Hi all!

I have to wonder. . .

Are people getting discouraged with the project and leaving, or are they leaving for other reasons? (For example, could it have to do with the warm weather in the northern hemisphere?) If people are leaving because they're discouraged, then they're creating a vicious circle. The more who leave, the longer validation takes, which will in turn cause more people to leave, which will cause validation to take even longer.

Anyway, I just thought I'd throw that out and see what everyone thinks.

I believe we had a similar happening last year about this time, although I forget whether it was discussed here or over at SETI.

University semesters are finishing up for the summer and students are shutting their systems off and going home (or whereever). Also, warm weather in the N. Hemisphere causes systems to run hot, so people shut them down (A/C can be expensive!). You'll see a pick-up come August/September.

Message 62573 in response to message 62571

I think the "number of active hosts" statistics could be misleading. For example there's a single user http://einsteinathome.org/node/192772with a couple of thousand computers and only very few of them were actually ever sending results , so the others will drop out of the statistics gradually and will drag down the number of active hosts without influencing the total FLOPS power of the project, which remains quite constant between 75 and 80 TFLOPS.

You will see FLOPS drop in the next few hours because the validator happens to be down at the moment, tho.

The "percentage of completion" statistics is also not quite accurate, I guess, because it measures progress as a percentage of the number of workunits completed. But I have the impression that the different sizes of workunits are not evenly distributed and that we are getting less of the shorter units at the moment. This might add to the perception that units take longer to validate.

Recruitment of new participants also is quite constant (except when SETI@HOME has problems).

So I don't think that E@H is running short of participants right now, but a summer slowdown will happen.

A shortage of active participants would manifest itself in a drop of granted credit per day which should be visible in the boincstats graphs like this one:

LOL. That user joined the same day I did and has dominated in first position 'sign-up date'" stats. Maybe now I can slowly gain some ground on them....only 5(+-5) more years to go!!

With any luck its because the devs are fixing the different OS validation bug... [Quickly crosses his fingers]

But it is an issue that the "floating point speed" is dropping a bit and also the "percent done"-curve is not linear as in the previous run and rather also getting flat.
I have also withdrawn my clients until the project gets his problems fixed.

Where did you take your clients instead?

Hang in there Bikeman, with any luck it'll be on of your hosts that finds a gravity wave!!!

Finally got around to updating the BIOS on this system. I was wrong about the Apr 2001 BIOS date. That's what CPUz reports and is probably the chip date. Before I did the BIOS update, the MB reported the BIOS date as 3/25/02. After the update it reports the BIOS date as 10/28/02.

CPUz v1.40 still doesn't show SSE. I get approx. the same performance as listed below for Einstein. Don't know what Seti will show as they are DITW (dead in the water) right now. Time will tell. I may need to replace the MB (if I can find one...and in the right price range).

Well, in case anybody's interested, I finally did the MB upgrade on this system and CPUz now shows the chip as SSE capable. With all the glitches with that ECS K7S5A MB, I'm glad to be rid of it.

We had a fairly substainial drop around this time last year as all the college students came home and various people shut down extra boxes to control thier AC bills.

Two of four are off here too. From the two left, one is only runnig about ~1h/day instead of 24/7 and my X2 will stop crunching as soon as I receive another zero credits result. The chances therefor are pretty good.

The informations given to the users at this project is far too low for me to accept. I see no rational reason to hold off one of the project members to give daily(or nearby) updates on what's going on. That's only 5 min. of time which the volunteers imho realy deserve.
