gmx::HardwareTopology::LogicalProcessor Struct Reference

#include <gromacs/hardware/hardwaretopology.h>

Description

Information about package, core and processing unit for a logical processor.

Note

In general, not all logical processors in the system will be visible, so the osId field can be larger than the total number of processing units in the topology.

The indices of packages, cores and PUs correspond to the indices in this hardware topology, rather than the global/physical rank in the system, meaning they are consistent with the contents of the vectors in the machine.packags[].cores[].processingUnits[] hierarchy.

Public Attributes
int	puId
	Index of PU in hardware topology.
int	osId
	index assigned by the operating system
int	packageRankInTopology
	index of package in machine
int	coreRankInPackage
	index of core in package
int	processingUnitRankInCore
	index of processing unit in core
int	numaNodeId
	Index of numa node.
bool	isAssignedToProcess
	Whether this PU is a part of process affinity set.
