Extensions for parallelism, version 2
< cpp | experimental
The C++ Extensions for Parallelism Version 2, ISO/IEC TS 19570:2018 defines the following new components for the C++ standard library:
Parallel exceptions
|
Defined in header
<experimental/exception_list> |
|
| exceptions raised during parallel executions (class) |
|
Execution policies
|
Defined in header
<experimental/execution_policy> |
|
| execution policy types (class) |
|
| global execution policy objects (constant) |
|

Data-Parallel Types
|
(parallelism TS v2)
|
data-parallel vector type (class template) |
|
(parallelism TS v2)
|
data-parallel type with the element type bool (class template) |
Feature test macros
|
Defined in header
<experimental/task_block> |
|
|
__cpp_lib_experimental_parallel_task_block
|
a value of at least 201711 indicates that the task block functionality is supported (macro constant) |
|
Defined in header
<experimental/execution> |
|
|
__cpp_lib_experimental_execution_vector_policy
|
a value of at least 201711 indicates that the vector and wavefront policies are supported (macro constant) |
|
Defined in header
<experimental/algorithm> |
|
|
__cpp_lib_experimental_parallel_for_loop
|
a value of at least 201711 indicates that the for_loop class of algorithms is supported(macro constant) |
|
Defined in header
<experimental/simd> |
|
|
__cpp_lib_experimental_parallel_simd
|
a value of at least 201803 indicates that the data-parallel types library is supported (macro constant) |
