Could list a 100 or 2, makes no difference since these jobs run so regular that a small sample size is sufficient to firmly and convincingly say that Linux 64 bit only needs 60% of the time of W7-64 on the same computer, alternating in dual boot. One can also say that Linux does 1.67 as much work in the same amount of time W7-64 needs to complete a target02 work unit.

The Linux box, my shiny horse, gets for the same amount of time as running on W7-64 OS, 1.7 credit more for being 67% more efficient... sigh... let me be silent again... it irks... WCG is so incredibly lucky that is all it does... the sciences is what I do it for! knreed, when will the new credit plan get out of that Seti beta track? You'll be seeing flocks return when that bar is leveled. No I'm not talking about one from the last town that Rawdy Yates visited... just make our day, and weekend :D

Yep! I've tested as you have and found Linux to be significantly faster on any project. Adjusting the points system would be a bonus.

nanoprobe, it is not true that all projects are faster on linux. I am positive that hpf2 is about the same speed, don't remember if others are the same, but they are harder to compare since the size of the WU vaires greatly.
----------------------------------------Sekerob, it would be nice if WCG upgrades the level of boinc that is downloaded from their webpage. The fact that the current level of boinc that is on WCG website does such a poor job for benchmarking on linux (40-50% less then what it should be), it just makes things worst unless you doing a zero redundancy project on linux. Because this parts annoys me the most, because this results in us getting less points per hour of work on linux when we are doing more work. Less points per WU isn't too bad, but less points per hour is just terrible.  |

No, cant say that the Linux .sh kit 6.10.17 does a bad benchmarking job (64 bit of course)... the WCG link going to the 32 bit version I think. The 64 bit is in fact so identically benchmarking versus 6.2.18 and 6.10.58 of 64 bit windows that I downgraded to the .sh version... which as I explained in that other thread why my credit still works out better overall, particularly when running quorum jobs... but that's just a sidetrack not further to be extended in in this thread, pretty please. My main drive is reconfirming that C4CW benefits hugely in speed.
----------------------------------------And yes, HPF2 is not a bit faster on Linux that I can tell. Quite diverse results with FAAH/HFCC. Almost as if HFCC runs a tad slower, FAAH definitely faster as does HCMD2 and the rocket that takes off for HCC is beyond debate... 2x faster. HFCC I did not sample sufficiently... I think testing this in depth does not add... the time lost on testing and dual booting has no payback to just make a across the board choice: Linux IS my crunching selection for the current WCG research family. Maybe armstrdj makes CEP2 run faster on Windows, but then I'd expect him to apply the same learned to a new compile for Linux, as there is a material amount of time loss on I/O, increasing as more run concurrent.

I am positive that hpf2 is about the same speed, don't remember if others are the same, but they are harder to compare since the size of the WU vaires greatly. Maybe I should have said on any project that I've tested it on. I check for WUs completed in a given period of time and not really paying attention to the varying size of the WUs. Sorry for the confusion.

Very informative post that indeed confirms what I suspected about C4CW's speed on Linux VS points awarded... One of my C2Duo machine is running Ubuntu 64-bit thru VMware on Win32 with only 2Gb of memory, to say the least, when many programs are loaded on the windows side, the machine struggles quite a bit...
----------------------------------------I'm ditching Linux and I'll run Boinc on the windoz side even if it's less efficient; I'll be getting almost the same amount of points anyway and it'll put much less strain on the machine... sight.

You know you can dual boot with windows and Linux. Run ubuntu for crunching then switch for when you need windows. Works great.

This doesn't work very well if you get a CEP2 mixed-in with all the water.   "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

Then just let the CEP2 unit finish?
