I installed Inte Parallel Studio XE 2018 Composer on WSL Ubuntu on Windows 10. In November, 2017, I tried to install it as posted here (in Japanese), it was not successful. This time I successfully installed it on Windows 10 ver. 1803 issued in April, 2018.
Download [cci]Version 2018 (Update 2) March 21, 2018[/cci] from the license administration server in here and save it in an appropriate directory and extract it. Move to the extracted directory and invoke [cci]install_sh[/cci].
$ tar xf parallel_studio_xe_2018_update2_composer_edition_online.tgz
$ cd parallel_studio_xe_2018_update2_composer_edition_online
$ sudo ./install.sh
Just follow the instruction. Basically the default values are fine.
After completing the installation, invoke a tool as follows to set up its environment variables.
$ cd /opt/intel/parallel_studio_xe_2018
$ source ./psxevars.sh
Now you can test making some simple code ([cci]test.f90[/cci]), compile it and execute [cci]a.out[/cci].
$ ifort test.f90
