Quelque chose comme ça
http://www.tech9.net/rml/schedutils/
schedutils currently contains the following programs:
* chrt - manipulate real-time policy and priority of tasks
* taskset - manipulate task CPU affinitytaskset is used to set or retrieve the CPU affinity of a running pro-
cess given its PID or to launch a new COMMAND with a given CPU affin-
ity. CPU affinity is a scheduler property that "bonds" a process to a
given set of CPUs on the system. The Linux scheduler will honor the
given CPU affinity and the process will not run on any other CPUs.
Note that the Linux scheduler also supports natural CPU affinity: the
scheduler attempts to keep processes on the same CPU as long as practi-
cal for performance reasons. Therefore, forcing a specific CPU affin-
ity is useful only in certain applications.
Maintenant, il est aussi possible d'assigner le traitement de certains IRQ a certains processeurs
