Sequential, parallel, or parallel execution with vectorisation

Sequential, parallel, or parallel execution with vectorisation

We will now learn how to execute our algorithm according to a certain execution policy.

By using an execution policy in C++17, you can specify whether the algorithm should run sequentially, in parallel, or in parallel with vectorization.

Execution Policies

The policy tag specifies whether an algorithm should run sequentially, in parallel, or in parallel with vectorization.

  • std::execution::seq: runs the algorithm sequentially

  • std::execution::par: runs the algorithm in parallel on ...
