CPU/ATI GPU hybrid AstroPulse for Windows released

[MarkJ]

I updated my drivers (using a ATI OpenCL beta v0.2) and have successfully managed to pickup and process a Hybrid Astropulse. unfortunately Beta is down at the moment so I can't report it. It seemed to run through fine, but had nothing else running on the GPU at the time.

So after much struggling with the Catalyst drivers I finally managed to get some crunching done on my Radeon 4550 but it seems to be relying on CPU quite a bit as you can see in the screen shot.

Is that because I use the NO DOUBLE version and so all these operations are performed on the CPU instead?
Any chance of support for full GPU processing like on a GeForce 8600 GTS (a much older card I have in another PC) ?

Anyway I'll have to revert to Catalyst 9.8 because these 9.11beta as well as 9.9/9.10 break DXVA decoding for HD video streams

That's the nature of the hybrid, it does the FFA processing on the GPU (search for repetitive pulses), but single pulses, FFTs, etc. so far have to be done on the CPU. AMD/ATI will eventually provide FFT, I'm sure, though they do not seem as interested in scientific code as nVidia. But if they want to produce video cards usable in new Apple systems they must have adequate OpenCL support, and that should provide motivation for improvement.

I am testing now.... Wu's incoming

My GPU work very seldom almost all 3 minutes for 1 minute, then pause. Have anyone an idee to get better performance ?

Have happy crunching

try to sen <count> to 0.5 instead of 1
It will allow 2 AP tasks instead of one. This should increase GPU usage.

[Skywalker66_Bln]

that is right, also all Multibeamsclients pause and both Astropulse are running with je 50% Cpu Power

for my wish, i want to run 2 Multibeams + 1 Astropule (Like Cuda) 

it works with my writing before, WU time goes longer (2. core double the time), to credits and avd.credit still too early

Set avg_ncpus to low value to allow Multibeam be running together with AP

thank you for the tip. lower under 0.10 i would not have dared, however, an attempt is worth, it will test during the next days

You can set it to 0 as long as <count> will not go lower than 0.5.
Anyway, only 2 AP from launched by BOINC will consume memory and do progress at time.

[JeffT]

Is there a readme file that explains all of the parameters?  ie.  <platform>windows_intelx86</platform>,    <count>0.01</count>
etc..

somewhere in BOINC's WiKi maybe...

Installed as specified a few days ago, but can't get any AP WU?

Yes, I have checked to receive all three types of units (seti, ap, apv5), and seti units are getting in, bot not the AP;

In messages, I get:
19.11.2009 9:57:29   SETI@home   Sending scheduler request: To fetch work.
19.11.2009 9:57:29   SETI@home   Reporting 2 completed tasks, requesting new tasks for GPU

19.11.2009 9:57:39   SETI@home   Message from server: No work is available for Astropulse v5

Any ideas? I am using Boinc 6.10.17 and ATI Catalyst 9.10.

It's really no work from astropulse available at the moment, please look at the server site of seti and you see the astropulse splitters are off... as long as they are off no work.   
We are all waiting....

The project sometimes splits work for "Astropulse v505", and that's what the app_info.xml indicates your host is prepared to handle. But the "If no work for selected applications is available, accept work from other applications?   yes" setting in the project preferences is needed for SETI main. The "Astropulse" and "Astropulse v5" settings are basically meaningless now, the first is totally gone and resends of tasks for the second are perhaps possible but highly unlikely.
