly agree with you. I've founded a little team in Spain three month ago. I becomed very excited with this particular project and, during all this time, I was trying to involve more and more people in the search of gravitons. I'm pretty satisfied because I've gathered a dozen members who belong to the modest Astronomical Society of La Coruna and our team have got a very good rank in the Top Teams board (251 at the moment). Nevertheles, nobody of us knows anything about the progress of the proyect, if we are doing an effective work or if we are really wasting our computing time. I've read somewhere that the LIGO and GEO interferometers are not fully functional yet and they are still in the calibration phase improving the accuracy and sensitivity. I really miss some kind of gratitute and information.
I would like to suggest that the dead line for the WU be delayed one more week like Seti or the units be reduced because not every body have a modern computer and are not willing to leave it on during the night. I think a lot of people give up the project because of this (I have had some experience on that) and therefore a lot of cpu time is being lost. I do believe that the philosophy of distributed computing is not having loads of very fast multiprocessor computers working all around the clock, the most of the people are normal persons with normal computers.
Thanks

Folks,
On the Science board I've put in a bit more detail than is in Bruce's front page announcement. I don't often have time to read beyond the Science board, so if you've got science questions (including the progress of the project) that's a better place to ask them. A newsletter or something similar will probably happen at some point, but right now everyone involved is working all night writing and fixing code. Remember, this particular distributed computing project is pretty new and it's run by a pretty small group.
Hope this helps,
Ben

Ben
And this will be very much appreciated. Please, please find the time (15 - 30 mins) once a week to give us an insight into what is happening behind the scenes. Please link to it from the front page so that the many who think they don't have time to delve into the message boards, do, in fact, get sucked in while browsing the front page.
We know you're all busy behind the scenes. But I'm busy too and yet I've found the time to get about 32 boxes crunching for E@H to the tune of 280,000 cobblestones, awarded + pending. I don't care about the credit but I do care about what my contribution has achieved towards the science outcome. I'd very much like to know and I'm sure many others feel similarly.
I've also found the time to attempt to help many other users with problems for which I feel I can offer some assistance. There's nothing like regular progress reports to make it seem much more worthwhile. Please don't take this in any way as a complaint. One of the reasons I joined up in the first place was the visibility of Bruce in the message boards and the willingness of various staff to keep us informed as to what is going on. E@H is certainly better than S@H on that score. Now that Bruce has quite understandably eased off his post rate, a regular update on the Science board would be very welcome.
Cheers,
Gary.

I just feel the same, no critics, no complaints, just an advice to keep everyone motivated to crunch.

Gary,
My apologies for not doing a good enough job providing feedback to E@H contributors. The truth is that I'm not sure what's expected or wanted.
It's the last week of classes at UWM, after which I hope to be able to post a fairly detailed summary showing the preliminary results of the initial S3 analysis and explaining how and why we've cleaned the data and are redoing this better. I've been putting a lot of my time into finding and fixing various BOINC scheduler bugs, and into doing the post-processing of the Einstein@Home results which has kept me from spending time actually writing about it. We are also working hard at making the changes needed to analyze LIGO's S4 data set, which is significantly more sensitive than the S3 data.
Do keep in mind that the analysis we are doing is probably less mature than that of any of the other @Home projects, so it's taken a large effort to put everything into place for this.
So the bottom line is that I expect we'll have some preliminary results posted by the end of May.
Cheers,
Bruce

Bruce,
No apologies are needed as your post count of 444 is indicative of your willingness to "get your hands dirty" and that in itself has been a tremendous boost to helping people sort out problems, and to disseminating useful information about bugs, etc. I guess when Ben was kind enough to take the time to explain some of the "behind the scenes" information in his article in the Science forum, I seized on it as a perfectly good example of exactly what is needed on an ongoing and regular basis.
We know that you are busy and we are encouraged by the progress being made in sorting out the scheduler. In most cases I don't think people are too upset with the fact that fixing one bug often seems to lead to unpredictable problems elsewhere. I think that people are very pleased with the stability of the science code and realise that BOINC problems are often beyond the capability of the project itself to anticipate or correct.
However, the details of the science itself are the things that interest many people. The things you mention in your 2nd paragraph are exactly the details that people would be interested in. In your third paragraph you mention less maturity of your analysis. What exactly do you mean by that?? What do you need to make the analysis more mature??
You peobably have regular team meetings to discuss progress, focus on problems, direct attention towards things that need to be done at particular stages, etc. No doubt some of the topics discussed might be suitable for more general dissemination. A short article, like the one Ben posted, summarising some particular aspect of the science that was topical, would probably be fairly simple to do and would do wonders for the sense of involvement of your contributors out here in the far corners of the globe.
I look forward to your "End of May" report card :).
Cheers,
Gary.
I too have been wondering

I too have been wondering about how the results are being used. But it does sound like the team is very busy just trying to get everything to work well. So I decided to do a google search and see what was out there. There is a lot of info available. It varies greatly in the degree of background you'd need to understand it. I personnally am unfamiliar with the symbology and some of the math used in the technical papers, so the simple presentations are better for me.
The google search terms I used were "S-3 ligo results"
Here's a couple of results I found interesting though dated.

Here's a more recent bibliography:
http://www.geo600.uni-hannover.de/results.html
It looks to me that so far they have been checking the instruments out, increasing sensitivities, and setting upper limits on the possible size of the gravitional waves. My impression is the the sensitivities are getting good enough that the upper limit results will be able to help sort some of the gravitational/pulsar theories.

I will be working on this next week. I think that you (and other E@H contributors) will enjoy it. In spite of all the glitches, E@H is performing very well.
