From cppreference.com
The C++ Extensions for Parallelism, ISO/IEC TS 19570:2015 defines the following new components for the C++ standard library:

Exception lists
| Defined in header
<experimental/exception_list> | |
| exceptions raised during parallel executions (class) | |

New algorithms
| Defined in header
<experimental/algorithm> | |
| similar to std::for_each except returns void (function template) | |
| applies a function object to the first n elements of a sequence (function template) | |
| Defined in header
<experimental/numeric> | |
| similar to std::accumulate, except out of order (function template) | |
| similar to std::partial_sum, excludes the ith input element from the ith sum (function template) | |
| similar to std::partial_sum, includes the ith input element in the ith sum (function template) | |
| applies a functor, then reduces (function template) | |
| applies a functor, then calculates exclusive scan (function template) | |
| applies a functor, then calculates inclusive scan (function template) | |
