Member Function Documentation

bindThread()

virtual void Arcane::IProcessorAffinityService::bindThread ( Int32 cpu )

pure virtual

Constrains the current thread to stay on the core with index cpu.

Implemented in Arcane::HWLocProcessorAffinityService.

cpuSetString()

virtual String Arcane::IProcessorAffinityService::cpuSetString ( )

pure virtual

Returns the cpuset for the current thread.

The returned string is in a format compatible with that of taskset. For example, we can have values such as 'ff', '1, or 'ffff1234,ff'.

Implemented in Arcane::HWLocProcessorAffinityService.

numberOfCore()

virtual Int32 Arcane::IProcessorAffinityService::numberOfCore ( )

pure virtual

numberOfProcessingUnit()

virtual Int32 Arcane::IProcessorAffinityService::numberOfProcessingUnit ( )

pure virtual

Number of logical cores (-1 if unknown).

numberOfSocket()

virtual Int32 Arcane::IProcessorAffinityService::numberOfSocket ( )

pure virtual

Number of sockets (-1 if unknown).

Implemented in Arcane::HWLocProcessorAffinityService.

printInfos()

virtual void Arcane::IProcessorAffinityService::printInfos ( )

pure virtual

Displays complete topology information via info().
