CPU/ATI GPU hybrid AstroPulse for Windows released

<< < (7/23) > >>

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.

benool:
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.

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

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