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

[edit] Task Block
| This section is incomplete |
[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
| 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) |
