PGI User's Guide

Chapter 11. Distributing Files - DeploymentPrograms can use PGI Unified Binary technology even if all of the object files and libraries are not compiled asunified binaries. Like any other object file, you can use PGI Unified Binary object files to create programs orlibraries. No special start up code is needed; support is linked in from the PGI libraries.The -Mpfi option disables generation of PGI Unified Binary object files. Instead, the default target auto-detectrules for the host are used to select the target processor.PGI Unified Binary Command-line SwitchesThe PGI Unified Binary command-line switch is an extension of the target processor switch, -tp, which maybe applied to individual files during compilation .The target processor switch, -tp, accepts a comma-separated list of 64-bit targets and generates codeoptimized for each listed target.The following example generates optimized code for three targets:-tp k8-64,p7-64,core2-64A special target switch, -tp x64, is the same as -tp k8-64, p7-64s.PGI Unified Binary Directives and PragmasPGI Unified binary directives and pragmas may be applied to functions, subroutines, or whole files. Thedirectives and pragmas cause the compiler to generate PGI Unified Binary code optimized for one or moretargets. No special command line options are needed for these pragmas and directives to take effect.The syntax of the Fortran directive is this:pgi$[g|r| ] pgi tp [target]...where the scope is g (global), r (routine) or blank. The default is r, routine.For example, the following syntax indicates that the whole file, represented by g, should be optimized for bothk8_64 and p7_64.pgi$g pgi tp k8_64 p7_64The syntax of the C/C++ pragma is this:#pragma [global|routine|] tp [target]...where the scope is global, routine, or blank. The default is routine.For example, the following syntax indicates that the next function should be optimized for k8_64, p7_64, andcore2_64.#pragma routine tp k8_64 p7_64 core2_64149
