mkl_domain_set_num

Suggests the number of threads for a particular function domain.

Syntax

FORTRAN:

ierr = mkl_domain_set_num_threads( num, mask )

ierr = mkl_domain_set_num_threads( num, mask );

num

FORTRAN: INTEGER

Number of threads suggested by user

mask

FORTRAN: INTEGER

C: int

Name of the targeted domain

Description

This function allows you to request different domains of Intel MKL to use different numbers of threads. The currently supported domains are:

MKL_DOMAIN_BLAS - BLAS
MKL_DOMAIN_FFT - FFT (excluding cluster FFT)
MKL_DOMAIN_VML - Vector Math Library
MKL_DOMAIN_PARDISO - PARDISO
MKL_DOMAIN_ALL - another way to do what mkl_set_num_threads does

This is only a hint, and use of this number of threads is not guaranteed. Enter a valid domain and a positive integer for the number of threads. This routine has precedence over the MKL_DOMAIN_NUM_THREADS environment variable.

See Intel MKL User's Guide for implementation details.

Return Values

1(true): Indicates no error, execution is successful.
0(false): Indicates failure, possibly because the inputs were invalid.
