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
Studio Fortran 95 and C compilers.
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).
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.
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.
A number of books and web sites provide reference information on the routines in the base LAPACK and BLAS libraries upon which the Sun Performance Library is based. The LAPACK Users' Guide. 3rd ed., Anderson E. and others. SIAM, 1999, augments the material in this manual and provide essential information:
The LAPACK Users' Guide, 3rd ed. is the official reference for the base LAPACK version 3.0 routines. An online version of the LAPACK 3.0 Users' Guide is available at http://www.netlib.org/lapack/lug/, and the printed version is available from the Society for Industrial and Applied Mathematics (SIAM) http://www.siam.org.
Sun Performance Library routines contain performance enhancements, extensions, and features not described in the LAPACK Users' Guide. However, because Sun Performance Library maintains compatibility with the base LAPACK routines, the LAPACK Users' Guide can be used as a reference for the LAPACK routines and the Fortran interfaces.
Online information describing the performance library routines that form the basis of the Sun Performance Library can be found at the following URLs.

Note - LINPACK has been removed from the Sun Performance Library. The LINPACK libraries and documentation are still available from www.netlib.org. |
The "pipe" or "bar" symbol separates arguments, only one of which may be chosen. |

The colon, like the comma, is sometimes used to separate arguments. |

The compilers and tools and their man pages are not installed into the standard /usr/bin/ and /usr/share/man directories. To access the compilers and tools, you must have your PATH environment variable set correctly (see Accessing the Compilers and Tools). To access the man pages, you must have the your MANPATH environment variable set correctly (see Accessing the Man Pages.).
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 variable and MANPATH variables to access this release, see the installation guide or your system administrator.
Use the steps below to determine whether you need to change your PATH variable to access the compilers and tools.
|
1. Display the current value of the PATH variable by typing the following at a command prompt.
2. Review the output to find a string of paths that contain /opt/SUNWspro/bin/.
If you find the path, your PATH variable is already set to access the compilers and tools. If you do not find the path, set your PATH environment variable by following the instructions in the next procedure.
|
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. If you have Sun ONE Studio software or Forte Developer software installed, add the following path before the paths to those installations.
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.
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 procedure for setting your MANPATH environment variable.
|
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.
The Sun Studio 8 integrated development environment (IDE) provides modules for creating, editing, building, debugging, and analyzing the performance of a C, C++, or Fortran application.
The IDE requires the Core Platform component of Sun Studio 8. You must set the SPRO_NETBEANS_HOME environment variable to the location where the Core Platform component is installed or mounted (installation_directory/netbeans/3.5R) if the Core Platform component is not installed or mounted to one of the following locations:
The command to start the IDE is sunstudio. For details on this command, see the sunstudio(1) man page.
You can access the documentation at the following locations:
If your software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.
The docs.sun.com web site (http://docs.sun.com) enables you to read, print, and buy Sun Microsystems manuals through the Internet. If you cannot find a manual, see the documentation index that is installed with the software on your local system or network.
The documentation is provided in accessible formats that are readable by assistive technologies for users with disabilities. You can find accessible versions of documentation as described in the following table. If your software is not installed in the /opt directory, ask your system administrator for the equivalent path on your system.
