ok, let me think about this for a bit. Not that I think it will make a difference but you could lower the CPU value back to 0.5.

Something else that is preventing those CPU APs from running.

Edit...

Sorry if this is too basic, but Activity is set to Run always, Use GPU always as well?

I'm sure you did, but I'm starting from scratch to see if I can think this thru..

Zalster,

I looked at my APs results and compared them to yours. It seems yours run with 10% cpu and mine seem to run at 100%. Same as Cliff's. Am I missing a setting? My MB cuda tasks run the 10% cpu. I'm running my 970's .33gpu/.5cpu.

ap_cmdline_win_x86_SSE2_OpenCL_NV.txt

-use_sleep -unroll 28 -oclFFT_plan 256 16 256 -ffa_block 12288 -ffa_block_fetch 6144 -tune 1 64 4 1 -tune 2 64 4 1 -hp


That is the only setting I have for the APs

Edit

Use notepad to edit the ap_cmdline_win_x86_OpenCl_NV.txt file in setiathome folder

Besides the -use_sleep parameter, switching to the latest r2887 app might help. I've noticed that the CPU times for AP on my xw9400 just about dropped off the charts with r2887. That box has a couple GTX 660s and a couple GTX 750Tis.

Did you notice a difference in completion times for the AP units?

Virtually identical times, maybe even just a hair better, on 3 of the 4 GPUs. For some odd reason, though, one of 750Ti cards is taking about 50% longer. I haven't taken the time to research that yet. I suspect something else is going on there.

Not meaning to shift this threat off topic I just had a look at one of the tasks and noticed that they were running for over an hour for an MB task this seems really long. I run 2 tasks and a time & the Max I have seen a task run for I think is about 15 minutes. Settings are 0.5 for both GPU and CPU. I have the same as you

Raistmer's fix works ok,

But you have to be really specific when messing with that app_info.xml

I've had it fail on 2 machine, lucky the first machine took it and I've just been copying the file on a thumbdrive and doing a copy and paste

Edit

to correct file name

Who's tasks Speedy? Mine or someone elses? MB task or AP task?

looking at the xw9400 block diagram it has four slots that are physically PCI-E x16 but slots two and four are electrically just PCI-E x8. so if one were to assume that the 660s were faster then they should go into slots one and three? of course you may already have it populated that way

I've had it fail on 2 machine, lucky the first machine took it and I've just been copying the file on a thumbdrive and doing a copy and paste

I assume you mean app_info.xml. Yeah, that file can be tricky if you make a typo. I think there were just two places it had to be changed, though, and I guess I got lucky the first time.

Yes, sorry..

Carrying on 2 conversations at the same time, lol I'll correct my post to reflect app_info.xml

I don't remember the slot numbers, but the 660s reside inside the case while the 750Tis are attached to riser cables that hang out the back. I didn't change that physical configuration when I upgraded the driver (350.12) and the AP app (r2887), so the odd behavior is probably something else. I just haven't taken the time to look into it yet.

Todderbert & it is 4263183147 I was referring to

I'm guessing here but I bet he was crunching both several MBs (2) on that GPU when an AP started on there as well.

You can run both on a GPU, but the AP will be accelerate and finish faster than usual but the MB will actually slow down to a much slower.

That would be my guess.

Todderbert would know for sure.

Yes, I noticed this behavior when the AP tasks would start the MBs would begin to slow, got worse when 2-APs and 1-MB was running. I applied the command line configuration that Zalster provided, noticed a change right away with my cpu utilization falling back down to a normal level.

If I were to add this new app to my folder and make the changes to app_info will it dump my current AP tasks?

Very possible.

I'd wait till you finish this AP run then do it. That way you don't lose any of them.

If you lose some MBs, you can always get more.

The primary danger is simply making a typo. However, there really aren't that many entries that need to be changed, as I recall. Just the .exe and .cl references. In my app_info.xml, it looks like there were 4 of each. The structure is very confusing.

if you mess up app_info, you will lose your cache

sometimes when i do the change i lose one task because it was half processed by the old app and half processed by the new app

so if you wanted to make sure you kept that one task, just suspend all the non running tasks, finish the remaining tasks, then shut down boinc, change the app out, fire everything up again
