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.

Installation

Download Version 2018 (Update 2) March 21, 2018 from the license administration server in here and save it in an appropriate directory and extract it. Move to the extracted directory and invoke install_sh.

$ 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 (test.f90), compile it and execute a.out.

$ ifort test.f90
$ ./a.out
