[edit] Execution policies

execution policy types
(class)
global execution policy objects
(constant)

[edit] Parallel algorithms

[edit] Task Block

[edit] Data-Parallel Types

(parallelism TS v2)
data-parallel vector type
(class template) [edit]
(parallelism TS v2)
data-parallel type with the element type bool
(class template) [edit]

[edit] Feature test macros
