I just installed Intel® Parallel Studio XE Cluster Edition for Windows (I have Windows 7, 64 bit) because I want to evaluate the fortran compiler. I have the 30-day free trial. I do not have Microsoft Visual Studio so I was hoping to simply use the command tool to launch the fortran compiler. However the ifort command is not recognized. I followed the instructions below, "for other versions of Windows".
Open a command prompt.
Open the Start menu, and under the Intel Parallel Studio XE 2019 product group, select a compiler command prompt.
Other versions of Windows*
Open the Start menu and under Intel Parallel Studio XE 2019 > Compiler and Performance Libraries > Command prompt with Intel Compiler, select a build environment.
Invoke the compiler as follows:
ifort [options... ] inputfile(s) [/link link_options]
Use the command ifort /help to display all available compiler options.
Current versions of Intel Fortran require Visual Studio to be installed. The free Community Edition will suffice.
