Has anyone noticed if the Rosetta application favors AMD or Intel (or even PowerPC)? I know with some other BOINC projects, one type seems to be preferable, whether the cause is specific optimizations or cache size, etc. Thanks... |

as far as i red until now, the time per unit varies a lot, so i guess it is to early to compare cpu times. with only one wu per computer, my intel xeon 2.4ghz cpu seems to be faster than my 4400+ amd but as said above, it does not say too much as 1 unit per host is far to less to tell some average. -- Florian www.domplatz1.de |

FZB is right, the actual completion times do jump around from work unit to work unit. The standard deviation is too large to make a comparison meaningful at this point. There's even talk of pending optimizations to the application, so it's just too early to tell. |

In the mean time, you can do what I am doing. Get one work unit, process it with No New Work for the project. Get another work unit by unsetting that and then Update the project. That way, you don't get too much work while in testing. This may not work as well when 4.72 gets the processsing time down to a reasonable number (Mine is at 240 hours when real time is more like 2-4). |

I'm not sure if I'm just lucky or what, but even from the first, the estimates were fairly close, and continue to tighten up. Estimated times right now show about 5 1/4 hours, with actuals being 4 to 4 1/2 per WU. |

Initially, with the original apps. My iMac G5 was almost twice as fast as my windows machines. The optimized Windows app changed all that though, so Windows is several times faster. Don't know yet if any optimizations were added to the Mac app 4.76 or not, still have several 4.75 work units to complete. It would be nice if all the OS's had optimized apps, but that may take some time. I like this project though, even in beta. Team MacNN - The best Macintosh team ever. |
