CPU Utilization

Tham, Huei Hwan — Fri, 22 Dec 2000 06:34:19 GMT

Hi all,

I need some explanation on how HP 9000 (HP-UX 10.20 / 11.00) allocate CPU resources. Is there any UNIX command can find out what are the processes runing on top the physical processor on the multiprocessors system ?

Basically, on which processor HP-UX will run most of its systems process (ie. swapping, interrupt and so on)

Hi there.
Try the top command. It will show the load on each CPU and the CPU with the largest load and
the process#, which causes the load.

Try with the command top.
If in the system has been activated PerfView you can use "glance"and its graphical version "gpm"

Download and install lsof from HPUX porting site: http://gatekeep.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.51/. You can read the online manual for more information.
Also using Glance will be of help and a combination of ps -ef, top, sar, etc.

Hi:

My preference is Glance as a runtime tool. For some good white papers on multiprocessing and process management, see:
