Data Object
Description
This data object type describes the CpuSchedulerSystem configuration
for optimizing hyperthreading. The primary hyperthreading
optimization employed by the CpuSchedulerSystem is to utilize
hyperthreads as additional schedulable resources. Although
hyperthreads provide limited additional concurrency,
certain workloads (such as idling) can take advantage of
these hyperthreads. This is particularly useful for SMP virtual
machines that use gang scheduling. (Gang scheduling refers to a
situation in which all of a parallel program's tasks are grouped
into a "gang" and concurrently scheduled on distinct
processors of a parallel computer system.)
Changes to the hyperthreading optimization can take effect only
after a system restart. Therefore, while it is possible to change
the configuration at any time, the change will take effect only
on the next boot.

Description
|
| active | xsd:boolean |
The flag to indicate whether or not the CPU scheduler is
currently treating
hyperthreads as schedulable resources. Setting this property
involves a successful invocation of either the
enableHyperThreading() method ("true") or the
disableHyperthreading() method
("false"). The property is set once the system is rebooted.
|
| available | xsd:boolean |
The flag to indicate whether or not hyperthreading
optimization is available on the system. This property
is set by VMware prior to installation.
|
| config | xsd:boolean |
The flag to indicate whether or not the CPU scheduler
should treat hyperthreads as
schedulable resources the next time the CPU scheduler starts.
