Open a terminal.

If you did not set up oneAPI toolkit environment permanently: Set up environment variables:

For root or sudo users:

source /opt/intel/oneapi/setvars.sh

For non-root users:

source ~/intel/oneapi/setvars.sh

See Set up Environment Variables for other options.

If you installed the Render Kit to a custom location, make sure to replace

/opt/intel/oneapi/

(for root or sudo users) or

~/intel/oneapi/

(for non-root users) with the custom installation path before running the command.

Go to a writable directory and create a directory to store supporting and result files.

For example, create the

rk_gsg

folder

:

cd ~

mkdir rk_gsg

cd rk_gsg
