prmmonitor on multiple CPU system

[Mark van Hassel]

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. See below the output of prmmonitor and top:

The CPUs are fully loaded and the tests worked fine on a single CPU system.

What could be the problem ?

Remark: when I start one proces on a SP system it consumes 100% CPU, when I start 4 on the 4 way system they consume 400% CPU. So in my opinion it is a good test to start 8 processes as different users.

This has nothing to do with your posting but I thought that your name sounded familiar. I work for AtosOrigin in the US.

Hi Dustin,

You're right, I work for Atos Origin in the Netherlands. By the way, the PRM test is on one of the CLASS systems. :)
