CPU/ATI GPU hybrid AstroPulse for Windows released
timiman:
Thanks Raistmer.
I'm going to use a 4870x2 only for SETI.
What are the correct settings for a 4 CPU SETI MB + 4 SETI GPU AP for <avg_ncpus>, <max_ncpus> and <count> ?
0.2, 2 and 0.02 ?

On my 2600 XT, this is what I'm getting:
07/11/2009 08:41:26 SETI@home Sending scheduler request: To fetch work.
07/11/2009 08:41:26 SETI@home Requesting new tasks for CPU
07/11/2009 08:41:31 SETI@home Scheduler request completed: got 0 new tasks

any suggestions? (GPU & CPU preferences yes on seti)

The biggest problem with these settings - I even don't know what can be considered as "correct" ones.
IMO BOINC can't handle applications of such hybrid type correctly at all, but will see what peoples will invent ultimately.
But in particular, <max_ncpus> definitely should not exceed 1.
Better leave them as I wrote above.
These numbers just tell BOINC how many app instances it can run and can it run another apps with this one or not. Best configuretion is overcommitted CPU (that is, CPU should run same amount tasks as it did before this AP app installation + this AstroPulse app) and count number for coproc should give 1 in total (with other GPU-oriented project).
That is, if you run Milkyway + SETI - set MW's count to 0.48 or 0.49 and leave count for AP on 0.01.
The number of GPUs installed should not afect on those numbers.

Set your Setiathome Preferences like this:
Run only the selected applications SETI@home Enhanced: no
Astropulse: yes
Astropulse v5: yes
If no work for selected applications is available, accept work from other applications? yes
Boinc will ask for Astropulse and Astropulse_v5 work, and since there is none available of those,
you'll be sent work from the other (unselected) applications, ie seti@home_enhanced and Astropulse_v505,
subject to what app's are listed in your app_info, and if there's any work to send to them.

corsair:
and what about x64 version?? I use not to run any x32 if I can.
Same messages:

59 SETI@home 07-11-2009 13:12:35 Message from server: No work is available for Astropulse v5
Run only the selected applications:
SETI@home Enhanced - yes
Astropulse - yes
Astropulse v5 - yes
If no work for selected applications is available, accept work from other applications? - yes
Use Graphics Processing Unit (GPU) if available - yes
Use Central Processing Unit (CPU) - yes
