    Exclamation Folding & Hardware/Software Comparisons

    Hi folks, today I thought I would share some of my experiences with building a folding machine and setting them up using different configurations. This is not a guide, but merely a benchmark/comparison.

    This is the hardware I started out with to build my rig:

    - Dual Xeon X5570 2.93Ghz (3.33Ghz Turbo Boost), 8C 16T
    - 12GB DDR3 1600Mhz Triple Channel Non-ECC Cruicial Ballistix Tactical Tracer
    - 2GB nVidia GTX660 Ti SC
    - 120GB SanDisk Exrtreme SSD
    - 1TB WD Blue SATA3 HDD 7200rpm
    - 16X DVDRW
    - Corsair AX860i PSU
    - Corsair H80i Liquid Cooling x2
    - EVGA Classified SR-2 motherboard
    -- Intel 5520/ICH10R chipset
    -- 12 x 240-pin DIMM sockets (Maximum of 48GB of DDR3 1333MHz+)
    -- 1 x UltraDMA133
    -- 6 x Serial ATA 300MB/sec with support for RAID 0, 1, 5, 10 and JBOD
    -- 2 x Serial ATA 600MB/sec with support for RAID 0 and RAID 1
    -- Audio connector (Line-in, Line-out, MIC)
    -- 8 Channel High Definition (Realtek ALC889)
    -- 2 x 10/100/1000 (Marvell 88E8057)


    Currently, the CPU's are overclocked @ 3.96GHz and GPU gets a small overclock @ 1254MHz.

    So, now onto the comparisons...

    Initially, at stock speeds, fresh install of Windows 7 Ultimate, no SP, no updates, no drivers; FAHv7.3.6 installed: GPU 27K PPD SMP 40K PPD
    Then, at OC speeds, fresh install of Windows 7 Ultimate, SP1, all updates, current drivers; FAHv7.3.6 installed: GPU 27K PPD SMP 36K PPD
    Now, at OC speeds, fresh install of Kubuntu 12.04, all updates; FAHv7.3.6 installed: SMP 90K PPD (bigadv)
    Finally, at OC speeds, fresh install of Kubuntu 12.04, all updates; FAHv6.34 headless installed: SMP 144K PPD (bigadv)

    WOW! Do we see a pattern here? I sure do!

    If anyone else has their own experiences to share, please do so and post here.

    No point in reserving a post when we can only edit for a day or two... unless you plan on editing asap~

    Good info on the build. It only goes to show that Windows and GUI clients are not always performance driven. I'd hate to see the diminishing returns on my big rig if it were using Windows... I've read nearly 30% performance decrease but I don't want to test it.

    I'm moreso flabbergasted at the fact that Windows actually IS THAT bloated. I always knew system resources were being used to keep up the GUI and all its processes, but after seeing these results with my own eyes, I have really considered Linux as a long term solution. I just have to keep learning it, because I still feel the way I did when I got my IBM PS2 back in 1989, not really knowing what to do with what was in front of me.

    I have to make another set of seperate runs. I fubar'd my last Linux run for 24hrs. Got to start over but will be a few before I can. I need to roll a kernel before I do too but might not get there. The diffs shocked me because the GPU isn't running in Linux, it is in Win. I run a fairly stripped Win I leave Aero on but anything flashing, moving or fading gets killed. I'm using a cdebootstrap Debian standard x64 with MATE and my other choices added after I boot a kernel. It's real low on resources. Win is on a 120gb ssd but I put Linux on a 750gb Hybrid Seagate because I play with too many OS's at once. Linux will warp your brain. That's a good thing too. Win does something else we won't talk about. If I wasn't a gamer....
    I'll get some seperate runs down and put up the numbers. This has turned out to be more interesting than just a burn in utility.

    I only just read this thread. That is interesting, for sure.

    I run linux on everything except my desktop/folding/gaming rig. Unfortunately, because of that last part, I'm stuck with Windows. It's a shame when I think of the folding I could get out of it running linux.

    For everything else, there's Crunchbang (debian based distro) with which I am in love . Super lightweight and clean as my Caravela...

    Why not dual boot Linux and just run it when you're not gaming?

    I was thinking about it but I still use it most of the day, some gaming included. I might give it a go just for night folding and see how my PPD work out.

    I've been bench marking for about 20 years. The stability and increases of performance for ANY flavor of Linux BLOW any version of windows out of the water on every level. The only reason I have Windows 7 on any computer is for Microsoft Office, which unfortunately is required by most of my classes at my college. I boot to Windows for that and then boot back out as soon as possible. I use Fedora 18 for my servers and workstations and I dabble with Kubuntu 12.04 once in a while. Arch gives the most performance but takes considerably more effort to install.

    FYI the latest FAH Client install does not get along with Fedora 18 x64. The version of python on F18 is 2.7. FAH requires 2.6. Kubuntu 12.04 x64 runs smooth as silk.
