In quitefastmst: Euclidean and Mutual Reachability Minimum Spanning Trees

Get or Set the Number of Threads

Description

These functions get or set the maximal number of OpenMP threads that can be used by knn_euclid and mst_euclid, amongst others.

Usage

omp_set_num_threads(n_threads)

omp_get_max_threads()

Arguments

n_threads

maximal number of threads to use

Value

omp_get_max_threads returns the maximal number of threads that will be used during the next call to a parallelised function, not the maximal number of threads possibly available. It there is no built-in support for OpenMP, 1 is always returned.

For omp_set_num_threads, the previous value of max_threads is returned.
