Re: Giving more than 110% -- MIDRANGE-L

When I was in LPAR class we drove a system to 1000% by running multiplecopies of SETI@HOME in PASE... The system doesn't have to be barrowingCPU from anywhere for this to happen. When configuring and LPAR with anHMC you tell the system how much CPU, say .5 of a CPU and you can thensay how many virtual processors you want. These are in .1 or 1/10th of acpu settings. So in my example here you can tell it anywhere from 1 to 5virtual processors. If you tell it 1 virtual processor yourwrkactjob/wrksyssts etc will look normal and when you have used 100% ofthat .5 cpu you gave it then it will show 100% on those screens. If youchose to assign 5 virtual processors then it would show 500% when youhave maxed out the .5 of cpu.

Why would you set more than "1'" virtual processor? Some type of workuse lots of small chunks of cpu or that have lots threads, these "may"benefit from multiple virtual processors...

That's nothing, I believe at one point our 570 was giving us 250%.

Hi Everyone,

I'm sure this has something to do with LPARs, but based on this, one
could say that iSeries give more than 110% effort when trying to finish
a job -- note the CPU% from this WRKACTJOB:
