Constructor Details

LogicalProcessor

public LogicalProcessor(int processorNumber,
 int physicalProcessorNumber,
 int physicalPackageNumber)

Parameters:

processorNumber - the Processor number

physicalProcessorNumber - the core number

physicalPackageNumber - the package/socket number

LogicalProcessor

public LogicalProcessor(int processorNumber,
 int physicalProcessorNumber,
 int physicalPackageNumber,
 int numaNode)

Parameters:

processorNumber - the Processor number

physicalProcessorNumber - the core number

physicalPackageNumber - the package/socket number

numaNode - the NUMA node number

LogicalProcessor

public LogicalProcessor(int processorNumber,
 int physicalProcessorNumber,
 int physicalPackageNumber,
 int numaNode,
 int processorGroup)

Parameters:

processorNumber - the Processor number

physicalProcessorNumber - the core number

physicalPackageNumber - the package/socket number

numaNode - the NUMA node number

processorGroup - the Processor Group number

Method Details

getProcessorNumber

public int getProcessorNumber()

The Logical Processor number as seen by the Operating System. Used for assigning process affinity and reporting CPU usage and other statistics.

Returns:

the processorNumber

getPhysicalProcessorNumber

public int getPhysicalProcessorNumber()

The physical processor (core) id number assigned to this logical processor. Hyperthreaded logical processors which share the same physical processor will have the same number.

Returns:

the physicalProcessorNumber

getPhysicalPackageNumber

public int getPhysicalPackageNumber()

The physical package (socket) id number assigned to this logical processor. Multicore CPU packages may have multiple physical processors which share the same number.

Returns:

the physicalPackageNumber

getNumaNode

public int getNumaNode()

The NUMA node. If the operating system supports Non-Uniform Memory Access this identifies the node number. Set to 0 if the operating system does not support NUMA. Not supported on macOS or FreeBSD.

Returns:

the NUMA Node number

getProcessorGroup

public int getProcessorGroup()

The Processor Group. Only applies to Windows systems with more than 64 logical processors. Set to 0 for other operating systems or Windows systems with 64 or fewer logical processors.

Returns:

the processorGroup

toString

public String toString()

Overrides:
