Detailed Description

Allocate space for reduction operations to store temporary accumulations, bridging the gap between gathering and scattering operations.

Constructor & Destructor Documentation

ReductionBridge() [1/2]

stormm::stmath::ReductionBridge::ReductionBridge

(

size_t

n_values

)

The constructor allocates space in all three buffers for a set amount of data.

Parameters

n_values

The number of intermediate values to store, most likely determined by the number of reduction work units

ReductionBridge() [2/2]

stormm::stmath::ReductionBridge::ReductionBridge

(

const ReductionBridge &

original

)

The copy and copy assignment operators must deal with pointer repair.

Parameters

original	The original object to copy or move
other	Another object to copy or move

Member Function Documentation

getPointer()

const double * stormm::stmath::ReductionBridge::getPointer	(	CartesianDimension	cdim,
		HybridTargetLevel	tier = HybridTargetLevel::HOST ) const

Get pointers to one of the buffers.

Overloaded:

• Get a const pointer to a const form of this object's data
• Get a non-const pointer to a non-const form of this object's data

Parameters

cdim	The "dimension" to obtain a pointer for
tier	Obtain pointers to host or device data
