high system cpu utilization on single processor of mutiprocessor system

[Jason Mackanick]

I have a K-class that has one processor with a high system cpu utilization time. The other three are almost idle. Top does not show this, but glance does. I don't see any processes with high utilzation either. Any suggestions?

Tere is no way other than by pushing processes of cpus or using wlm to specify where the load goes.

The problem is probaby due to many single threaded apps all running.


See here for a prog to assign a process to a particular cpu.

I have always found 'top' to be pretty accurate. Could you post its output?

The process (default) or 'g' screen in glance can be configured to filter out processes. Could this have been done so that you are not seeing a process that's using a lot of cpu?

[Jason Mackanick]

Top is not showing anything high and it does not show the processor having a high system utilization like glance plus does. I am unable to post the output of top due to the fact this server is not connected to the internet.

Assuming your AP's have not gone berzerk with processor affinity at the app level, you will find that non-threaded applications will usually "stick" to one CPU. There are even cases were the right combination of apps will hammer the snot out of the monarch CPU (usually CPU 0 -- determined at system boot).

Please post a top screen and a glance "g" screen. We'll try to help you out!
