flags
public byte flagsIf theWinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationshipmember of theWinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EXstructure isWinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore, this member isWinNT.LTP_PC_SMTif the core has more than one logical processor, or 0 if the core has one logical processor.If the
WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationshipmember of theWinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EXstructure isWinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorPackage, this member is always 0. -
efficiencyClass
public byte efficiencyClassIf theWinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationshipmember of theWinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EXstructure isWinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorCore, EfficiencyClass specifies the intrinsic tradeoff between performance and power for the applicable core. A core with a higher value for the efficiency class has intrinsically greater performance and less efficiency than a core with a lower value for the efficiency class. EfficiencyClass is only nonzero on systems with a heterogeneous set of cores.If the
WinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX.relationshipmember of theWinNT.SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EXstructure isWinNT.LOGICAL_PROCESSOR_RELATIONSHIP.RelationProcessorPackage, EfficiencyClass is always 0.The minimum operating system version that supports this member is Windows 10.

reserved
public byte[] reservedThis member is reserved. -
groupCount
public short groupCountThis member specifies the number of entries in the GroupMask array.If the PROCESSOR_RELATIONSHIP structure represents a processor core, the GroupCount member is always 1.
If the
WinNT.PROCESSOR_RELATIONSHIPstructure represents a processor package, thegroupCountmember is 1 only if all processors are in the same processor group. If the package contains more than one NUMA node, the system might assign different NUMA nodes to different processor groups. In this case, thegroupCountmember is the number of groups to which NUMA nodes in the package are assigned. -
groupMask
An array ofWinNT.GROUP_AFFINITYstructures. ThegroupCountmember specifies the number of structures in the array. Each structure in the array specifies a group number and processor affinity within the group.
