I have no idea how common such scenarios are, but I could imagine that using CPU cores in a service oriented way could improve performance of some workloads. It may even be possible to have some CPU cores used for userspace only things, in a gang scheduling way. In effect scheduling a few cores together, allowing the main process (on one core) to let the other core to do some of its work during its timeslice, in a Cell like way... With 4 core CPUs becoming more common, 8 core CPUs around the corner and CPUs with even larger numbers of cores possible in the future (I do not know if they will show up), we may need new ways to effectively use all those cores. Experimenting with different ways of utilizing cores could be very useful. -- All rights reversed. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
