Chapter 3. Virtualization

135

Dedicated mode

In dedicated mode, physical processors are assigned as a whole to partitions. The
simultaneous multithreading feature in the processor core allows the core to
execute instructions from two or four independent software threads simultaneously. To
support this feature we use the concept of

logical processors

. The operating system (AIX,

IBM i, or Linux) sees one physical processor as two or four logical processors if the
simultaneous multithreading feature is on. It can be turned off and on dynamically while
the operating system is executing (for AIX, use the

smtctl

command; for Linux, use the

ppc64_cpu --smt

command). If simultaneous multithreading is off, each physical processor

is presented as one logical processor, and thus only one thread.

Shared dedicated mode

On processor technology-based servers, you can configure dedicated partitions
to become processor donors for idle processors that they own, allowing for the donation of
spare CPU cycles from dedicated processor partitions to a shared processor pool. The
dedicated partition maintains absolute priority for dedicated CPU cycles. Enabling this feature
can help to increase system utilization without compromising the computing power for critical
workloads in a dedicated processor.

Shared mode

In shared mode, logical partitions use virtual processors to access fractions of physical
processors. Shared partitions can define any number of virtual processors (the maximum
number is 10 times the number of processing units that are assigned to the partition). From
the POWER Hypervisor perspective, virtual processors represent dispatching objects. The
POWER Hypervisor dispatches virtual processors to physical processors according to the
partition’s processing units entitlement. One processing unit represents one physical
processor’s processing capacity. At the end of the POWER Hypervisor’s dispatch cycle
(10 ms), all partitions receive total CPU time equal to their processing unit’s entitlement. The
logical processors are defined on top of virtual processors. So, even with a virtual processor,
the concept of a logical processor exists and the number of logical processors depends
whether the simultaneous multithreading is turned on or off.

3.4.3 Multiple shared processor pools

Multiple shared processor pools (MSPPs) is a capability that is supported on
processor-based servers. This capability allows a system administrator to create a set of
micropartitions with the purpose of controlling the processor capacity that can be consumed
from the physical shared processor pool.
