Since I saw that a WU on Ubuntu 64 is almost twice as fast than on Win 7 64, and also a WU on Win 32 is slower than on Win 64, it gave me an ideea.
----------------------------------------Although the VM are a good solutions for running faster WUs on different OS, I'm thinking of using collaborative linux like andlinux or pubuntu, to see if they have some advantages over virtualbox with ubuntu. I hope I can do this soon, but if there is someone who is getting bored and understood what I said above, please post the results here. Currently, I have only 64 bit machines, but maybe I can test this on a 32 bit. |

Hi cristipurdel,
For years I have been considering getting Acronis Disk Director ( http://www.acronis.com/homecomputing/products/diskdirector/ ) so I could boot into Windows or Linux as I chose. No speed compromise. Now that I am running Windows 7 64-bit Professional and am disgusted with the Windows XP 32-bit emulation mode which is almost useless (in my opinion), I intend to finally get it so that I can install Windows XP 32-bit on this computer and run my legacy Windows and DOS programs. No speed compromise and no weird interactions with Windows 7 64-bit Pro.  Lawrence |

Or you could use virtualbox to run win xp, and copy paste the whole image to make the back-up to your system ;)

We have seen a dramatic improvement of Windows performance recently in C4CW. Any indication when the same thing may happen in HCC as well?

The techs through uplinger indicated, right at the start of the C4CW beta, that all sciences that have a considerable performance differential will be revisited... so consider it WIP. The impact for HCC would be dramatic, even if only half were achieved.
----------------------------------------edit: Took a while to find the post: We are working towards making changes for the other science applications where there is a runtime difference between Linux and Windows. Also, the beta work units were sent out with Zero Redundancy so there should only be a few more stragglers of work units returning. -Uplinger [Dec 17, 2010 4:53:50 PM] [Edit 1 times, last edit by Former Member at Jan 15, 2011 10:24:10 AM] |

Lawrence, I think you can just install Ubuntu on your existing system; it is capable of creating a seperate partition within the existing drive and I think it allows you to select which operating system to boot to. Perhaps someone can confirm this?
You can certainly install XP, W7 and other Windows operating systems on different partitions on the one drive, and mulit-boot during start up. |

I can't help wondering, if equivalent work went into speeding up the Linux work units that is going into the Windows units, just how fast would they be?
----------------------------------------I also wonder what would be gained by going 64bit, given the improvements we're seeing with C4CW now.  Currently being moderated under false pretences |

I'm curious: are Linux machines penalized in points for faster crunching in HCC, as they used to be with C4CW? I just went back to crunching HCC recently, and am kind of startled by the very small points per hour from HCC on my Linux boxes compared to what these machines get on other sciences. Or are my machines just bad at HCC?

Yes. They get penalised. When a machine running 64bit Linux can do what are supposed to be the same work units in half the time but gets less overall credit by a margin than an equivalent (hardware wise) Windows machine it's pretty obvious there's either a penalty against Linux or a bonus being credited to Windows.
