line options. See the PathScale compiler documentation and the man pages for
pathcc and pathf90 for complete information on its options. See the corresponding
documentation for any other compiler/linker you may call for its options.
3.5.3
To Use Another Compiler
In addition to the PathScale Compiler Suite, InfiniPath MPI supports a number of
other compilers. These include PGI 5.2 and 6.0, Intel 9.0, the GNU gcc 3.3.x, 3.4.x,
and 4.0.x compiler suites and gfortran. The IBM XL family of compilers is also
supported on ppc64 (Power) systems.
NOTE: The 2.x PathScale compilers aren’t currently supported on systems that
have the GNU 4.x compilers and compiler environment (header files and
libraries). This includes Fedora Core 4, Fedora Core 5, SUSE 10, and
SLES 10. To run on those distributions, you can compile your application
on a system that does support the PathScale compiler. Then you can run
the executable on one of the systems that uses the GNU 4.x compiler
and environment. For more information on setting up for
cross-compilation, see section 3.5.4. The GNU 4.x compiler environment
will be supported by the PathScale Compiler Suite 3.0 release.
NOTE: In addition, gfortran is not currently supported on Fedora Core 3, as it
has dependencies on the GNU 4.x suite.
The following example shows how to use gcc for compiling and linking MPI
programs in C:
$ mpicc -cc=gcc .......
To use gcc for compiling and linking C++ programs use:
$ mpicxx -CC=g++ .......
To use gcc for compiling and linking Fortran77 programs use:
$ mpif77 -fc=g77 .......
In each case, ..... stands for the remaining options to the mpicxx script, the
options to the compiler in question, and the names of the files it is to operate upon.
Using the same pattern you will see that this next example is similar, except that it
uses the PGI (pgcc) compiler for compiling and linking in C:
$ mpicc -cc=pgcc .....
To use PGI for Fortran90/Fortran95 programs, use:
$ mpif90 -f90=pgf90 .....
$ mpif95 -f95=pgf95 .....
This example uses the Intel C compiler (icc):
$ mpicc -cc=icc .....
