Setting the Environment Variables for Threading Control

To set the environment variables used for threading control, in the command shell in which the program is going to run, enter
the
export
or
setenv
commands, depending on the shell you use.
For a bash shell, use the
export
commands:
export
<VARIABLE NAME>
=
<value>
For example:
export MKL_NUM_THREADS=4
export MKL_DOMAIN_NUM_THREADS="MKL_DOMAIN_ALL=1, MKL_DOMAIN_BLAS=4"
export MKL_DYNAMIC=FALSE
export MKL_NUM_STRIPES=4
For the csh or tcsh shell, use the
setenv
commands:
setenv
<VARIABLE NAME>
<value>
.
For example:
setenv MKL_NUM_THREADS 4
setenv MKL_DOMAIN_NUM_THREADS "MKL_DOMAIN_ALL=1, MKL_DOMAIN_BLAS=4"
setenv MKL_DYNAMIC FALSE
setenv MKL_NUM_STRIPES 4
