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.

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.

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 

. The GNU 4.x compiler environment 

will be supported by the PathScale Compiler Suite 3.0 release.

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 .....
