I downloaded and installed the app_config.xml file and it started ripping thru the V7 GPU wus nicely at two @ a time. The it started doing APs on the GPU and suddenly the room cooled down again (humour there.. is winter in Aus so like the heat *grin*)

SO, what should I add to the app_config.xml file so that it crunches two APs at a time or is this stretching it?

(And yes, am aware that it'll be a simple answer, but it is the simple answers that sometimes lead to greater questions.)

LOL - you dug back a long way for that one - 8 pages, on my settings. Here it is en clair for reference:

<app_config>
   <app>
      <name>setiathome_v7</name>
      <gpu_versions>
          <gpu_usage>0.5</gpu_usage>
          <cpu_usage>.04</cpu_usage>
      </gpu_versions>
    </app>
</app_config>

You need to edit it (use notepad).

Keeping the outer <app_config> ... </app_config> structure intact, make a duplicate copy of the middle block (from <app> to </app>, inclusive).

In the new section you made, change 'setiathome_v7' to 'astropulse_v6'. You might well want to increase the <cpu_usage> number for AP, too. Anything 0.51 and up will free a CPU core when running two AP tasks.

Thanks for the quick reply. We Wombats are renown for out deep digging *grin*

So can I then just save the file without stopping boinc? or should I stop, save file and then restart Boinc?

(See? en clair to one is muddy waters to another *grin*)

Well, Wanted to give the Brains (ALL OF THEM) the ego rub we all need at one time or another *grin*

Oh and these last four posts are on page four for me, so wasn't that big a hole. Just had to remember which burrow to dive into LOL.

You can edit and save the file while BOINC is running, no problem.

When you have finished (and proofread your work), go to the 'Advanced' menu in BOINC Manager, and choose 'Read config file' - that's it, no stop/start required.

Dumb Wombat remembered reading somewhere that the file could be saved without stopping Boinc... and so now have two APs going at once, having had Boinc read the new app_config.xml file. Weirdly though, it says it (in boinc) is still using .04 CPU, yet double checked config file and it stats .04 for V7 and .51 for AP6.

Maybe should bump up the CPU usage for AP, but shall see what tomorrow.. er today brings when I check in 8 hrs.

Thanks again to all Lunatics and associates for their fine work and prompt replies.

BOINC does not update that part of GUI until a complete restart of the client itself, but it will be using what you specify.

I have driver 314.07 for my Nvidia graphic card but I don't know if it's updated with a v7 aistub. How can I know or see this?

Did you run the Lunatics installer 0.41 ?
If not no of course.

This infos are only for ATI/AMD cards?

How should be the cmdline settings for NVidia cards:

GT430: compute units 2 - 3 - instances per device 2
GTX460: compute units 7 - 2 - instances per device 2
GTX580: compute units 16 - 1 - instances per device 2
GT630: compute units 2 - 3 - instances per device 2
GTX650Ti: compute units 4 - 3 - instances per device 2

- like this above?

Thanks.

I dunno...
I have been using the .txt file entries for my NV cards and they seem to be working OK.

"Freedom is just Chaos, with better lighting." Alan Dean Foster

This infos are only for ATI/AMD cards?

There are five separate .TXT files distributed within the installer:

For AstroPulse applications
ReadMe_AstroPulse_Brook.txt
ReadMe_AstroPulse_OpenCL_ATI.txt
ReadMe_AstroPulse_OpenCL_NV.txt

'Brook' are old, low-performance (almost obsolete) ATI cards
The other two files are for current ATI and NVIDIA cards, respectively.

For MultiBeam applications
ReadMe_MultiBeam_OpenCL_ATI.txt
README_x41zc.txt

'x41zc' is the code number for the NVIDIA (cuda) application: the other file documents the ATI equivalent.

Make sure you refer to the documentation for the right application.

(but now you ask, I do note that the examples for 'high end' and 'mid range' cards in the OpenCL_NV file seem to look like ATI model numbers. I'll refer that one back to the OpenCL team.)

Philip, the above should help others

If you wish, you could also add
GTX295: compute units 30 - 1 - instances per device 1

I have tried 2 instances with criteria set as 1 above however there were to many video issues and the system was unusable. I have not tried 2 instances at 2 above yet.

There is also an app that you can download, GPU Caps Viewer, that should help people with seeing how many compute units their GPU cards have.

cheers

I did a lot of benchmarking on a 6670 (6 cu's) and I found out that -unroll 9 -ffa_block 2048 -ffa_block_fetch 1024 worked best with <count>.5</count> (ie running 2-up)

Diff architectures ymmv.

Any news?
I understood this like this, that you ask there .. (or I'm wrong?) - if the recommendations are also meant for NV cards.
If not, how are the recommendations for NV cards?

I took the infos about the compute units from the 'stderr output'.
SAHv7 & APv6 's <stderr_txt> show the number of CUs.

Pre-Fermi cards like 8xxx, 9xxx, 2xx series, can run only 1 WU/GPU.
I tested on my GTX260 2 (APv6) WUs/GPU, the calculation times increased for each WU.
So just 1 (SAHv7 & APv6) WU/pre-Fermi GPU.

AFAIK, the WUs are not calculated really simultaneously on GPU cards.
The hardware jump from one WU to the other WU, this feature is very slow on pre-Fermi cards.

Every time I try and use Boinc 7.0.64 x64 with a driver older than 296.10 to crunch with on a video card, like 266.58 and 275.33, these two drivers won't load a wu into the video card with lunatics cuda42, am I using the wrong cuda with these drivers or is something else going on? Since 296.10 reports compatibility with cuda42 and I'm setup to ignore the sleep bug by default, since after 9 hours the card downclocks, the temps are in the 50C range and the card is at stock speed of 732MHz, after the downclock the speed is 405MHz, I've replaced everything except the motherboard, the cpu and the 3 drives that I use and I doubt the cpu or the drives make any difference, the motherboard is from 2009 and the last card that didn't downclock was a 200 series card, the card I'm trying to use now is an EVGA GTX570, a 1570 and the heatsink is clean as is the fan since I did that before I installed the card a couple days back. I also run MSI Afterburner(I've used EVGA precision, no difference, downclocks happened there too), I've tried drivers from 301.24 to 326.xx to no effect, I use BoincTasks 1.46 and I've tried with just BoincManager(no difference) and of course I use Lunatics_x41zc_win32_cuda42.exe too, for 9 hours everything is smooth running, then bam, down to 405MHz and wu's that took 16 to 24 mins now take over an hour to complete... I set the Nvidia control panel to prefer maximum performance and that doesn't seem to help any, fan is on Max of 85% right now and the card isn't overclocked. I can't put new thermal pads on the card yet since I don't have any right now and I'm broke until the 1st, all I could do right now is install new AS5 on the gpu, but that seems point less since I can't replace the pads yet and the temps aren't even 59C usually.

I found no infos about CUDA versions here: http://www.nvidia.com/object/win7-winvista-64bit-266.58-whql-driver.html
http://us.download.nvidia.com/Windows/266.58/266.58_Win7_WinVista_Desktop_Release_Notes.pdf - .PDF file

- and here: http://www.nvidia.com/object/win7-winvista-64bit-275.33-whql-driver.html
- but:
http://us.download.nvidia.com/Windows/275.33/275.33-Win7-WinVista-Desktop-Release-Notes.pdf - .PDF file - here they say added CUDA v4.1.

So with this both drivers (266.58 & 275.33) you can let run max cuda32 app - cuda42 will not work.
