thanks for your replies, of all solutions offered, it looks like isolcpus
gets me the closest.
I read up on isolcpus and it seems like it will partition off cores away
from automatic spawing of userland threads, which is...close enough to what
i want. i did read, however that kworker threads will continue to spawn
across all cores. this makes me wonder how it might work in my case
if java instances are running on 4 cores, and kworkers can spawn anywhere,
isnt all the work being done in java eventually going to end up in a
kworker..and therefore just running anywhere?
maybe ill just have to do some testing and see what happens
