IT would help A LOT of you specified the OS.
pbind [processor number]

as an example. You can place this command in the user profile: ~/.profile
IF solaris is not it please specify the OS.

You cannot assign a CPU to an individual user without getting in system logical partitioning or virtualization. You can however bind a process to one or more CPUs using what is termed hard or soft processor affinity. Do a web seach for "Linux processor affinity" and you will find plenty of information about the subject.

uptime, load average, and # cpus

I was told that there is a correspondance between the number of cpus, the load averages, and when the cpus reach 100% capacity. I have 4 cpus and said that once the numbers hit 4.00, my CPUs are 100% at capacity. load average: 0.08, 0.09, 0.11 Is that correct? Thank you (7 Replies)
