Detailed Description

template<typename MapWF, bool b_coarse = false>
struct stapl::composition::map_factory< MapWF, b_coarse >

Factory implementing functional version of map_func which returns a view over the result of the mapping function applied to all elements. The input views are not mutated.

Template Parameters

MapWF	Type of the user provided workfunction.
b_coarse	Boolean computed internally signifying whether MapWF is an elemental workfunction or one pre-coarsened by the user.

Member Function Documentation

reset_view_indices()

void stapl::task_factory_base::reset_view_indices ( )

protectedinherited

Reset the iterators over the view indices on this location.

This is used in factories where multiple tasks will be generated for each view element to be processed.

get_location_md()

runtime::location_md& stapl::p_object::get_location_md ( void  )

noexceptinherited

Returns the location metadata of the location this object registered in. noexcept

noexcept

advance_epoch()

void stapl::p_object::advance_epoch ( void  )

inherited

Advances the epoch of the object.

Advancing the epoch will flush any pending RMIs. It will also increase the epoch of the current gang if the object is not a named object.

unlock()

void stapl::p_object::unlock ( void  )

inherited

Used by lock_guard functionality in method of derived classes to request atomicity with respect to incoming RMIs.

Mutates counter in the associated runqueue.

lock()

void stapl::p_object::lock ( void  )

inherited

Used by lock_guard functionality in method of derived classes to request atomicity with respect to incoming RMIs.

Mutates counter in the associated runqueue.

try_lock()

bool stapl::p_object::try_lock ( void  )

inherited

Attempt to maintain atomicity with respect to incoming RMIs.

Mutates counter in the associated runqueue.

Returns

true if the lock was able to be acquired. false if it is already locked.
