We've got around ~15 relatively decent Windows machines in the office and I'm wondering if it's possible to set up a system that clusters them as a single virtual machine when they're not in use during office hours.
We run a lot of CPU intensive numerical simulations and rather than buying standalone simulation machines, it'd be nice to leverage the unused office workstations at night/over the weekend (ideally as a single VM with many CPUs).
If this is possible, where would one start looking to go about this? Are there any common issues/considerations I should be aware of?
Thanks.
