This chapter helps you get the ProDev ProMP parallel analyzer view running on your system. It contains the following sections:
Setting up your system, see “Setting Up Your System”.
Running the parallel analyzer view: general features, see “Running the Parallel Analyzer View: General Features”.
Tutorials, see “Tutorials”.
|Note: This product was formerly called WorkShop Pro MPF.|
To install the ProDev ProMP software, you should have at least 16 MB of memory; 32 MB improves overall performance.
ProDev ProMP requires the following software versions (or later versions):
IRIX system software version 6.2
MIPSpro Auto-Parallelizing Fortran 77, release 7.2.1
MIPSpro Auto-Parallelizing Fortran 90, release 7.3
MIPSpro Auto-Parallelizing C, release 7.3
To determine what software is installed on your system, enter the following at the shell prompt:
If the items mentioned in this section are not installed, consult your sales representative, or in the United States call the Silicon Graphics Technical Assistance Center at 1-(800)-800-4SGI. To order additional memory, consult your sales representative or call 1-(800)-800-SGI1.
If you have all the software and memory you need, you can install the ProDev ProMP software.
For general instructions about software installation, consult the man pages inst(1m) and swmgr(1m), and the manual, IRIX Admin: Software Installation and Licensing.
See also Developer Magic: ProDev Pro MP Release Notes for specific installation instructions.
The executable is cvpav(1), which is installed in /usr/sbin.
The process of using the parallel analyzer view involves two steps:
Compiling a program with appropriate options.
Reading the compiled files with the parallel analyzer view.
Before starting the parallel analyzer view to analyze your source (in this case, Fortran source), run one of the auto-parallelizing compilers with the appropriate options. For the tutorials presented in subsequent chapters, makefiles are provided. You can adapt these to your specific source or enter one of the following commands:
% f90 -apo keep -O3 sourcefile.f % f77 -apo keep -O3 sourcefile.f
The compiler generates its usual output files and an analysis file ( sourcefile.anl), which the parallel analyzer reads.
The command-line options have the following effects:
Saves a .anl file, which has necessary information for the parallel analyzer view.
Sets the compiler for aggressive optimization. The optimization focuses on maximizing code performance, even if that requires extending the compile time or relaxing language rules.
See the MIPSpro Fortran 77 Programmer's Guide, MIPSpro Compiling and Performance Tuning Guide, and the f90(1) or f77(1) man page for more information.
|: The cvpav command assumes that the -apo keep option was used on each of the Fortran source files named in a single executable or file specifying several executables. If this is not the case, a warning message is posted, and the unprocessed files are marked by an error icon within the parallel analyzer's subroutines and files view, see “Subroutines and Files View” in Chapter 6.|
While they are not part of the parallel analyzer view, other parallelization reports can be generated using the following command-line options:
Produces a .l file, a listing of those parts of the program that can run in parallel and those that cannot.
Generates the equivalent parallelized program in a .w2f.f file.
These reports are text files that can be used for analysis. For more detailed information, see MIPSpro Auto-Parallelizing Option Programmer's Guide.
The MIPSpro auto-parallelizing Fortran compilers support OpenMP directives, unless you are compiling with the -o32 option. If you put OpenMP directives in your o32 code, they are treated as comments rather than being interpreted. For more information on OpenMP directives, see the following:
The OpenMP Architecture Review Board web site at the following URL: http://www.openmp.org/
Although using OpenMP directives is recommended, the auto-parallelizing compilers still support PCF directives. For information on analyzing loops containing PCF directives, see Appendix A, “Examining Loops Containing PCF Directives”.
You can run the parallel analyzer view on any of the following objects:
A source file
A list of files
To run the parallel analyzer view for one of these cases, enter one of the following commands:
% cvpav -f sourcefile.f % cvpav -e executable % cvpav -F fileset-file
The cvpav command reads information from all source files compiled into the application.
The parallel analyzer view has several other command line options, as well as several X Window System resources that you can set. See the man page cvpav(1)(1) for more information.
