Please explain me the relation between the cell, chip, processor, cpu and core? Those Jargons are really confusing for me even if I read lot of manuals.

P.S. This Thread has been moved from Servers --> General to HP-UX --> Virtualization - Forum Moderator

SolutionA "chip" is a chip - you need to mention the relation where this term was used.
Processor = CPU
"core" is normally used as the same term like processor or cpu. Since there are "multicore" cpus - "core" means a logical CPU inside a physical CPU module.
For example, a dual core CPU has 2 physical CPUs on a single chip - more or less.
Hope this helps!
Regards
Torsten.

By seeing the above output, Is that mean I have 4 dual-core cpu in the npar but only 1 core is active in the vpar?

Re: Relation b/w processor, core and cpu
"vparstatus -v" will give you more details about the vPar config.
Hope this helps!

Please see the o/p below:

test / > ioscan -fnkCprocessor
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
processor 0 1/120 processor CLAIMED PROCESSOR Processor
top o/p shows only 1 cpu.
From this I can able to figure out that i have 1 processor for the vpar. Is that mean I have one single core or one dual core?
Thanks,
Srini

Re: Relation b/w processor, core and cpu
This means you have 1 CPU (1 core) assigned to this vPAR.
Hope this helps!
