topic prmmonitor on multiple CPU system in Operating System - HP-UX https://community.hpe.com/t5/operating-system-hp-ux/prmmonitor-on-multiple-cpu-system/m-p/2677265#M907221 As a PRM test for 8 users I run a little CPU stress program (just an infinite while loop)on a four-way system. When I check with prmmonitor, the percentages do not seem to be OK. I run PRM C.02.00 on HPUX 11.00.

So in my opinion it is a good test to start 8 processes as different users.<BR /><BR />Mark Wed, 06 Mar 2002 17:14:02 GMT https://community.hpe.com/t5/operating-system-hp-ux/prmmonitor-on-multiple-cpu-system/m-p/2677266#M907222 Mark van Hassel 2002-03-06T17:14:02Z Re: prmmonitor on multiple CPU system https://community.hpe.com/t5/operating-system-hp-ux/prmmonitor-on-multiple-cpu-system/m-p/2677267#M907223 This has nothing to do with your posting but I thought that your name sounded familiar.

By the way, the PRM test is on one of the CLASS systems. :)<BR /><BR />Mark Thu, 07 Mar 2002 07:11:39 GMT https://community.hpe.com/t5/operating-system-hp-ux/prmmonitor-on-multiple-cpu-system/m-p/2677268#M907224 Mark van Hassel 2002-03-07T07:11:39Z
