Description

This function returns the current value of the MKL_DYNAMIC variable. This variable can be changed by manipulating the MKL_DYNAMIC environment variable before the Intel MKL run is launched or by calling mkl_set_dynamic(). Doing the latter has precedence over the former.

The function returns a value of 0 or 1: 1 indicates that MKL_DYNAMIC is true, 0 indicates that MKL_DYNAMIC is false. This variable indicates whether or not Intel MKL can dynamically change the number of threads. A value of false does not guarantee that the number of threads you requested will be used. But it means that Intel MKL will attempt to use that value.

Note that if Intel MKL is called from within a parallel region, Intel MKL may not thread unless MKL_DYNAMIC is set to false, either with the environment variable or by this routine call.

See Intel MKL User's Guide for implementation details.

Return Values

1

Indicates MKL_DYNAMIC is true.

0

Indicates MKL_DYNAMIC is false.
