S'okay. I'm personally waiting to see the long-awaited post here or on another BOINC prject that says "LHC accepting new members finally!"

I sooooo wanna get in on that project.

Those who are crunching for them, which I am one, crunch through them pretty fast. The current wu's take around a hour long for me. And the graphics are pretty cool too!

For the moment they really don't need more people. But there were hints that they may open back up in the not to distant future.

Keep an eye on the front page and it the work level starts to stay up ... they are more likely to be interested in adding participants.

Heck, my expectation with the LHC@Home experience we may see other accellerators looking at the success they have had ... and they may want to jump into the pool too ...

Even better, might we see that after they go "live" on LHC itself, that we may run the expiriments in our "virtual" space before they burn actual time onthe machine? :)

Fun stuff to think about ... now if only I can buy the new PowerMac ... :)

I have had the same thought - as well as maybe they'll add an app (or more) to the boinc project that analyzes the results of actual LHC runs - then LHC@home would not only be a simulator, but also a science app :)

It can't be soon enough for me, as it is a true science application.

Look at all the DC projects that popped up after the success of SETI...

I'm a little confused by that statement Paul, it was my understanding that the data we would be given would be "test simulations" - by that i mean they would simulate adjustments to decrease the degredation and increase the "signals?" (i forget, i'm tired, just got off work, sorry, memory lapse)

> Fun stuff to think about ... now if only I can buy the new PowerMac ... :)

Again, I agree 110% (well, may not with the Mac part), if and when I do get in, BURP and Pirates are history.

It and Einstein@Home are my favorites as I am a hard physics nut instead of the "soft" bio-sciences. SETI@Home was my starter, but I have to admit that only the Astropulse part really has my attention, but as it stands now I will have to do the one to get the other ... or, at least that is how it stood the last time I asked Dr. Anderson.

> I wish that we at least could be on a waiting list...

Good suggestion ... have you sent it to the admins? ... too late ... I just did and I get the royalties from the concept ... sorry ...

> Look at all the DC projects that popped up after the success of SETI...

Yes, my thoughts exactly ... though there were a number of them that were up at that time too ... I know I looked at CPDN and the year long models did not warm my heart. I tried a couple of the math ones but either they did not stay up and running or there was no way to tell if they were really working. So, SETI@Home Classic worked, you could see it work and so there I stayed (to the tune of 61,177 work units).

My point is that it may be possible to create simulations that could show that an expiriment would work, or that there is no way it could work ... before you use up time on the system.

An example of this type of test is at the San Diego Supercomputing center, at least when I took the tour my instructor arranged, where they ran the programs on a less expensive computer that used the same machine code as the Cray. This was to proof the program and data-set so as to not waste the Cray's time on a program that was going to crash. I forget the speed difference, all I recall is that it was huge, but, running it for "x" hours on the "toy" made sure that the time on the Cray was not wasted for a program that would not run in any case.

This is especially interesting in that at that time, we were also told that the time on the Cray was booked for up to 2.5 years into the future. Of course, my memory of that tour (back in the late 1980's roughly 1987-88) may also be, ahem, amiss; but there may be another voice out there lurking that can set me straight if I got it wrong.

Well, if you are just buying a PC to do BOINC on, I can tell you I am real happy with the Dell Dual-Xeon 3.4 GHz machine I bought for roughly the same price. But this is not only to be a BOINC machine, it is also to be the one I work on (if I can get back to working again ... I have been unable to do much of anything for a long time now; though that might be a good spur to, ahem, "force" me there ...).

Paul thank you for brightening my day :-)

I wish I could have been a part of Astropulse, but unfortunately, I didn't have internet at the time...

I would love to have taken that tour myself

Last year I took my youngest daughter to the Mid-America Science Museum here in Hot Springs, and I was amazed at all the displays that were interactive...

Why couldn't they have had something like this when I was a kid? (I even crawled through the "termite exhibition" tunnels...

We both had a good time (i'm tempted to throw in a link to show what all they have there)

What really made me feel good about the whole experience there, with her, was that science can be fun.

I could go on, but i am tired and i desperately need to go to bed...

btw, i know very little about Mac's, that's what i meant...

