OpenMPController (version 0.2-5)

omp_set_num_threads: Set number of OpenMP threads

Description

Sets the number of OpenMP threads to be used. This may be useful, for example, when linking against a vendor optimised BLAS/LAPACK library (e.g. the AMD Core Math Library), since the defaults used by those libraries may not be highly performant.

Usage

omp_set_num_threads(n)

Arguments

n

Integer, number of threads

Examples

# NOT RUN {
omp_set_num_threads(2)

# do something requiring 2 OMP threads

omp_set_num_threads(4)

# do something else requiring 4 OMP threads
# }
