Types

type CpuSet

type CpuSet []uint16

CpuSet: a set of cpus generally linked in some way that affects performance

func (s CpuSet) Contains(c uint16) bool

func (CpuSet) ContainsCSib

func (s CpuSet) ContainsCSib(c uint16) bool

check for core siblings

func (CpuSet) ContainsTSib

func (s CpuSet) ContainsTSib(c uint16) bool

check for thread siblings
