I distinctly remember playing with BeOS on a dual processor system.
They had an option to shut down (more likely simply fail to use) either
processor. There was a button you could click and watch your load
jump to the remaining processor and the clicked one fall to zero.

I never found a valid use for this but it was cool to watch.

man taskset

I learn something new every day. I know how to do this in C code. Never
knew there was a command line tool.

What I am trying to determine is, when I leave the kernel to its own
devices, is it running my 2-thread app so that one thread runs in one
core and the other in another. Both threads do lots of basically
independent work on shared buffers. Is there a tool to see which cpu a
thread is running in? I can't seem to see the threads in ps or top. Some
brilliant tool is surely just waiting to tell all. Right?
