CPU workload

CPU workload

Hi,

I'm running 2 machines on a rp7405, everything is split evenly. The thing is, machine A works much more than machine B at specific times. I'd like to allocate one of the 2 cpu's of machine B to machine A for, lets say, a 4 hour block everyday. Can anyone tell me where to start or where to find the appropriate documentation? Thanks.

Re: CPU workload

Are they hardware or virtual?

Hardware - you can't - cause cpu's have to be part of single partition only.

Virtual?

Re: CPU workload

I assume that you are using Virtual Partitions. In that case, I would be tempted to tell you that you can use a cron job for the scheduling of your moves, and that you have to look into Unbound CPUs for your CPU that will float from one machine to the other one.

You can find more info at HP Docs web site :

But you'll have to make sure that
1) Your machine were set up with unbound CPUs
2) Your min/max CPU # on each vpar can accept the additional CPUs
3) You'll need to set up a small script/command in cron to do the vparmodify
Cooperation is doing with a smile what you have to do anyhow.
