Preparing the Sample Application

In this tutorial, you will 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:
  1. Open a terminal session.
  2. 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 architecture only
    intel64
    Compiler and libraries for Intel® 64 architecture only
    IA-32 is not available on macOS*.
