Spring here too so the temp in our apartment is no longer ~60 F. As a result, my computer is running a bit warmer (~42-43 C vs. 38-39 C). Of course I only have 8 fans on the thing. :wink: I recently replaced some of the fans with quieter ones so it doesn't sound quite so much like a P-51 taking off.

Following the instructions on the first page should still work. One thing you might want to try is to download and run Prime95 before you work on any WU's. If you run the torture test that comes with the program, you can see if you have any hardware problems that might cause Einstein@Home to give incorrect results. What kind of machine do you have?

You shouldn't have any problems - I've got in running on a Duron, two Semprons, and a Celeron. Basically, no problems running under Windows XP.

Ok I've joined up now, not sure what i'am doing here.
But i've got it crunching some numbers I guess.

Screensavers kinda cool.

I dont seem to be on the team list yet. Do I have to wait for my first work unit to be done and uploaded?

You should show up on the team list as soon as you've gotten credit for your first workunit, just give it a little time.

Ok no probs, looking forward to doing my bit to beat the US navy.....

[edit]

ok got my first workunit done, it says "ready to report" and it's started another one. What do I do now?

[edit]
scratch that, worked out how to report the data

Welcome to our 50th member, Amadeus!

Your first credit has already been granted here!

Just a couple of small points: the "ready to report" thing takes a bit of getting used to, since the BOINC client automatically uploads the result as soon as it's finished, but doesn't report credit at the same time. (different servers.) But it will update your credit and remove finished work units from your "Work" tab the next time you download a new WU. If you are on broadband, you can minimize the time between finishing and reporting by setting your E@H General Preferences "Connect to network about every..." setting to a small number, like .1 days.

But in spite of this, and after 6 months or so of BOINCing, whenever I see an un-uploaded WU lurking, I reflexively "update" manually. Greed, it's wonderful.

Also, the screensaver is indeed excellent, but several folks have reported problems with lockups and/or slow exit of SS mode with it, so if you have a problem, one of the first things to try is choosing a different SS in Desktop properties. Unfortunately the "Show Graphics" option, which should show the SS in a window during normal use, hasn't worked for the last several versions of the client. The SS, being very computationally intensive, may also slightly lengthen your time to do a WU.


****************
When I get time here, I will try to edit the first post of this thread to reflect the fact that folks need not --- indeed, perhaps should not --- read this whole thread to get started. There is some good info buried here, but a lot of it is cheerleading by myself & reports on the rise and rise of the BABB team. And a few, "my box is bigger than your box," type of deals. 8)

As I hope you've found, Amadeus, someone here is always glad to help out, so post away.

*****************
As far as a sticky goes, it would be good, but since this thread seems to get bumped every few days anyway, maybe it is visible enough? I tend, I'm ashamed to say, to ignore stickies after I've seen them a few times; and too many is bad for the readability of the overall section; but feel free to ask the BA about it.

A bigger problem, IMO, is just the length of the thread: maybe some folks are scared off, thinking there must be huge problems running Einstein@Home with such a big thread. I will try to address this in editing the first post as well, but as always, all ideas on increasing membership are welcome.

***************
And let me add my (still premature) congratulations to all of you for our place in the Top 40: The hits just keep on comin'. =D> =D> =D>

I just got last month's electric bill and after running Einstein@home for 14 hours a day, almost every day, my March bill was almost exactly the same as it was for last March. I do shut the monitor down overnight. So, for me at least, the increase in my electric bill is neglible.

Computers don't really use that much electricity. I have kept three computers running 24 hours a day for several months and my electric bill has basically been the same as always.

That's what I thought. I've seen some concerns here and on the Einstein@home forum about increased electric bills, so I just wanted to dispel the idea that running Einstein@home increases the electric bill.

Just turn your monitor off when not in use and that cuts a big chunk of the electricity that a computer uses.

What is the screen saver? I mean what does it mean?


I'm going to leave my computer on always from now on....


THe 20+ pages scares me away definetly

how do I change the propertise- I can't seem to find it.

Hi mickal,

There isn't an item in the client menus for screensaver; when you installed the client, there is an option to make BOINC your default screensaver. If you don't check this box, after installing, there should be a "BOINC" screensaver option when you do "desktop|Properties|screensaver," that is, it is a standard Windows screensaver.

(Another reason for not reading this whole thread was I was totally wrong about this much earlier; kept looking for SS in the client. ops:

And mickal, rereading your post you ask "What does it mean?" So instead of the above, maybe you are looking for a description of the SS? It's at the bottom of the E@H page.

Hope one or the other of these answers work?

To change your properties, goto the E@H homepage, click the "Your Account" link. About halfway down there is a "Preferences" section, click the link for "General."

BTW, I followed my own advice and change to ".1" days & it still hadn't downloaded a new WU when the last one was 50% done, so I had to change back to ".3" days, which has always worked well for me. It depends on how long your box takes to process a WU, I think, so you'll have to tweak the number til you get the best results. Bottom line though, no matter what setting you use, the client will eventually download a new WU, and when it does, it reports your credit for any that you've finished since last time you updated.

