V10/11 of modified SETI MB CUDA + opt AP package for full multi-GPU+CPU use
br83taylor:
ok thamnks for clarifying that.
didn't bother changing the cc again.
however did managed to get a few MB units, however bonic didn't start them, carried on doing the three AP jobs.
i tried suspening one of the AP units, thinking it would go onto the next MB unit, but it didn't, it just tried to start the next AP unit??
ended up having to suspend 10 AP units before it got to the MB work unit and started that, which it did pass to GPU for processing.

Just out of curiosity, sorry if it's a stupid question. I'm kinda new to this.
I'm using BOINC v6.6.18 and NVIDIA driver v182.08 on WIndows XP x64. I have QX6700 and 3 GPUs (GTX295+8600GTS). I've set the <ncpus> option to 7 (4+3). and so far it run it seems to run ok but rather on a slow side.
I'm crunching on SETI@Home Beta and none of these tasks run on CUDA. All my SETI WUs are setiathome_enchanced 6.08, aren't these WUs supposed to be run by optimized CUDA app according to the app_info.xml? If so, then I might have a problem? I concurrently run GPUGRID project and it used all 3 CUDA tasks while SETI Beta taking 3 running slots but none show it it's utilizing CUDA GPU.

With Boinc 6.6.x you don't need an <ncpus> entry in a cc_config file, just remove the entry, it was for Boinc 6.4.x to fool it it into thinking it had an extra CPU, Boinc 6.6.x knows about GPU's and doesn't need the work around.
setiathome _enhanced_6.08 is the Cuda app, and please don't run optimised apps on Beta unless they are for special testing of new unrealeased apps,
I 've recently been matched up with this user's computer on Beta, he's running optimised Astropulse 5.00 r103 and trying to Validate against astropulse 5.04 (ie astropulse_v5) , Which isn't very helpful there, and a PM hasn't helped.
Run the optimised apps on the Main project, and visit this thread to get the special app_info for Boinc 6.6.1x.

Hi,
i need ask.. what the best build now ? ( for X2 Athlon and GTX 260 ) ? ( Cuda computing priorytet )
?

Hi,
What is the setting for using both cores in a GTX 295?
I have one GTX 295 and using the default setting of 1 in number_of_gpus does not seem to utilize more than one core, as the computations equals a GTX 285. A setting of 2 will spawn 2 GPU executables, but one of those will have a full CPU utilized continously, so it's not working..
I have seen references to various tweaks and also references to both cores running, but not become any wiser as to what is the correct combo of settings to utilize both cores on the GTX 295.
Regards
Morten Ross
