I'm going to be updating the backup scripts some time shortly, any feature requests?  I was planning on adding an additional file that lets you know which hour is the latest backup since that can be a bit confusing with the client running on a different timezone than most people are on.

You might want to hold off on that. Stanford had stopped the Linux -bigadv for now.

I think it might be beneficial to have the script backup when the folding client is not writing a checkpoint. One of the things I was playing with was checking the timestamp of the last written checkpoint. I took the difference between the current Unix timestamp and the last written checkpoint Unix timestamp to get an idea if it was time for a new checkpoint to be written and if so, wait a few minutes before proceeding. The default checkpoint time is every 15-minutes. I can post the code for what I have so far for checking the timestamp if you think it would be useful.

Ya that was something I was trying to figure out how to do and never managed to think of a way to do that.  I'm not sure if it's possible to delay a cron job but if I used a script with delays built in then this should be doable .... I think :)  No hurry for the code since the Linux bigadv WUs have stopped but when they start up again I'll take a gander at your code.

You´ll get better ppd from the win smp client, due to not having the overhead of the vm player.
And now wtih the new exe install is much easier as you can skip the part with the install.bat and windows login

Well now I may go ahead and set this up on the second rig as its my dedicated folder.  I haven't worked with Linux in a while though, so I maybe coming back to ask some questions I may have.

Thanks for updating and providing such a great detailed guilde!

If the rig is going to be dedicated for CPU only, you could also try my native Linux image which will give better performance than a VM in Windows. The CD ISO has a raw image built into it for writing to a hard disk. Just make sure to hook up the correct hard drive to the board for overwriting with the image and only hook up the one disk. This image has the same web configuration as the other images.

For GPU folding, you probably want to stick with Windows for the host OS. You could run the virtual machine using my image in Windows for the CPU bigadv part. I get better numbers with Linux in VM than via native Windows. However, the GPUs will affect that some so you might might want to experiment to see which CPU configuration gives you the best performance. I built these images primarily to get maximum performance out of bigadv.

hi linuxrouter,

Where do i get linux image for Virtualbox? I have windows with 16cores that I want to try out to see if TPF improves.
I tried Linux VMWare on couple machine (all i7s) they work fine, except one machine got crash (only have 3GB on that system). What would be the minimum RAM for linux vmware when folding -bigadv at -smp 8.

thanks
