To begin this tutorial, you need to get the source files for the sample application and set the environment variables to use the compiler.
Locate the source files in the product's Samples directory:
<install-dir>/Samples/<locale>/Fortran/vec_samples
Use the following files:
-
driver.f90
-
matvec.f90
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
