cpu 0 : socket 0, [core 0], hyperthread 0 cpu 1 : socket 0, [core 0], hyperthread 1 cpu 2 : socket 1, [core 0], hyperthread 0cpu 3 : socket 1, [core 0], hyperthread 1It's sensible to reserve cpu 0 for domain 0, and then put all your other domains on CPUs 1 and 3 (leave CPU 2 empty, unless you know that you're not going to thrash the chip's cache). How can I know if I'm trashing the chip cache? -- Med venlig hilsen / Best regards Lars E. D.
