KSP on VM

[Temeriki]

So I had a thought, Im not an expert on CPU virtualization, I understand the concept and can set up and use them, but I have no clue how the emulation magic works. My question is could you use 4 cores to power one virtual core. I figure you wouldnt be able to exceed the clock speed of the virtual processor faster than the onboard CPU, you would need some sort of emulation sorcery and use something to convert 32 bit virtual operations into 64bit physical operations then back into 32 bit answers (if that did work, in theory you could almost quadruple your base clock speed with 4 cores). But I dont understand how emulation sorcery works maybe someone else could throw their brain at it?

Unfortunately that is now how virtualization works. You can't make a CPU any better than what it is.

[Temeriki]

It wasnt to make it better, it was to artificially increase the clock speed using 4 cores to visualize a single core, since KSP can only utilize one core I was thinking of ways around that.

AMD was working on something like this. There was a lot of talk about their K8 chips back around 2006. The buzzword for it was 'Anti-Hyperthreading' where two or more cores would act as a single faster core.

As far as I know, nothin much came of it. Not sure if it was scrapped or simply did not provide a significant boost in performance...

*edit* Never mind, after doing some research, I now see that it was an unsubstantiated rumour...

Not you can't. No existing virtual machine hypervisor can do this, and don't expect it to come anytime soon. What you are talking about is called "automatic parallelization", which is a very hard problem in computer science.

Thank you very much, thats what I though. I do computer repair for fun, so I spent years trying to ignore the theories and science.
