To begin this tutorial, get the source file for the sample application from the Samples directory and set the environment variables to use the compiler. The source file is in the following directory:
<install-dir>/Samples/<locale>/Fortran/coarray_samples/hello_image.f90
Copy hello_image.f90 to a working directory where you have write and execute permissions.
Note
The Intel® Fortran Compiler implementation of coarrays follows the standard provided in a draft version of the Fortran 2008 standard. Not all features present in the Fortran 2008 standard may be implemented by Intel. Consult the Release Notes for a list of supported features.
Setting the Environment Variables
Before you can use the compiler, you must first set the environment variables by running the compiler environment script compilervars.sh or compilervars.csh with an argument that specifies the target architecture.
To set the environment variables:
-
Open a terminal session.
-
Run one of the scripts with the appropriate architecture argument. The following example uses compilervars.sh:
source <install-dir>/bin/compilervars.sh <arg>
where <install-dir> is the directory structure containing the /bin directory and <arg> is one of the following architecture arguments:
- ia32 Compiler and libraries for IA-32 architectures only
- intel64 Compilers and libraries for Intel® architectures only
