[opensuse] Some questions about performance evaluation.
Dear all, Could I make one or more processes run only on certain CPU(s)? And thread? Could I make some of the memory disappear from most of the kernel and user space? So I can evaluate performance on a smaller memory without removing them physically. Thanks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

First question is probably about multiprocessor systems. I know that it is possible to use maxcpus=0 to make system use only one CPU, maxcpus=1 will use 2 of them, etc. mem=128M will use only 128 MB from whatever is installed. BTW, a little of Google may help you faster. -- Regards, Rajko. http://en.opensuse.org/Portal -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

man taskset
And thread? Any thread started by a taskset process will share its processor affinity.

Perhaps use a ramdisk? http://www.vanemery.com/Linux/Ramdisk/ramdisk.html -- _____________________________________ John Andersen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
