My 7970 was running kernel 21 and outputting results in 1500-2500 seconds for most of September. Recently the WUs have been taking 2700-4000 seconds with some requiring 5000+. I've experimented with kernel 22, but the results seem similar.

Have there been any changes to the WUs or is the issue my drivers, settings, etc?

Yes, WUs changed a few days ago. The project was running through "2*..." range, but it's running through "2^2*..." range now and run times per WU can be 30-40% higher than before.

For me tasks the are averaging at least twice as long as before with no increase in credit. I like collecting those useless credits so I'll be moving most of my boxes elsewhere...good luck

I'll try to remember to wave when, sometime next year, I pass you in project credits!
For science!

Not everything credits, let's Science :)

Hi guys!

Yes I've noticed it's getting harder atm as we moved up to "2^2*..." and discoveries of new number has almost stopped.

Sergei, when are you expecting us to to hit that "range" when it would be possible to find new ones and could you please explain why?

...just planning to put some more in to find them, but electricity ain't cheap over in Finland and I want to hit that 100 000 found ones as my next goal =)

Judging by the distribution of known pairs in "2^2*..." range, I don't expect many new pairs until we start "2^2*11*..." subrange which we'll reach somewhere in the beginning of December at current speed. But I plan to request adding Amicable Numbers to main BOINC projects list (both on BOINC web-site and in BOINC client), so it'll hopefully attract some more users.

P.S. Don't worry, there are still ~1,388,000 amicable pairs below 10²⁰ left undiscovered, so they will add ~2,776,000 to user counters of found pairs (each pair is found by two users).

Just as I answered before, the project has now reached "2^2*11*..." subrange which is relatively rich with new amicable pairs.
