Sun Studio: High Performance and Technical Computing

Print-friendly Version

The following manuals cover a wide domain of information relevant to developing HPTC applications on Sun platforms.

Compilers and Tools 

• OpenMP API User`s Guide
  Summarizes the OpenMP Fortran 95, C, and C++ application program interface (API) for building multiprocessing applications. Sun compilers include native support the OpenMP API parallel programming model. (June, 2007)
 

• Program Performance Analyzer
  Developing high performance applications requires a combination of compiler features, libraries of optimized functions, and tools for performance analysis. This manual describes the tools that are available to help you assess the performance of your code, identify potential performance problems, and locate the part of the code where the problems occur. Described are the Collector and Performance Analyzer, a pair of tools that you use to collect and analyze performance data for your application. Both tools can be used from the command line or from a graphical user interface. (June, 2007)
 

• Sun Studio Thread Analyzer User`s Guide
  Details on compiling and running multi-threaded programs with the Thread Analyzer to detect deadlocks and data races. (June, 2007)
 

• Sun Performance Library User`s Guide
  Explains the Sun-specific enhancements to the LINPACK and BLAS routines available from Netlib. Reference material describing the base routines is available from Netlib and the Society for Industrial and Applied Mathematics (SIAM). (June, 2007)
 

• Sun Performance Library Reference Manual
  The Sun Performance Library section 3P man pages give full synopses of all the routines, available in HTML and PDF formats. (June, 2007)
 

• C User`s Guide
  Details the Sun C compiler's command-line options, pragma directives, supported ISO/IEC 9899:1999 features, and the lint code-checking program. There are also several appendices with reference material such as ISO C data representations, implementation defined behavior, the differences between Sun C (K & R) and Sun ISO C, performance tuning, and converting applications to compile for the 64-bit environment. (June, 2007)
 

• Fortran User`s Guide
  Details the environment and command-line options for the Sun Fortran 95 compiler f95, including Fortran 77 compatibility options and parallelization. (June, 2007)
 

• Fortran Programming Guide
  Provides information essential for programming efficient Fortran 95 applications with the Sun compiler f95. It covers topics such as Fortran 95 input/output, program development, libraries, program analysis and debugging, numerical accuracy, porting, performance, optimization, parallelization, and interoperability. (June, 2007)
   

• Debugging a Program with dbx
  Complete reference for using the debugging tools and how to interpret the results. (June, 2007)

Technical Articles

Sun Studio for Multithreaded Programming

Use the parallel programming features in Sun Studio compilers to develop high performance multithreaded applications on multi-core, multi-processor platforms.

The Sun Studio Performance Tools <

The Sun Studio performance tools are designed to help answer questions about application performance. This article discusses the kinds of performance questions that users typically ask. It describes the model for using the tools, and for building the target executable, as well as the data collection process, and the data that can be collected. The Analyzer and its displays are also described, along with a number of examples of what it can do.  (November 10, 2005)
