Data Parallelism

Parallel patterns

Parallel execution patterns for composing algorithms.

Function	Description
parallel_for	Executes user code in parallel
parallel_reduce	Executes user code to perform a reduction in parallel
parallel_scan	Executes user code to generate a prefix sum in parallel
fence	Fences execution spaces

Built-in Reducers

Reducer objects used in conjunction with parallel_reduce.

Reducer	Description
BAnd	Binary 'And' reduction
BOr	Binary 'Or' reduction
LAnd	Logical 'And' reduction
LOr	Logical 'Or' reduction
Max	Maximum reduction
MaxLoc	Reduction providing maximum and an associated index
Min	Minimum reduction
MinLoc	Reduction providing minimum and an associated index
MinMax	Reduction providing both minimum and maximum
MinMaxLoc	Reduction providing both minimum and maximum and associated indices
Prod	Multiplicative reduction
Sum	Sum reduction
