Is there a way to make all processes, except the ones I intentionally set otherwise with
numactl use only certain cores/memory (without looping through every thread of every process and setting it myself)?
A few more details: I have 2 physical CPU chips, each with 4 cores / 8 threads along with a total of 256 GB RAM. The memory is not evenly distributed between the two CPU memory buses. I would like the one with significantly less memory to be the general-purpose one with most programs (e.g. background tasks) running on that CPU and with its memory. Then on the CPU with most of the memory run special tasks that I will be timing the speed of and want them to not have an CPU-contention, NUMA, or anything like that.
