Detailed Description

Implementation of a kernel-level thread as processing unit for the pthreads backend.

This implementation uses Pthreads as backend for the creation and management of OS threads.

Constructor & Destructor Documentation

ProcessingUnit()

__INLINE__ HiCR::backend::pthreads::ProcessingUnit::ProcessingUnit ( const std::shared_ptr< HiCR::ComputeResource > &  computeResource )

inline

Constructor for the ProcessingUnit class

Parameters

computeResource

Represents the compute resource (core) affinity to associate this processing unit to

Member Function Documentation

getAffinity()

static __INLINE__ std::set< HiCR::backend::hwloc::ComputeResource::logicalProcessorId_t > HiCR::backend::pthreads::ProcessingUnit::getAffinity ( )

inlinestatic

Queries the OS for the currently set affinity for this thread, and prints it to screen.

Returns

The set of cores/processing units that this thread is bound to

getType()

__INLINE__ std::string HiCR::backend::pthreads::ProcessingUnit::getType ( )

inlineoverridevirtual

Gets the processing unit's type

Returns

A string, containing the processing unit's type

Implements HiCR::ProcessingUnit.

updateAffinity()

static __INLINE__ void HiCR::backend::pthreads::ProcessingUnit::updateAffinity ( const std::set< hwloc::ComputeResource::logicalProcessorId_t > &  affinity )

inlinestatic

Sets up new affinity for the thread. The thread needs to yield or be preempted for the new affinity to work.

Parameters

[in]

affinity

New affinity to use
