Before You Begin
The OpenMP API User's Guide summarizes the OpenMP Fortran 95, C, and C++ application program interface (API) for building multiprocessing applications. Sun Studio compilers support the OpenMP API.
This guide is intended for scientists, engineers, and programmers who have a working knowledge of the Fortran, C, or C++ languages, and the OpenMP parallel programming model. Familiarity with the Solaris operating environment or UNIX® in general is also assumed.
This Sun Studio release supports systems that use the SPARC® and x86 families of processor architectures: UltraSPARC®, SPARC64, AMD64, Pentium, and Xeon EM64T. The supported systems for the version of the Solaris Operating System you are running are available in the hardware compatibility lists at http://www.sun.com/bigadmin/hcl. These documents cite any implementation differences between the platform types.
In this document, these x86 related terms mean the following:
For supported systems, see the hardware compatibility lists.
The Sun Studio software and its man pages are not installed into the standard /usr/bin/ and /usr/share/man directories. To access the software, you must have your PATH environment variable set correctly (see Accessing the Software). To access the man pages, you must have your MANPATH environment variable set correctly (see Accessing the Man Pages).
For more information about the PATH variable, see the csh(1), sh(1), ksh(1), and bash(1) man pages. For more information about the MANPATH variable, see the man(1) man page. For more information about setting your PATH variable and MANPATH variable to access this release, see the installation guide or your system administrator.
Note - The information in this section assumes that your Sun Studio software is installed in the /opt directory on Solaris platforms and in the /opt/sun directory on Linux platforms. If your software is not installed in the default directory, ask your system administrator for the equivalent path on your system.
Use the steps below to determine whether you need to change your PATH variable to access the software.
1. Display the current value of the PATH variable by typing the following at a command prompt.
2. On Solaris platforms, review the output to find a string of paths that contain /opt/SUNWspro/bin. On Linux platforms, review the output to find a string of paths that contain /opt/sun/sunstudio11/bin.
If you find the path, your PATH variable is already set to access the software. If you do not find the path, set your PATH environment variable by following the instructions in the next procedure.
On Solaris platforms, add the following path to your PATH environment variable. If you have previously installed Forte Developer software, Sun ONE Studio software, or another release of Sun Studio software, add the following path before the paths to those installations.
On Linux platforms, add the following path to your PATH environment variable.
Use the following steps to determine whether you need to change your MANPATH variable to access the man pages.
1. Request the dbx man page by typing the following at a command prompt.
2. Review the output, if any.
If the dbx(1) man page cannot be found or if the man page displayed is not for the current version of the software, follow the instructions in the next procedure to set your MANPATH environment variable.
On Solaris platforms, add the following path to your MANPATH environment variable.
On Linux platforms, add the following path to your MANPATH environment variable.
The Sun Studio integrated development environment (IDE) provides modules for creating, editing, building, debugging, and analyzing the performance of a C, C++, or Fortran application.
The command to start the IDE is sunstudio. For details on this command, see the sunstudio(1) man page.
The correct operation of the IDE depends on the IDE being able to find the core platform. The sunstudio command looks for the core platform in two locations:
If the core platform is not installed or mounted to either of the locations where the sunstudio command looks for it, then each user on a client system must set the environment variable SPRO_NETBEANS_HOME to the location where the core platform is installed or mounted (/installation_directory/netbeans/3.5V11).
On Solaris platforms, each user of the IDE also must add /installation_directory/SUNWspro/bin to their $PATH in front of the path to any other release of Forte Developer software, Sun ONE Studio software, or Sun Studio software. On Linux platforms, each user of the IDE also must add /installation_directory/sunstudio11/bin to their $PATH in front of the path to any other release of Sun Studio software.
The path /installation_directory/netbeans/3.5V11/bin should not be added to the user's $PATH.

If your software is not installed in the /opt directory on a Solaris platform or the /opt/sun directory on a Linux platform, ask your system administrator for the equivalent path on your system.
