Hello janit0r,
Unfortunately, I'm seeing more like 15-25% performance for the faah processes ?? How do you measure performance on an Intel Mac? I am surprised by your low figures, though I do not have a system to cross-check on. Lawrence |

How do you measure performance [between emulated and native] on an Intel Mac? I have no specific utility for metrics, I just compared BOINC's progress and completion on the same Intel MacBook Pro 2GHz for: - emulated projects: BOINC for Mac on OS X - native projects: BOINC for Windows via Parallels Desktop on OS X - native projects: BOINC for Windows via BootCamp Hardly scientific as I didn't isolate the machine or spend months crunching and average the results, but it was enough to satisfy. It's disappointing that I can crunch faster on one core "natively" with Parallels Desktop than I can with BOINC for OS X running on both cores, but operating that way or leaving this machine running Windows is unacceptable. I like BOINC and WCG though, so I'll resume contributing after the project files are universal. |

janit0r, that can't possibly give you meaningful results. Even within the same project, work unit times can vary enormously. Between different projects, there is no basis for comparison at all. CPN has year-long work units, some projects have work units that take ten minutes.
WCG work units are designed to take an average of ten hours on an average computer, but work units that take a whole week are not unknown. If I had access to an Intel Mac I would try to get some hard figures for you, but I don't. I'll ask WCG on your behalf for some figures, though. |

Hello janit0r,
----------------------------------------That sounds like a fairly reasonable sort of comparison. My Sempron 3100+ BOINC Windows system has been running FAAH for this last week with results taking from 5.64 to 6.99 hours - - very consistent. What sort of timings did you get? Lawrence Added: Unlike Didactylos, I am assuming that you were running FAAH in all 3 environments. [Edit 1 times, last edit by Former Member at Aug 2, 2006 7:08:10 PM] |

I'm not risking going on assumptions. I've asked for some definitive data.

... and now I have the information.
Emulated is about three times slower on average. So it's worse than I hoped, but better than you thought. Fortunately, this won't be an issue for very long. Keep an eye on the forums, and soon native crunching will be available for Intel Mac users everywhere. |

I just got my g/f to sign up for WCG the other day. Her laptop is a new intel-mac i think 2.0 GHz dual core. From this thread, am I understanding correctly that WCG is not running properly on intel-macs? Or is it that WCG does not run correctly so it needs to be done through BOINC WCG? Or am I just totally confused? Any help? Thanks!

Please see this news: New application versions on BOINC. Releasing ...e and Help Defeat Cancer.
----------------------------------------Also if you/she plans to run McAfee, get the BOINC version 5.4.11 as it resolves communication problems between the BOINCmanager and the science programs (FAAH/HDC/HPF2). The previous recommended version was BOINC 5.4.9. cheers

Keep an eye on the forums, and soon native crunching will be available for Intel Mac users everywhere. Since I gave Didactylos that info I will have to correct it. Based upon the intel-mac results being returned so far, the workunits are running in about 1/8th the time they were taking previously (in other words they are now running 8 times faster then they were when the were running under emulation). The computers we did testing on ran in 1/3 the time but the gain could vary by processor or memory. |

I do hope it's occurred to someone that the low number of Intel Macs on the grid is partially due to the lack of native agents. I can't be the only one that's just not going to bother running under Rosetta. I look forward to many more intel macs signing up! We now have intel-mac binaries available for FightAIDS@Home and Help Defeat Cancer. |
