Linux & Windows, how do i automatically set tasks to a numa node?

ok, so here's the deal. 

 

i would like to set specific applications like games to 1 numa node (1 cpu) and run all of my other crap on the other cpu. how can i do this?

 

i want to do this in both Ubuntu and Windows 8.1.

 

the reason is if i have a bunch of stuff running i can feel slowdown in games, and i can see a lot of activity on one node where the other one is almost unused. 

 

i would also like to pin games to one specific node, the one that my gpu is connected to.

I know on Windows is possible by using task manager and set the processor affinity to a single core, or just using CPUCORES (maybe better since not all games like the task manager)

 

On Linux I've heard of numactl but never used it, it's scheduling is far more decent
