V9 of modified SETI MB CUDA + opt AP package for full GPU+CPU utilization
Geek@Play:
Problem is that sometimes work is actually stopped or appears to be stopped. Perhaps it's not but I don't know if it is stopped or not because of the "Waiting to run, 0.04 cpu's, 1 CUDA" message in Boinc Manager. I have proven that the work is being done while showing that message in Boinc Manager. It is impossible to know the true state of the work with this message. That is the big problem. I just cannot tell the state of the work with that message in Boinc Manager even though it is being crunched.
This state cannot be overlooked. You will be flooded with complaints if this is released.

It released already. V9 includes (among others) mod that rejects to stop CUDA app when BOINC wants to stop it.
This should decrease probability of having 5 CPU apps running on quad but idle GPU.
Probably you see effect of this mod.
As I already said you can see if app actually runs and making progress by looking into state.sah file.
My main concern to ensure full utilization of both CPU and GPU. What BOINC thinks or writes about situation and how it interprets situation - not my concern.
This mods actually hack BOINC and cheat it. When BOINC will be able to run both CUDA MB and opt AK_v8 simultaneously on the same host the need in these team mods will disappear.
Geek@Play:
I installed using "AstroPulse & CudaMB, 1+ GPUs, no Team (req SSE3)". I do NOT have the <ncpus> in the cc_config file. I am therefore running 4 AP work units on the CPU's and 1 CUDA on the video card. This is exactly the configuration I want on my quads.
To be unable to monitor the progress of the CUDA-MB work in Boinc Manager is unsatisfactory. You seem to feel that it's ok since it is crunching the data. I with respect, humbly dissagree.

But keep in mind that I haven't ability to test it still. My GPU host running x86 Vista.

13 downloads at moment I write this.... And no single repost if it runs or not :-\

Been running this 64bit package for a few days now on my i7, and everything seems to go just fine. Seeing a nice speedup on the x64 AK also.

Only been able to run the new V9 app for 24 hours or so (after the upload issue have been cleared off and no completed unit put at risk). So far so good. With V8 there will be some intervention from Maik script to stop the app hang (where it got stuck at 0:00:00 CPU time) but experience with V9 seems very positive.
Thanks and great work.
