Hi there,

all of a sudden i start getting errors in APs, which i don't understand:
http://setiathome.berkeley.edu/results.php?hostid=157931&offset=0&show_names=0&state=6&appid=
The app is r2399 and is running on driver 342.50 on this computer:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=157931
Any help/suggestions highly appreciated... :?

Aloha, Uli

Looks like app crash after finnish to me.
It happens when your host lacks ressources IE is busy otherwise during boinc_finnish call.

Try to increase -unroll and ffa_fetch values.
You are using -use_sleep so thats recommended.

Yes, it's elusive "crash after finish" bug that plagues mostly Nv builds.
Unfortunately, it didn't eradicated so far and shows itself time to time in AP 7.03 NV too.

I experienced it on my host too with high number of crashes... and suddenly all crashes disappear for few weaks. Maybe host reboot helped, maybe some Windows updates....

I plan to take next attempt against this bug soon but for now we must just live with it. Try to reboot host.

As another possible fix try to add -cpu_lock option and see if there will be any crashes with this option active?

EDIT: also you could try to help in debugging by participation in beta:

Ok, the other Aps went thru fine.

But i have an interesting observation for the developers of OpenCL on NVidias:
If i run only one AP per GPU, i can only get to exactly 50% GPU load, that's why i let ran 2 per GPU. Now on the last AP left running alone on the main GPU, i had the 47-50% GPU load. And now for the WOW: The moment i started DVB-C streaming, the GPU load got up to nearly 100% - and no, it's not because of the streaming, the calculation with one WU is really crunching faster, if there is some "background load" running parallel on the same GPU. The moment i stop the streaming, the GPU load drops to values below 50% and the crunching is SLOWER! I'm stunned! :? :? :?

Aloha, Uli

Check GPU clock for shader/memory..
Also, it can be not hardware effect but software one. Change driver priority of smth alike. Even it can be CPU effect - higher CPU (not GPU) power state allows quicker CPU response to driver needs. It's all connected...

I just tested r2667 of the AP executables and it totally fails on XP:
http://setiathome.berkeley.edu/results.php?hostid=157931&offset=0&show_names=0&state=6&appid=
...back to r2058 for now. :/

Aloha, Uli

I hope that this fixed in latest AP v7 builds.
Soon 7.04 will be deployed and will see.

Im getting AP errors in droves. On my I7 920, This host

I will reboot and see what happens. I just recently up garded this machine to the latest lunatics app.
Is it my machine or something else.

Try r_2667 please.
You can get it from my website.

Update.When I noticed the erros I had 6. when i went to rebbot I had 9. after reboot ( which was a power down and then back on ) I had 11 errors.

@Mike- Is what I have going on, The same thing affecting others?

Edit- I have suspended work untill I get some advice. Erros are up to 14 now so a reboot didnt help. So far my i7-3770s are error free.

It happens on some pre fermi cards.
Nothing to do with crash after exit.

So I should try r_2667? And should I abort my AP work?Seeing as its erroring outanyway?

Yes, it should be fixed in 2667.
You dont need to abort work.
Just change the name of the app in appinfo.xml after copying the files.
Stop boinc first.

Your best bet is to Stop BOINC and run the Old Lunatics installer and Install r1843. You don't have to abort any work.

Are you a Lunatic now ?

Or you could download and run the v0.42a installer from the link in my message 1560695

No, and unless James has progressed quite a bit since the last time I tried to have him do a manual install, He should stick to Installers.

Ask him about the time I tried to get him to install a CPU App from Your site.

Or you could download and run the v0.42a installer from the link in my message 1560695

That is the one I downloaded. I made sure to use the app for the 200 series of Nvidea cards.

Well as my APs were self destructing and I dont have more than 35 APs left on this host. I will try most anything.
Now downloading the r_2667 and then changing the name of the app in the app_info.xml file sounds daunting. But how many times is that r-2667 named in that file? Or do I need to scan the whole file changing the app names?
Id like to try what ever works.

I guess 6 times.
3 sections 2 times each. IIRC
