I am getting a message that no usable GPU found. Is there going to be an upgrade so that Mac ATI GPUs can crunch? Thanks Kenn What is left unsaid is neither heard, nor heeded. Ce qui est laissé inexprimé ni n'est entendu, ni est observé. |

Eventually, they are still working on getting ATI support for the time being. And similarly so for Linux. Except... I thought s@h didn't have any ATI GPU support so far... ;-) Happy crunchin', Martin See new freedom: Mageia Linux Take a look for yourself: Linux Format The Future is what We all make IT (GPLv3) |

... We can crunch Astropulse with the hybrid app in Windows. Now that's interesting. I'll have to have a look on Lunatics again. e@h have a cuda app for their Arecibo data pulsar (pulses) search (PALFA). They gain a speedup over that of using the CPU only, but not much. The GPU is left idle for the majority of the time. Any CUDA hacking for the s@h astropulse or would it too suffer low GPU utilisation?

Collatz and Milkyway are the only 2 projects that use straight up ATi gpu's and if you choose one of them just know that the MW WU's tend to run your GPU harder than the Collatz. My 4770 runs at around 50C on collatz and 56-57C for MW. the MW WU's are very short for a newer ati(1 minute for 50+ credits) and collatz runs in less than 20 minutes for 700 credits. IF you are using a CPU on these WU's they will take hours to run In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Collatz and Milkyway are the only 2 projects that use straight up ATi gpu's MW WUs are now ~4X longer, as of today. They are taking between 4 and 5 minutes on my 4850 and pay 213 credits. Calm Chaos Forum...Join Calm Chaos Now |