...is this the same system you just ordered?......(i forget the specs)

james :-) (goodnight paul, everyone in SETI-land, i'm tired)

I just bought a Dell dual-Xeon, but have been planning on getting a better PowerMac this year also. I would have bought one in place of the Xeon except I knew that the new ones were just around the corner.

So, I waited. Now it is a question of when can I order the new PowerMac ...

Re: Astropulse

This is an upcomming addition to the SETI@Home application set (well, when it gets here we will have a set). This will use the same data tapes that have already been captured with a different Work Unit size and new Science Application.

The first stage of the BOINC Beta tested the first generation of Astropulse, but now that BOINC has evolved I am sure that there will need to be changes made. The other complication was that the science person for Astorpulse evaporated before the black holes did ...

I still have a surprising 37 unstarted on 4 computers ... but they reun fast like Predictor@Home work units, they been running about an hour for each one ...

@Paul

I would like to extend a "very" large thank you here

I just got through reading thru the boards over at LHC again and I ran across your request for a waiting list.

It wasn't just a "simple" question/suggestion on your part...

I admire the fact that you stuck your neck out for those of us who would quickly crunch for LHC, who haven't been able to do so because applications aren't being accepted right now.

"50,000 wu's gone in an day..." with the current user base of 6k (i forget exact number) is certainly a problem for them now (and sure to grow with each current member adding farms, and of course with an increased user base in the future) - suggestion - smaller wu's?

I imagine it would be very easy to ignore the wishes of others, as alot of people do, and to have the attitude of "yeah, I'm in, but you're not...not my problem..."

Even when others in that board mentioned/complained about the possible "flood" of n00bs (as happens with all projects) and the questions/problems that they would create for the mods/devs - you offered a possible solution -

I can only hope that they will soon let us crunch for them. I realize they have bigger problems. I was disappointed about one idea proposed. That being - you had to be a member of a team (i can't recall all the specifics, but it was mentioned as a possiblity) - the problem that i have with that is:

I crunch all projects equally (SETI, CPDN, PP, Einstein...) - I may be wrong in my thinking here but when I join a team their preferences become mine - so i'd end up crunching more Einstein than i want to etc.... unless of course i start my own team

I'm still the new guy here and there are alot of good people and alot of good teams. Someone mentioned a few days ago about they would like to join one team, but hadn't done so because they thought others would think they were being "partial" to that team... I understand that, i wish that you could be on more than one team... (My point) With that "idea" the door is locked for individual crunchers (who crunch for more than one project) - or so it seems at this point.

In any event, hopefully it will get tossed around enough to get someone's attention and they will let some or all of us in. In the meantime, I will crunch quietly in the background...

Thanks again Paul :-)

At present, You keep your own preferences as a team member. Also, in the past people team shopped by taking their credit with them. Under Boinc, your past credit doesn't get added to the team score, only the credit you get while a member is added to the team, and when you leave they keep the credit you added while a member. At no time are your personal credits affected.

Don't be too sad about not crunching LHC. I crunched for them in 2004 and don't recall alot of problems, then they shut down over the holiday season and restarted early 2005. They had big problems, Many of the WU they sent out had a bug. It would grant "0" credit on quite a high percentage of WUs. Alot of crunching for nuttin. I currently have some LHC units that I'm crunching and hope they have these problems fixed.

Thank you for the info, i was under the assumption that preferences changed. I understood about the credit though.

I didn't want to give the impression that I was sad, no, I am quite content and very busy crunching what I have now. If and when I am able to crunch for LHC I would probably stop crunching for BURP and Pirates (not that I've done alot for them anyhow). It's not the credits that I am interested in accummulating, but it's the thought that I am actually helping a science-driven application.

I've got kids, so I learned patience ;-)

My main point was in saying thanks to Paul for his efforts on our behalf.

Actually, the thought came from something here or Einstein@Home. And since you have to be a Participant to post, well, non-participants could not raise the question about a waiting list. So, I did.

The discussion was interesting, and I stopped replying because it seemed to me the objections raised had been already addressed by the earlier discussion.

Mostly, I feel that projects that are closed to new Participants should have a sign-up list for when they open up (if ever). Hmmm, maybe that is a suggestion for the base project itself! :) {done}

Anyway, you are welcome.
