Before You Begin

This book describes how to use the Sun specific extensions and features included with the Sun Performance Library subroutines that are supported by the Sun Forte Developer Fortran 95 and C compilers.

Who Should Use This Book

This book is a user's guide intended for programmers who have a working knowledge of the Fortran or C language and some understanding of the base LAPACK and BLAS libraries available from Netlib (http://www.netlib.org).

How This Book Is Organized

This book is organized into the following chapters and appendixes:

Chapter 1 describes the benefits of using the Sun Performance Library and the features of the Sun Performance Library.

Chapter 2 describes how to use the f95 and C interfaces provided with the Sun Performance Library.

Chapter 3 shows how to use compiler and linking options to maximize library performance for specific SPARC instruction set architectures and different parallel processing modes.

Chapter 4 includes information on matrix storage schemes, matrix types, and sparse matrices.

Chapter 5 describes the one-dimensional, two-dimensional, and three-dimensional fast Fourier transform routines provided with the Sun Performance Library.

Chapter 6 provides an introduction to the Interval Basic Linear Algebra Subroutine (IBLAS) library provided with the Sun Performance Library.

Appendix A lists the Sun Performance Library routines organized according to name, routine, and library.

What Is Not in This Book

This book does not repeat information included in existing LAPACK books or sources on Netlib. Refer to the next section Related Documents and Web Sites for a list of sources that contain reference material for the base routines upon which Sun Performance Library is based.

Accessing Forte Developer Development Tools and Man Pages

The Forte Developer product components and man pages are not installed into the standard /usr/bin/ and /usr/share/man directories. To access the Forte Developer compilers and tools, you must have the Forte Developer component directory in your PATH environment variable. To access the Forte Developer man pages, you must have the Forte Developer man page directory in your MANPATH environment variable.

For more information about the PATH variable, see the csh(1), sh(1), and ksh(1) man pages. For more information about the MANPATH variable, see the man(1) man page. For more information about setting your PATH and MANPATH variables to access this Forte Developer release, see the installation guide or your system administrator.

Note - The information in this section assumes that your Forte Developer products are installed in the /opt directory. If your product software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.

Accessing Forte Developer Compilers and Tools

Use the steps below to determine whether you need to change your PATH variable to access the Forte Developer compilers and tools.

To Determine Whether You Need to Set Your PATH Environment Variable

1. Display the current value of the PATH variable by typing the following at a command prompt:

% echo $PATH

2. Review the output for a string of paths that contain /opt/SUNWspro/bin/.

If you find the path, your PATH variable is already set to access Forte Developer development tools. If you do not find the path, set your PATH environment variable by following the instructions in the next section.

To Set Your PATH Environment Variable to Enable Access to Forte Developer Compilers and Tools

1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.

2. Add the following to your PATH environment variable.

/opt/SUNWspro/bin

Accessing Forte Developer Man Pages

Use the following steps to determine whether you need to change your MANPATH variable to access the Forte Developer man pages.

To Determine Whether You Need to Set Your MANPATH Environment Variable

1. Request the dbx man page by typing the following at a command prompt:

% man dbx

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 installed, follow the instructions in the next section for setting your MANPATH environment variable.

To Set Your MANPATH Environment Variable to Enable Access to Forte Developer Man Pages

1. If you are using the C shell, edit your home .cshrc file. If you are using the Bourne shell or Korn shell, edit your home .profile file.

2. Add the following to your MANPATH environment variable.

/opt/SUNWspro/man
