Compilation Environment Variables
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=<profile-name> as an argument for 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.
NOTE:
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.
NOTE:
If you are using the Visual Studio integration, you may need to use I_MPI_ONEAPI_ROOT.
VT_ROOT
Set Intel® Trace Collector installation directory path.
Syntax
VT_ROOT=<path>
Arguments
| <path> | Specify the installation directory of the Intel Trace Collector. |
Description
Set this environment variable to specify the installation directory of the Intel Trace Collector.
NOTE:
Intel Trace Analyzer and Collector 2022.3 is the final version. No further feature improvements or security fixes will be available after this final release. For more information, see the Intel Trace Analyzer and Collector transition notice.
I_MPI_COMPILER_CONFIG_DIR
Set the location of the compiler configuration files.
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
Set this environment variable to change the default location of the compiler configuration files.
I_MPI_LINK
Select a specific version of the Intel MPI Library for linking.
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
Set this variable to always link against the specified version of the Intel MPI Library.
I_MPI_MSVC_VERSION
Specify the version of the Microsoft* Visual Studio to be used.
Syntax
I_MPI_MSVC_VERSION=<version>
Argument
| <version> | Specify the numeric full-version number of Microsoft* Visual Studio. |
Description
Set this environment variable to select a specific Microsoft* Visual Studio version to be used by C/C++ compiler wrapper, such as mpicc, mpiicc, mpiicpc, mpicxx, and mpiicx.
By default, the latest available version is used.
