## Field Details

### nodeNumber

public int nodeNumber
Identifies the NUMA node. Valid values are `0` to the highest NUMA node number inclusive. A non-NUMA multiprocessor system will report that all processors belong to one NUMA node.

### reserved

public byte[] reserved
This member is reserved.

### groupCount

public short groupCount
The number of groups included in the GroupMasks array. This field was introduced in TBD Release Iron. On earlier versions, this value is always 0.

### groupMask

public WinNT.GROUP_AFFINITY groupMask
A `WinNT.GROUP_AFFINITY` structure that specifies a group number and processor affinity within the group. This member is only relevant if `groupCount` is 0.

### groupMasks

public WinNT.GROUP_AFFINITY[] groupMasks
An array of `WinNT.GROUP_AFFINITY` structures that specifies a group number and processor affinity within the group. This member is only relevant if `groupCount` is 1 or greater.
