  • 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
