Intel P4 Hyper-Threading Question


Machine: P4 (Prescott) @ 2.8 GHz, 1024MB RAM (PC3200, dual channel).
Linux: Fedora Core 4

How can I know whether linux is taking advantage of my processor's hyper-thread? Do I need to do anything special to get Linux for use Hyper-Threading?

Also, on another machine (a dual P3) how can I know if Linux is using both processors - do I need to install anything special?

Thanks in advanced.

try running "uname -a"
it will display your kernel and version, as well as afew other things.
your kernel should have 'smp' in the name (symmetric multiprocessing); i believe this is basically reassuring you that it is using the HT/dual processor technology.

less /proc/cpuinfo
Search these fora for cpuinfo if you need explanation.

Actually if the kernel is compiled for hyperthreading AND the proper processor type is selected (not generic x86) then you should look for both "smp" and "ht"
