Setting Environment Variables for Automatic Offload

Important

To use Automatic Offload:

To set the environment variables for Automatic Offload mode, described in Automatic Offload Controls, use the appropriate commands:

set MKL_MIC_ENABLE=1

set OFFLOAD_DEVICES=<list>

For example: set OFFLOAD_DEVICES=1,3

set OFFLOAD_ENABLE_ORSL=1

set MKL_HOST_WORKDIVISION=<value>

For example: set MKL_HOST_WORKDIVISION=0.2

set MKL_MIC_WORKDIVISION=<value>

set MKL_MIC_<number>_WORKDIVISION=<value>

For example: set MKL_MIC_2_WORKDIVISION=0.33

set MKL_MIC_MAX_MEMORY=<value>

set MKL_MIC_<number>_MAX_MEMORY=<value>

For example: set MKL_MIC_0_MAX_MEMORY=2G

set MKL_MIC_REGISTER_MEMORY=1

set MKL_MIC_RESOURCE_LIMIT=<value>

For example: set MKL_MIC_RESOURCE_LIMIT=0.34

set MIC_OMP_NUM_THREADS=<value>

set MIC_<number>_OMP_NUM_THREADS=<value>

For example: set MIC_0_OMP_NUM_THREADS=240

set OFFLOAD_REPORT=<level>

For example: set OFFLOAD_REPORT=2

set MKL_MIC_THRESHOLDS_?GEMM="<N>,<M>,<K>"

For example: set MKL_MIC_THRESHOLDS_?GEMM="2000,1000,500"
