Modified SETI MB CUDA + opt AP package for full GPU utilization

So here's what i did. Installed boink 6.4.5 (widgets version 2.8.7) fresh on machine one, and repair install on machine 2. then unpacked Raistmer's_opt_package_V7.rar

With V7 pack your CPU will capable doing only AP SETI. And now servers send very small amount of AP tasks. Maybe it's worth to connect to another CPU-oriented project like Einstein@home.
On host with single GPU V8a should be used, not V7 one.

Yup...hold the press...there it is : 2 cudas and one astropulse running at the same time. Absolsolutely fantastic. I'm fascinated. Cudos Raistmer, cudos and cudas!!

Actually, for dual core + dual GPU host it should be 2 CUDA MB + 2 AP tasks if all was installed correctly ;)
You have quad with 2 GPUs so it should be 4 AP tasks and 3 CUDA MB tasks.

Yes I would assume that would be the case, but there was only one Astropulse unti available on my list. I was stunned to find on the quad core that the unit was completed in 10 hours cpu time. normally a unti would take days. I'm still finding that cuda processing speed decays overnight. After returning to the consoles after 12 hours, dual gpu processing which normally ticks at 0.100 or more, has slowed to 0.010..and for the first time the single gpu machine had stopped and was "waiting to start'. Restarting boink brought everything up to speed again. Both boinks are set to 'run always. not sure why it's doing that, but i'll roll back the single gpu machine to 6.4.5 and report what happens.
Quad CPU and dual GPU should present 4 Astropulse and 2 cudas correct? (just wondering if you made a typo)
Dual gpus on nvidia chipset, single gpu on intel chipset.
Stoffe:
Running the V7 app. my CPU-cores won't do any work, like Raistmer stated, but my problem is that my 9800gx2 will only run one core (and Boinc also reporting only 1 GPU core).
After reading Bloort's post about GPU-speed I get even more confused. It takes about 20 minutes for my GX2 to run one WU. Bloort talking about 8 minutes, on a 8800 GTX (witch is an older card than my 9800gx2).
What have I done wrong?
Using 181.22 drivers, SLI-mode disabled, Vista 32bit, Q6600.