****************
I agree on the screensaver/power issue; I use a "none" screensaver & my monitor powers off after 10 minutes, so this works well with running 24/7. But to clarify, my comment about the SS using resources was more that it may take a few extra processor cycles that could be used for crunching E@H. Ideally, when you are running 24/7 and not actively working at the box, you want as few processes running as possible, so E@H runs fastest. It's easy to obsess about this though, and probably that's what I'm doing when I say the screensaver may slow down E@H.

How about someone start a new thread when we officially hit the top 40? It could publicly self-congratulate us, briefly describe how to join, slyly note the BA's endorsement of the team by mentioning he is in the top 4 of 40; etc. Then invite folks with questions to post to the new thread & let this one die.

It would be good to have someone with lots of E@H credit and credibility (posts) in this forum do this: Evan? SarahMc? tmosher?

It's looking like it takes me 6 and half hours to finish a work unit.

Is this an average amount of time?

__________________

takes me days

__________________

Takes me 20 hours. Depends on what PC you have (or other computer of course), and then again, if it is on all time (20 hour is CPU time, so if I would only have my computer on for four hours a day, it would take five days per WU... ).
But if you finish it in six hours, then you're pretty fast! I believe your average credit was 200+ as well, so that's very good (most people with higher averages are probably running E@H on different machines at the same time). The average average credit (is this average²?) seems to be around 100.

Well I've got here at home an AMD Athlon 2600+ with a gig of ram...

Didnt think it was that fast...

__________________

Here are some rough numbers for various AMD processors:

Duron 1.3 - around nine hours per WU
Sempron 2600+ - six 1/2 hours
Sempron 3000+ - six hours
Celeron 1.3 - eleven hours

__________________

I assume that's an Athlon XP 2600+. Those are pretty decent processors.

1.60GHz Pentium 4 Mobile - 15 hours
Athlon 64 3000+ overclocked to 2.35 GHz - 5 hours, 20 minutes

Does calculation time depend on your CPU? I thought it sent you as much data as you could digest in about 15 hours. So slow PC's would get less data in one package than large ones. Correct? 8-[

My P4 3 GHz with 1 GB RAM (hyperthreading) takes 15 hours for 2 packages. It's my home PC, so it isn't on that much (lately).

__________________
To the regular visitor of internet bulletin boards it is clear that it's an excellent idea your parents get to choose your real name.

I think that the amount of work contained in any one WU is about the same. For example, using other benchmarking programs (like Super Pi) I have found that my computer at home (Athlon 64) is nearly three times faster than my work computer (1.6 GHz mobile P4). As you can see in my post above, that's about the time difference for a WU. Depending on your settings, a faster computer might download more WU per day, but each WU requires approximately the same number of calculations.

E@H is very dependent on the CPU math coprocessor. The Athlon XP FPU is much more efficient than any of the Pentium FPUs. It runs about twice as fast for the same CPU clock.

__________________
When I am done here I think I will go create something from metal.

FYI: 2.4 GHz Pentium 4, 1 GB RAM, Win2000; about 9:45 per WU

I just changed the scheduling to run full-time, up from a scheduled 18-hours/day. My average went up over 30% -- mainly because the PC is not used at night (other than crunching E@H data).


There is an outside chance I can add my home computers in May.

I noticed the Navy's average has increased, while their number of members has not. Now we might not make the Top 40 before up-and-coming Greece United gets there. :x

Of course there are quite a few in the Top-40 that could be knocked off, eventually.

Hmm, glad I didnt go for pentium. To be honest the main thing that put me off was that stupid "do de do dee" music adverts have to put in every time it's mentioned. Stupid stupid marketing idea.

I should revise the times I posted:

Duron @1.3 GHz = 10.5 hours per wu
AMD Sempron 2600+ @1.925 GHz = 6.75 hours
AMD Sempron 3000+ @2.0 GHz = 6.6 hours
Celeron @1.3 GHz = 12.25 hours

All except the Duron machine are run 24/7 on Einstein - the Duron runs 24/7 but I also use it for internet and word processing functions (around 2 hours per day).

All four machines are running 256 mb under Windows XP SP1.

When I first started running Einstein, I got a wild hair and started building cheap machines (roughly $250 each) to add additional horsepower to the effort.

Tom

Where are those machines Travis? I will not accept the excuse that you're busy or actually trying to get real work done. [-( :wink: Greece United is rapidly gaining on us. We should get to the top 40 before they pass us, but...

Speaking of positions....

Just noticed that i'am no longer at the bottom! \/

BTW how are people getting the stats to appear in their sigs here?

Still not in the top 40 for total credit (we will probably get ther for a short time, even though there are now at least four teams behind us catching up on us), and we have slipped from 28 to 34 in the average credit (meaning that we still can get to 34 in total in the long run!).
But the good news is that 2 new members have joined (up to 51), so someone is our member number 50. Congratulations to our mysterious prize winner =D>
