I had to give up on Beta. The machine had gone over 6 hours without any work. According to the Details page, it had completed over 400 MB ATI tasks without any trouble, so, I had to go where the tasks were. Seems it may have been a little chilly last night, or it's just that the Shorties run at a higher GPU load than the longer tasks. Right now it's running 2 at a time and the IO sensor reads 99F. Also, the CPU load is low when running Shorties and rises when running the longer tasks. It's now running here; SETI@home v7 tasks for computer 6796479 I suppose this will work until the APs arrive....hopefully tomorrow ;-) ID: 1609601 ·  |

Yeah I've had not any troubles either. Nice to not have idle GPU's on the Macs finally! I do wish there was a decent GPU load app for the Mac like there are on other platforms. Oh well. Thanks, Chris ID: 1609629 · |

OK, the only Windows on my Mac is the decrepit XP. I do have a recent Ubuntu though with Cat 14.9 drivers, Computer 6906726. I just ran a few with the only setting -sbs 256. I'm only getting 2 estimates in Linux, 7.5 minutes and ~20 minutes. The 20 minute ones in Linux actually finish in 20 minutes or less. The 22 minutes ones in OSX, with the same setting, are taking over 30 minutes with high CPU times. According to ATI Config in Linux the GPU load is in the Mid-90% range. Any suggestions for OSX?

That was even less helpful than the first time. Perhaps you could give some hint as to which defines I'm looking for? ID: 1610116 · |

I don't know if it is any real indication, but under application details the Mac openCL app gets between 35-40 GFLops, which is scarcely faster than the CPU scores. That's said they run much faster than the CPU by several times depending on the GPU type (my ati is about double the speed of the iGPU which is about double the speed of the CPU) that said, the fans don't even come on on either machine, which they do with astropulse. Purely qualitative without any means of measuring GPU load... Probably not overly helpful but that is what I've noticed. Chris ID: 1610223 · |

ERROR: clFFT_CreatePlan[7] failed: -46 And that concludes this round of testing. That setting Works in Windows... So far my results are, the best cmdline settings to use is NO settings. That gives the best times on VHARs, but doesn't help the longer tasks that take close to twice as long as on other platforms, and use close to 50% CPU time. So, to run the longer tasks closer to other platforms' times you need to run 2 tasks at a time. That still doesn't help the 50% CPU time, and 50% CPU time on 6 tasks will just about Kill a Quad core processor. About all you can do is hope you don't run 6 long tasks at the same time... When are the AstroPulses going to be released? Soon? Not quick enough I'm afraid. yawn. ID: 1610299 · |

Think they will ever adapt it for the NV cards in the apples? Got 2 MacBook Pro where the GPUs are sitting idle :( ID: 1629388 · |

Hmmmm.... The first link in my last post will take you to the post with the Download link. That package contains the Apps; seti_boinc-hd5xxx seti_boinc-intel seti_boinc-nv So, the nVidia version has been out for a while now. I haven't seen any reports of it being used though. ID: 1629398 · |

Installed both the NV and intel just in case. Neither has had any downloads. I've checked and made sure I've got "use Intel" and "Nvidia" check in my preferences as well as setiv7 as well as the astropulse clicked. Only thing running on the GPU is the astropulses. Took forever to get them but nothing else has downloaded. The CPU is full of work units. I'll leave it and see if anything happens over the next few days ID: 1630156 · |

Check also that MultiBeam work allowed, not only GPU types. ID: 1630197 · |

Installed both the NV and intel just in case. If you just want to test the App and see if it works you can easily set a CPU MB to run on the other device. All you have to do is change the <results> entry in the client_state.xml file to match your app_info entry for the other device. In my case I would Suspend the task, Stop BOINC and change the Suspended CPU MB task; <result>

</result>Of course Your app_info would have different entries than mine. Provided everything else is set correctly, when you start BOINC you will see the task listed as a MB GPU task. Cross your fingers and Resume the task... Good Luck ID: 1630203 · |
