5–Using QLogic MPI

To Use Another Compiler
QLogic MPI supports a number of compilers, in addition to the default GNU
Compiler Collection (GCC) versions 3.3.x, 3.4.x, 4.0, and 4.1 and gfortran. These
include the PathScale Compiler Suite 3.0 and 3.1; PGI 5.2, 6.0, and 7.1; and Intel
9.x and 10.1.
These compilers can be invoked on the command line by passing options to the
wrapper scripts. Command line options override environment variables, if set.
The following tables show the options for each of the compilers.
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 upon which it
operates.
NOTE:
The GNU 4.x environment is supported in the PathScale Compiler Suite 3.x
release. However, the 2.x PathScale compilers are not currently supported
on SLES 10 systems that use the GNU 4.x compilers and compiler
environment (header files and libraries). QLogic recommends installing the
PathScale 3.1 release.
