I am working right now on an "Official" diskless VMWare image that will use a .vmdk virtual disk to run from and save and restore the WUs, keep your eyes open for the next release.


That sounds like the perfect solution :)

Linux SMP or WinSMP? And what's your secret ;)

@notfred good news to hear about .vmdk virtual disk. I briefly tried to set one up and kept getting host/guest driver compatibility errors.

@cob no secrets... A lot of reading, 2 weeks of trial and error, quality components (RAM gets finicky @ 1200MHz), and having a motherboard that allows tRD adjustments is a requirement. Luck also plays a role, WU assignment can very PPD over 2000 :) The box I'm talking about is running notfred's 1 SMP/2cores (2 SMP Clients on a Q6600) In general however higher PPD is easier to obtain running 2 SMP clients under VMWare Server (tends to get a better WU mix) It was really a fluke that I got this machine running so fast I was trying to build a energy efficient box but it was running so well I just kept cranking it up. It still does quite well on a PP/Watt basis as it runs about 150W under full load. I don't know if this plays factor in performance (maybe from a stable power perspective or non restricted airflow) but this box has NO HD, NO CD, NO Video...Just RAM, CPU, HSF, and USB stick.

Ah well that's explains a lot ;) Vista and VMWare like to steal a few resources on my system :lol:

I've mentioned the diskless method to a few of the members running dedicated crunchers on my team. It's a superb idea and something I'll be keeping a very close eye on :)

Hi guys,

I'm getting the following problem whilst trying to set this up on a VMWare Server. The USB drive I have is being detected correctly, and I've downloaded the iso a couple of times just in case it was something I did....

Any ideas? :)

It's because I was half way through doing a VMWare appliance (save and restore from a virtual disk - /dev/hda1) when Stanford switched the URL and I had to release early. Don't worry about the message, it's just saying that it can't find the VMWare virtual disk.

Ah ok, thanks :) I look forward to the release where you can save to a virtual disk then :)

Would this also be the reason why FahMon claims that the diskless instance is *Hung*?

Thanks for a great program.

FahMon has trouble monitoring VM clients. If you have a windows box FahSpy does much better monitoring clients running in VM's.

Cool thanks :) I didn't know this one existed so I'll try it out tonight.

Well I finally got around to running this tonight on an E6600. And, as was to be expected, the single SMP client allocated to the E6600's two cores was only using ~90% of the CPU. So with a little edit of the fold.iso it was simple enough to persuade it to download and run two SMP clients, thus maxing out the CPU

Frame times will ofcourse be ~90% longer than they would be with a single client, but the ppd should be a good 10% higher. And every little counts :lol:


Thank-you for an awesome application :)

You'll know this by now, but I'll pop the solution up anyway.

Ticking the 'Ignore asynchronous clocks' option in Fahmons options solves the 'hung' message.

Hi

2 machines are running the USB stick version fine (love it by the way!)
I'm trying on a 3rd machine but it just keeps rebooting after the trying to start core part....overclock is minimal and was folding in windows just before trying this.
This one however is a 4gb usb flash drive ,the others were 2gb,all same brand though.

I have three boxes all hard wired into a linksys wet54g ethernet bridge which is getting our internet wireless from upstairs.


I tried formatting it again using HPUSBFW utility as FAT (not NTFS or FAT32) then unzipped the files directly to the usb stick
Then I go Start>Run>CMD and type syslinux D: and it copies onto the USB drive a file called ldlinux (system file)

I then unplug and put it in and boot to it.

Its here where this PC goes into an endless loop of rebooting after the trying to strat core part.
