Setting the Environment Variable for Conditional Numerical Reproducibility
The following examples illustrate the use of the MKL_CBWR environment variable. The first command sets Intel® oneAPI Math Kernel Library (oneMKL) to run in the CNR mode based on the default dispatching for your platform. The other two commandsare equivalent and set the CNR branch to Intel AVX2:
- set MKL_CBWR=AUTO
- set MKL_CBWR=AVX2
- set MKL_CBWR=BRANCH=AVX2
