No switching needed... VirtualBox http://u8untu.blogetery.com/2010/11/06/create-a-windows-virtualbox-session/ or Wine https://help.ubuntu.com/community/Wine allows for running a Windows session inside Linux. Saw that brinktastee already has a Wine session running with BOINCTasks inside. He may pretty plz write up the instructions for the interested (me for instance), how to install Wine and how to add BOINCTasks as an application :P
----------------------------------------edit: For the Inglesides on this planet, of course one can also run under Windows a Linux session in a virtual machine. Think to have seen at least one free and easy solution allowing the Windows dependent to stay in Windows and crunch under Linux for those sciences that run majorly faster on that platform.

Then just let the CEP2 unit finish? Finishing a task can take many hours, so wouldn't really be an option if you needs to use windows now. Also, due to CEP2 often using 1+ hours between checkpoints, just shutting-down now is neither a very good option... As for Wine and other similar tools, there's still many programs Wine can't handle satisfactory, so isn't a replacement for re-booting to Windows.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

Egad, I just got to see the points discrepancy first hand. I'd done all my crunching entirely on Linux since joining up this past Jan. Now my husband bought himself a Windows laptop and is letting me crunch on it when he isn't using it. So I decided to try it first on C4CW so I could compare its performance directly to my Linux boxes. Yup, the core I3 Windows laptop takes over twice as long to run a C4CW target 02 as my Core 2 Duo Linux laptop, and gets 1.5 times as many points for the same amount of actual computation. That hurts. Why on earth does BOINC systematically reward inefficient crunching?
----------------------------------------My Ubuntu laptop gets 25-30 points per hour of CPU time with CEP2, compared to about 20 with C4CW. So either CEP2 awards points more fairly to the two operating systems, or else Windows folks really get a jackpot with CEP2. Has anyone been able to compare Linux and Windows timings and performance on CEP2? (I can't run CEP2 on hubby's Windows machine because he needs to be able to shut it down whenever he wants, and I don't want to lose hours of CPU time due to infrequent checkpointing.) And it would be hard to make a fair comparison of CEP2, since its WUs aren't consistent like C4CW.  |

Are you comparing a laptop to a desktop or are both laptops? CEP2 is brutal on any computer and I wouldn't run that on a laptop. Very heavy work on the hard drive. Windows OS runs allot of processes running whereas Linux has less. Linux is more lean OS. I ran clean water on a 8 core w/hyper threading (16 threads). Completed 80 on win7 64 bit. Ubuntu 64 bit completed 112. Would never go back to windows. It does seem the slower systems get allot of points vs faster on CEP2. Not sure why.

Yes, I am currently running CEP2 on my Linux laptop. It's a Core 2 Duo with no hyperthreading, so just 2 jobs at a time. Thus the hard drive beating isn't what it would be with 4 or 8. Even so, I probably won't keep running CEP2 on it once I get to Ruby (which should happen in a couple of days).
----------------------------------------Then I'm planning to build a desktop over Christmas, purely for crunching. It will become my main CEP2 computer. I really want to do my share in that science! The new machine will run under Ubuntu -- my favorite OS, and efficient for crunching. Darn those points! |

Points will come with time crunching. Hope your building your new computer with newer processors. More efficient and use less electricity. The westmere chips run pretty cool compared to my harpertown processors. Happy crunching!

Well well, by the looks of it, this thread should be dead very soon! Currently testing new Windows Betas and my oh my, they are FAST! Even faster than the Linux64 platform: here's a sample:
----------------------------------------Linux64: 1.9 hours Win764: 3 hours WinBeta: 1.7 hours I'm impressed!  |

yeap, it seems that the new version of c4cw (currently in beta) is 5-10% faster then linux.

Good to hear that there is some optimization going on, and that those of us with slower computers can make a more meaningful contribution to the science.
