Hi skgiven! 1. Yeah, I only ran two tasks under Linux X64 and I know that is not representative at all. But I was fairly disappointed with the performance, that's why I tried XP instantly. I hate to contradict you, but I used both the generic drivers (later and not at the same time) and NVidia's 256.44 first, cause i knew that the Fermi has a performance boost with new drivers. I tend to look first, if there's a new driver for any of my hardware. Both were disappointing, to say the least. 2. To be honest, I'm not a Linux geek, more a Linux newbie. So I didn't figure, how to install the newest BOINC for Linux AND getting it to run. The manual to install on Linux from the BOINC website wasn't helpful at all for me. And I did have my GTX 480 running under Win 7, because I don't have any other performant NVidia-Graphics-Adapter aside from an ION, that crunched exactly a single WU, but then was too slow to report a second WU in time. 3. I hope, that this is helpful in further development; so no prob and you're welcome! Cheers, Christopher |

Hello everyone, after my FERMI GTX 480 finally seems to really having picked up the pace on XP X64 with Swan_Sync=0, I have some questions though: 1. Why is this performance not possible until now under Linux X64? Is this solely because the drivers aren't so well-crafted for Linux? Used the newest available from NVidia and the one coming from Linux itself. 2. Now under XP, BOINC suddenly reports 1345 GFlops peak, instead of 778 GFLops before. The latter can't simply be driver overhead on Win 7 X64, can it? 3. Why does a WU running XP X64 crash seriously like this one? Just thought I'd contact you as the stderr output says to do so. Annoying, as it was nearly finished... Thx and cheers, |
