Functions
- void parallel_for(int begin, int end, int step, std::function<void(int, size_t)> body, size_t num_threads = 0)
- Executes the body of a for loop in parallel.
- void parallel_for(int begin, int end, int step, std::function<void(int)> body, size_t num_threads = 0)
- A version of the parallel_for accepting a body lambda that only takes the iterator index as a parameter.
- void parallel_for(int begin, int end, std::function<void(int, size_t)> body, size_t num_threads = 0)
- A version of parallel_for with a step of 1, providing the integer index and thread number to the loop
body. - void parallel_for(int begin, int end, std::function<void(int)> body, size_t num_threads = 0)
- A version of parallel_for with a step of 1, providing just the integer index to the loop
body.
Function documentation
void parallel_for(int begin, int end, int step, std::function<void(int, size_t)> body, size_t num_threads = 0)
Executes the body of a for loop in parallel.
| Parameters | |
|---|---|
| begin | The starting index of the for loop |
| end | One past the ending index of the for loop |
| step | How much to increment at each iteration when moving from begin to end |
| body | The body of the for loop as a lambda, taking two parameters: the iterator index in [begin,end), and the CPU number. |
| num_threads | Specify the number of threads to use. 0: as many as there are cores; 1: execute in serial |
