Very interesting.
I did some standalone benchmarking of CUDA MB while CPU running 4 another BOINC tasks (not AP though, einstein@home ones) and didn't see any degradation in CUDA MB elapsed times and speed.
But it was quad w/o HT.
Do you use V10 or V11 CUDA MB build from this thread or stock one?

I'm using the V11 that was referenced a few pages back. I'm now had a full 24 hours of crunching with HT more or less disabled (thru BOINC anyway). AP processing time dropped from about 17-20 hours down to 10-11 hours consistant. CUDA WU's are still pumping out in 10 minutes solid compared with 15-20 mins prior.
This seems to confirm what you were saying about HT rigs crunching slower, which makes since since the four HT "cores" are not true physical CPUs.
So far it would seem that my overall production has increased. Due to the decrease in time to process AP units, I'm not that much slower on AP than before, and cuda is running close to twice as fast....not bad.

I wonder if someone could help.
I've got a quad 6600 with a 9600gt cuda gpu running Win XP pro with bionc 6.6.20.
I'm wanting to run AP wu's using an optimised app on all 4 cpu cores and stock (or opt i'm not bothered) app for MB608 wu's on my GPU.
I've tried "Raistmer's_opt_pack_V10a_x86_SSSE3_MB_CPU_GPU_team" pack but when I restart bionc it drops all my cuda wu's but processes my AP wu's great. This is what I've been doing:
* Stop network activity in bionc
* Close bionc and check processes have stopped
* Back up my bionc dir
* Drop opt V10 apps in to seti data directory - incuding packaged app_info file
* "number_of_GPUs" file is '1'
* cc_config = <ncpus>5</ncpus> (4 cores and 1 gpu)
* Restart bionc
But its annoying how I cant get it to run cuda especially as everything works great, all be it slow, with just the stock apps from seti.
cheers Rich

In addition this is my host: http://setiathome.berkeley.edu/show_host_detail.php?hostid=4819034
I have just tried again with the V10 and updated my nvidia drivers to 182.50 and haverecorded the error message in bionc as:
19/04/2009 17:27:29 SETI@home [error] No app version for result: windows_intelx86 608 cuda
This message occurs for each cuda I have in the cache. all AP restarted fine

Raistmer:
check your app_info file. It should contain corret app name (the same you have in project folder)
