Just as a data point, I have run dual-processor systems on both 3.0-beta (pre-release) and 3.2-release. On both, I definitely see "CPU0" and "CPU1" show up as state's in 'top -SI' on the same screen-update (and sometimes a few more processes in READY...). Those are separate processes, not separate threads in one process. If you don't see multiple processors active while you're running multiple cpu-bound processes, then I doubt an upgrade to 4.0 will whatever problem you're seeing with 3.3-release... (unless maybe you do have some config wrong and you happen to correct that while installing the new release). What do you get for output from: dmesg | grep -i cpu If you're trying to run multiple threads in a single process, well, other messages have already given the details of the current status of threads. --- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or drosih@rpi.edu Rensselaer Polytechnic Institute To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
