Virtual folding

[ChristianVirtual]

Hello,

I'm new to folding and its quite addictive. Right now I have two boxes running: one Windows with i7-2600 and GTX660ti and one machine with a Xeon E3 1240v2, VMWare ESXi 5.1 and Ubuntu 12.4 as a folding guest. This VM has 3 cores assigned and make around 12kPPD with FahCore 0xa3. My question: is this smart or should I better use 2 cores and build a separate 1 core VM for additional folding. I need to keep a bit of CPU for other tasks on the box.

Thanks for any suggestion ...

Keep the three.

I would use as many as possible, then reduce the priority for that vm

One more question:

I recently upgraded the software form 7.2.9 to 7.3.6 on my virtual folding guest and seems I lost the capability running SMP.
I tried several times to force SMP via config file (smp v=true); but failed. The slot always went back to CPU.
Was fine the software version earlier as I could see in log files.

What would be the steps to ensure SMP comes back ?

In V7, the former uniprocessor slot and the former SMP slot have been merged into a slot called CPU. We sometimes casually refer to it as SMP, but the number of CPUs can also be set to 1 so it got a new name. Note that you have a slot that's cpu:3 that's using FahCore_a4 which has progressed to 2%.

It looks fine to me.

Thanks Bruce,

Seems I got confused by this. I read about the merger but also in 7.2.9 I still saw SMP slot in config and log files.
The above CPU:3 slot got auto detected and (unintended) auto started after removing my manual slot (which had pause-on-start). Once that slot is finished I will reapply my other options again I had in my old config.

Perhaps you were confused by the way V7 handles invalid arguments. In V7.3.6 can go to Configure + Slots and under "Add" I have two choices: I can add a CPU slot or a GPU slot. I cannot add an SMP slot. That doesn't prevent me from thinking I need a SMP slot and manually editing config.xml to define one (or from using an old version of config.xml that had one). Nevertheless, when I start FAHControl the formerly valid statements will be parsed and will be removed. Similarly, I can go to Configure + Expert and I can add an Extra_client_option saying smp=true which will do absolutely nothing, since it's now only correct if it says cpu=true. (Notice that it disappears from the listing in the log.)

If you have one concept in your mind (perhaps one that was valid in an earlier version) and the current version supports something else, there are no clear error messages explaining what you've done wrong. I might not have written the client this way, but it is the way it is.
