I have done this, and I am currently re-writing it from scratch, for 2.2 http://isunix.it.ilstu.edu/~thockin/pset/ is the URL for the old code...it is currently undergoing a complete from-scratch rewrite, with new features.
Features do/will include: new system call sysmp (compatible with SGI) library wrappers for bind_to_cpu() (digital UNIX) library wrappers for processor_bind() (Sun? - who uses this?) Restrict processors from running general processes lock a process to a processor, or set of processors remove a processor from general use, and lock it to a single process (and it's children) disable a processor from scheduling any processes
does this sound like what you want ?
