Compilers Support

Intel® MPI Library supports the GCC* and Intel® compilers out of the box. It uses binding libraries to provide support for different
glibc
versions and different compilers. These libraries provide C++, Fortran 77, Fortran 90, and Fortran 2008 interfaces.
The following binding libraries are used for GCC* and Intel® compilers:
  • libmpicxx.{a|so}
    — for
    g++
    version 3.4 or higher
  • libmpifort.{a|so}
    — for
    g77
    /
    gfortran
    interface for GCC and Intel® compilers
Your application gets linked against the correct GCC* and Intel® compilers binding libraries, if you use one of the following compiler wrappers:
mpicc
,
mpicxx
,
mpifc
,
mpif77
,
mpif90
,
mpigcc
,
mpigxx
,
mpiicc
,
mpiicpc
, or
mpiifort
.
For other compilers, PGI* and Absoft* in particular, there is a binding kit that allows you to add support for a certain compiler to the Intel® MPI Library. This binding kit provides all the necessary source files, convenience scripts, and instructions you need, and is located in the
<install_dir>/binding
directory.
To add support for the PGI* C, PGI* Fortran 77, Absoft* Fortran 77 compilers, you need to manually create the appropriate wrapper script (see instructions in the binding kit
Readme
). When using these compilers, keep in mind the following limitations:
  • Your PGI* compiled source files must not transfer
    long double
    entities
  • Your Absoft* based build procedure must use the
    -g77
    ,
    -B108
    compiler options
To add support for the PGI* C++, PGI* Fortran 95, Absoft* Fortran 95, and GNU* Fortran 95 (4.0 and newer) compilers, you need to build extra binding libraries. Refer to the binding kit
Readme
for detailed instructions.
