I_MPI_{CC,CXX,FC,F77,F90}_PROFILE
Specify the default profiling library.
Syntax
I_MPI_CC_PROFILE=
<profile-name>
I_MPI_CXX_PROFILE=
<profile-name>
I_MPI_FC_PROFILE=
<profile-name>
I_MPI_F77_PROFILE=
<profile-name>
I_MPI_F90_PROFILE=
<profile-name>
Argument
< profile-name > | Specify a default profiling library.
|
Description
Set this environment variable to select a specific MPI profiling library to be used by default. This has the same effect as using
-profile=
as an argument for
<profile-name>
mpiicc
or another Intel® MPI Library compiler wrapper.
I_MPI_{CC,CXX,FC,F77,F90}
Set the path/name of the underlying compiler to be used.
Syntax
I_MPI_CC=
<compiler>
I_MPI_CXX=
<compiler>
I_MPI_FC=
<compiler>
I_MPI_F77=
<compiler>
I_MPI_F90=
<compiler>
Arguments
<compiler> | Specify the full path/name of compiler to be used.
|
Description
Set this environment variable to select a specific compiler to be used. Specify the full path to the compiler if it is not located in the search path.
Some compilers may require additional command line options.
I_MPI_ROOT
Set the Intel MPI Library installation directory path.
Syntax
I_MPI_ROOT=
<path>
Arguments
<path> | Specify the installation directory of the Intel MPI Library.
|
Description
Set this environment variable to specify the installation directory of the Intel MPI Library.
If you are using the Visual Studio integration, you may need to use

Syntax
I_MPI_COMPILER_CONFIG_DIR=
<path>
Arguments
<path> | Specify the location of the compiler configuration files. The default value is
<install-dir> \ etc |
Description

Syntax
I_MPI_LINK=<
arg
>Arguments
Argument
| Library Version |
opt | Multi-threaded optimized library. This is the default value
|
dbg | Multi-threaded debug library
|
Description
