I forgot to mention it, but another complexity is that thread to CPU affinity configuration is also OS-specific. Several systems appear to support pthread_setaffinity_np(3) but it's an unofficial extension (hence the _np suffix). The interface to manipulate cpuset_t also appears to vary (I have cpuset(3) on NetBSD and cpuset(7) on Linux, and they differ). -- Matt ------------------------------------------------------------------------------ Everyone hates slow websites.
