Hi Guys, On CPU's, does Red Hat count duel core as 1 CPU or 2 and what about Quad's?

I thought there was something like that. I'll try that first, then get physical if it doesn't work. Thanks, Mike. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Barry Brimer Sent: Tuesday, April 10, 2007 3:47 PM To: General Red Hat Linux discussion list Subject: Re: Restricting number of CPUs Quoting "Young, Mike" <Mike.Young@xxxxxxxxxxxxxx>: > Hello, > > We have 4 CPUs installed in a server, but would like to limit it to only 2, > since an application is priced per CPU.

To limit the entire system to a certain number of CPUs, add "maxcpus=X" to your kernel line in your grub.conf (without the quotes) and replace "X" with the number of CPUs you want the kernel to see. <http://kbase.redhat.com/faq/FAQ_80_602.shtm> To limit an application to a certain number of CPUs, use the taskset program included in RHEL. <http://kbase.redhat.com/faq/FAQ_43_3918.shtm> HTH, Barry -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
