Sure - that works great. (Theoretically you could do this all in userspace - start by assigning "guarantee" nodes to a container/cpuset and when it gets close to its memory limit assign more nodes to it. But in practice userspace can't keep up with rapid memory allocators. > > BTW, can you do these with fake nodes: > - dynamic creation > - dynamic removal > - dynamic change of size The current fake numa support requires you to choose your node layout at boot time - I've been working with 64 fake nodes of 128M each, which gives a reasonable granularity for dividing a machine between multiple different sized jobs. > > Also, How could we account when a process moves from one node to > another ? If you want to do that (the systems I'm working on don't really) you could probably do it with the migrate_pages() syscall. It might not be that efficient though.
