Hi, Thank you for all the answers. I am a newbie to this question. I usually test the processors with the top utility but on FreeBSD I can't see seperate lines for each CPU. Like on linux there there is a seperate line for each cpu and it's usage in the upper screen of top. How can I do this on FreeBSD? Should I install top from ports? Why isn't this default like in Linux systems?=20 Thx. > IIRC you dont see an explicit start for CPU #0 as its the one > running the boot sequence :) > You can use systat, top -S, ps -aux or sysctl to check for the > number of processors. look for the number of idle processes > in the first three and for either kern.smp.cpus or hw.ncpu > the sysctl. >=20 > Steve > ----- Original Message -----=20 > From: "Gannater J=E1nos" <gannater@freemail.hu> > To: <freebsd-smp@freebsd.org> > Sent: 26 May 2004 20:39 > Subject: Hyper-threading >=20 >=20 > > Hi, > > > > I installed FreeBSD 5.2.1 on my new Intel Pentium 4 based > > computer, which has Hyper-threading support. > > Although I enabled Hyper-threading in the BIOS and compiled > > the kernel with SMP and APIC_IO and it looks like it's not working. > > The dmesg says it has only one CPU and it is #1. > > In the 4.9 kernel I can see an option for Hyper-threading > > but I can't see it in the 5.2.1 release. > > What should I do to make this service work and how can I > > test it? >=20 >=20 > =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D > This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
