Constructor & Destructor Documentation

TBBPartitioner()

parallel::internal::TBBPartitioner::TBBPartitioner

(

)

Constructor.

Definition at line 57 of file parallel.cc.

~TBBPartitioner()

parallel::internal::TBBPartitioner::~TBBPartitioner

(

)

Destructor. Check that the object is not in use any more, i.e., all loops have been completed.

Definition at line 64 of file parallel.cc.

Member Function Documentation

acquire_one_partitioner()

std::shared_ptr< tbb::affinity_partitioner > parallel::internal::TBBPartitioner::acquire_one_partitioner

(

)

Return an affinity partitioner. In case the partitioner owned by the class is free, it is returned here. In case another thread has not released it yet, a new object is created. To free the partitioner again, return it by the release_one_partitioner() call.

Definition at line 75 of file parallel.cc.

release_one_partitioner()

void parallel::internal::TBBPartitioner::release_one_partitioner

(

std::shared_ptr< tbb::affinity_partitioner > &

p

)

After using the partitioner in a tbb loop through acquire_one_partitioner(), this call makes the partitioner available again.

Member Data Documentation

my_partitioner

std::shared_ptr<tbb::affinity_partitioner> parallel::internal::TBBPartitioner::my_partitioner

private

The stored partitioner that can accumulate knowledge over several runs of tbb::parallel_for

Definition at line 604 of file parallel.h.

in_use

bool parallel::internal::TBBPartitioner::in_use

private

A flag to indicate whether the partitioner has been acquired but not released yet, i.e., it is in use somewhere else.

Definition at line 610 of file parallel.h.

mutex

std::mutex parallel::internal::TBBPartitioner::mutex

private

A mutex to guard the access to the in_use flag.
