I'm on the rise. After falling from ~3,900 to ~2,800, I'm slowly going up. My pending is still going up as well, but there's more validated now.

Likely wingmen are finally catching up with you so older WUs you had completed and were "validation pending" are finally being reported as valid.

Still I would expect you RAC to be much higher if you are processing with all four cores 24/7.

I'm not. I process with 3 cores, to leave one core free for the GPU at Einstein. If I don't, the BRPs there run in days, instead of hours.
I also don't run 24/7 as I cannot afford to do so. So I run when my electricity is cheap(er) than other hours, meaning during the week between 9pm and 7am and during the weekend (Saturday + Sunday) all day and night.

Since I started to do it like that, I've managed to get money back from my energy company at the end of the year, instead of having to pay up to €1,500.- extra.

I also have my systems off or hibernating during the day. We've got 3 computers, only one runs BOINC. There's even times I forget to turn my system on at night. Happens. I don't mind.

watch the RAC fall and fall and fall and fall. and also noticed that with the new version of the op app unlike the old op app i was using i actually have to turn off gpu crunching to actually use the system.

I would post about your system availability problem in the installer thread.
There may be some settings that could help you with that.

I have not tweaked anything other than running 2 tasks/GPU, so I don't have any experience with those settings yet.


I remember reading some time ago about keplar cards and vlars, and a program to autoabort them. do you know what the program was and if it works with the new version of boinc

Allow NT has been set, enjoy!

RAC 115,000 on May 29, 2013; now 72,000 on June 9, 2013 and still falling; in fact the slope of the curve has not changed.

Mine will keep falling until I can get the current gpu back online and add a 2nd gpu, I think the current gpu needs some better heatsink compound on the gpu, some Arctic silver 5 ought to do the job and maybe thinner thermal pads too, instead of the thicker pads that are there now, I'm awaiting an email on the pads from Zotac, so until then the card stays as a display card for its own good.

Dear friends,
Maybe my question is to some another thread, but... Can somebody explain, why these new applications are so slow?

They do more work than the old ones did, so they take longer to finish.

Credits pro task are almost the same, so the amount of operations may be approximately the same too. So where is this "more work"? In additional if-then-else, which are checking "is really true 1+1=2" or something similar?
And all these if-then-else are outside of the flopscounter?

Credit per task is way down on what it used to be. That's a function of how credit is calculated, not the work done.

Additional processing, which will be explained in the News thread when the project admins have time.

Credit new has no clue what so ever what to do yet. This is a great example here : http://setiathome.berkeley.edu/workunit.php?wuid=1261682117

In time the estimates and credit will even out, this has always happened when something new came around here at Seti.

Do You say: "Credit is not proportional now to the amount of useful work"?
I did not understand, but Thank You anyway. :-)

A lot of people in many forums say: "Credit new is a random number generator". Brutal, but near to the truth.

So we crunch on anyway because we want to know.

I reckon it's falling faster than that.

Based on daily data, refer other thread, I am heading towards a RAC of 45% of previous (under v6).

I have not read all documentation about Creditnew, but from what I have understood from other posts, it is a way to at least partly gauge the credit granted to the average crunching power of participants.

When I got to know that optimised applications would be incorporated in stock, I, like many others, imagined that this would decrease the edge of the people running on optimised applications. The vast majority of people would have now effortlessly benefited of the higher efficiency of these applications.
So far so good, natural and good for the project.

What I thought regarding the credit, was that this would bring the average credit higher for everyone.
Instead, perversely, being the average crunching power increased, it must have been interpreted by the system at least partially as "V7 WUs are easy to crunch" and has thus reduced the allotted credit.
Given that in average optimised applications gave roughly double throughput, now we are getting roughly half credit.

My opinion is that if you run 1.000 miles, those are still 1.000 miles if you go on foot, by car, by plane or by rocket.
And it sounds strange to me that now for the same amount of work we get much less credit.
It is also not good for the whole project, since this way there is no means to see how much computing capabilities are increasing in time. If every time there is some kind of big improvement the project is normalised, there is no way to appreciate that and we get a solid, sad flat line (if you are lucky, since now we are nose diving. AND THIS IS WRONG BECAUSE THE PROJECT AS A WHOLE HAS very ROUGHLY DOUBLED ITS COMPUTING CAPACITY AND IS GETTING INSTEAD HALF OF THE CREDIT, i.e. 1/4 of what it should get.).
