CNR branch to set. See Named Constants for CNR Control for a list of named constants that specify the settings.

The mkl_cbwr_set function configures the CNR mode. In this release, it sets the CNR branch and turns on the CNR mode.

Settings specified by the mkl_cbwr_set function take precedence over the settings specified by the MKL_CBWR environment variable.

Name	Type	Description
status	int	The status of the function completion: MKL_CBWR_SUCCESS - the function completed successfully. MKL_CBWR_ERR_INVALID_INPUT - an invalid setting is requested. MKL_CBWR_ERR_UNSUPPORTED_BRANCH - the input value of the branch does not match the instruction set architecture (ISA) of your system. See Named Constants for CNR Control for more details. MKL_CBWR_ERR_MODE_CHANGE_FAILURE - the mkl_cbwr_setfunction requested to change the current CNR branch after a call to some Intel® oneAPI Math Kernel Library function other than a CNR function.
