Since I'm not doing much other than the folding within the VM, all I need for resources dedicated to it are those directly related to the folding.
I don't suppose anybody has already done the legwork on this have they??? :)
with the current wu's, having a vm larger than ~440 MB is wasteful once the client is running. You might be able to run with less but it was good enuf for me since they are dedicated rigs. I could increase it's refresh frequency to more that 10 minutes which i use now but like 10 minutes ... the default is 5 minutes.
Having more than that makes the ui to the guest linux more responsive, and gets the vm and smp client started faster. Since i seldom touch the linux ui or client once it is folding, on my 1 gb quads i make each vm 440 MB and set the host memory to 880 (default is 896 on a 1 gb rig).
The largest wu's when i last looked (ie in native linux via system monitor) took around 400 MB total, so 440 is reasonably safe i think.
This is one reason for not running fahmon in the linux guest .... run 1 copy on wxp to monitor all your vms. Fahmon can be a bit of a pig on my wxp monitoring rig but probably because it is monitoring 27 instances and reports network share errors regularly.
