Yes, credit granting still weird.
But it should not affect "science" as long as not too much peoples would leave because of credit weirdness.

считает 30 минут, прогресс 0%, загрузка гпу 97%(со спадами(на 2-3 секунды) каждые 4 минуты до 85%)- это нормально или убивать процесс?
ЗЫ: перезапускал боинк - тоже самое.
ЗЗЫ: разобрался - перезагрузил комп и все заработало нормально.

I finally got a validated result and I think my wingmen are going to be disappointed

http://setiathome.berkeley.edu/workunit.php?wuid=658407398

apparently 11 hours worth of work is worth more than the 72 given. I have to assume that my GPU crunching killed the normal granted credit


That 72.85 Credits was from a Wu that only took 1,214.74 seconds (20 minutes) to complete on your GPU, so 72.85 Credits isn't too bad for that length of computation.

Admittantly the first ten validated Wu's Credits suck, or paired with someone doing their first ten Wu's, which are both your wingmen in this case,
but that improves once you're done at least 10 validated Wu's, or paired with someone who has had ten validated Wu's.

I have not received any AP WU,s yet but credits look similar to the credits received on Seti@home Beta AP.s. Wich if you remember varied over a wide range.

Стоит проверить, не было ли рестарта драйвера (в системных логах).
Я такой ситуации со времен ранних версий у себя не встречаю. "быть такого не должно" :)

It's true, ATI AP should claim just same amount of credit as CPU AP does. It's server's credit granting weirdness, not app's one...

В логах ничего не нашел. Видуха считала милкивей, когда загрузилась ВЮ астропульса расчет переключился на него.

The credit granted to Skildude may not be as weird as it looks. I noticed this
Found 30 single pulses and 30 repeating pulses, exiting.
and maybe the 72 something credits is just where the lowest claiming one stopped.

I have an host which currently runs Einstein on CPU and this ATI Astropulse ap on a cheap ATI board (HD4550 512M--only 80 stream processors).

At the moment I am typing the valid tasks list has unusually many results--as the ones returned when the servers came back up have not mostly be deleted.

I've been getting credits in the 600 to 800 range for the ATI AP work, save for obvious premature terminations. I'm not aware of punishing my quorum partners in credit.

For this 80-stream board the initial performance tuning options shown in the sample ap_info fragment work for crunching, but give a pretty bad user experience on almost any simple desktop interaction, and make, for example, Netflix streamed movies so jerky as to be unwatchable.

This could be addressed by specifying no use of GPU for crunching during interaction, but hoping to preserve more crunch, I've been slowly backing down the performance tuning values, and am currently using this line:

<cmdline>-ffa_block 512 -ffa_block_fetch 128</cmdline>


These values are not likely ideal for this board, but seem to have lost not very much and perhaps no crunch performance, while giving a much better user experience, though I think the graphics are still probably compromised appreciably.

I suspect the 80 stream boards want lower values here than the serious graphics 800 stream processor boards do.

I'm looking forward to being able to try the lunatics ATI multibeam ap when it goes public.

I didn't see a specific mention of running down work units already in progress or previously downloaded. Is this something that is so obvious that I shouldn't be asking the question or can we safely set this up as long as we stop all science applications before making the changes to app_info?

Yes if you have any Astropulse onboard you can run the work down then install.

With correct app_info editing one not need to empty cache, all just continue to work as before + new app will be available. Hence no mention of this action.
But if you unsure the safe way to go is not to empty cache, but to make backup of BOINC data dir, disable network connection do upgrade and then, if all go fine, re-enable network connection.
With empty cache and invalid app info you have perfect chances to trash much more tasks than your initial cache was. So safe way is just as I described, not to empty cache.

Thank You for the feedback.

And would also like to say Thank You for the all of the hard work in creating GPU applications for those of us stuck with ATI cards.

Right now I have eight AP tasks that have started so will play it safe because I do not want to waste all of the download time should I do something stupid (which happens every minute of every day). The extra four are in progress because of a shift to high priority mode.

They're going to have to check the credit. I'm assuming the validator isn't giving full credit for the WU and is just looking at the completion times. I'm only getting 400-800 credits depending on the WU/blanking. These are valid results but getting substantially lower credit than expected

I just turned in an AP with zero blanking and got 665.16 credits for it. This was run on my CPU. http://setiathome.berkeley.edu/result.php?resultid=1724416785

Perhaps we have a new credit system for the AP's. I'll go back to abusing animals and hiding for Johnny Law.
