Use this option to turn off the debug information stripping while linking the Intel® MPI Library statically.
Use this option to source a compiler configuration file. The file should contain the environment settings to be used with the specified compiler.
Use the following naming convention for configuration files:
<install-dir>/etc/mpi<compiler>-<name>.conf
where:
Use this option to specify an MPI profiling library. <profile_name> is the name of the configuration file (profile) that loads the corresponding profiling library. The profiles are taken from <install-dir>/etc .
The Intel MPI Library comes with several predefined profiles for the Intel® Trace Collector:
<install-dir>/etc/vt.conf — regular tracing library
<install-dir>/etc/vtfs.conf — fail-safe tracing library
<install-dir>/etc/vtmc.conf — correctness checking tracing library
<install-dir>/etc/vtim.conf — load imbalance tracing library
You can also create your own profile as <profile-name>.conf. You can define the following environment variables in a configuration file:
For example, create a file myprof.conf with the following lines:
PROFILE_PRELIB="-L<path_to_myprof>/lib -lmyprof" PROFILE_INCPATHS="-I<paths_to_myprof>/include"
Use the -profile=myprof option for the relevant compiler wrapper to select this new profile.
Use the -t or -trace option to link the resulting executable file against the Intel® Trace Collector library. Using this option has the same effect as the -profile=vt option.
You can also use the I_MPI_TRACE_PROFILE environment variable to <profile_name> to specify another profiling library. For example, set I_MPI_TRACE_PROFILE to vtfs to link against the fail-safe version of the Intel Trace Collector.
To use this option, include the installation path of the Intel® Trace Collector in the VT_ROOT environment variable. Source the vars.[c]sh script provided in the Intel® Trace Analyzer and Collector installation folder.
Use the -trace-imbalance option to link the resulting executable file against the load imbalance tracing library of Intel Trace Collector. Using this option has the same effect as the -profile=vtim option.
To use this option, include the installation path of the Intel Trace Collector in the VT_ROOT environment variable. Source the vars.[c]sh script provided in the Intel® Trace Analyzer and Collector installation folder.
Use this option to link the resulting executable file against the Intel® Trace Collector correctness checking library. The default value is libVTmc.so. Using this option has the same effect as the -profile=vtmc option.
You can also use the I_MPI_CHECK_PROFILE environment variable to <profile_name> to specify another checking library.
To use this option, include the installation path of the Intel Trace Collector in the VT_ROOT environment variable. Source the vars.[c]sh script provided in the Intel® Trace Analyzer and Collector installation folder.
Use this option to enable partial ILP64 support. All integer arguments of the Intel MPI Library are treated as 64-bit values in this case.
Use this option to disable the ILP64 support explicitly. This option must be used in conjunction with -i8 option of Intel® Fortran Compiler.
If you specify the -i8 option for the separate compilation with Intel Fortran Compiler, you still have to use the i8 orilp64 option for linkage.
Use this option in combination with the -t option to link the Intel Trace Collector library dynamically. This option does not affect the default linkage method for other libraries.
To run the resulting programs, include $VT_ROOT/slib in the LD_LIBRARY_PATH environment variable.
Use this option to compile a program in debug mode and link the resulting executable file against the debugging version of the Intel MPI Library. See I_MPI_DEBUG for information on how to use additional debugging features with the -g builds.
The optimized library is linked with the -g option by default.
Use vars.{sh|csh} [debug|debug_mt] at runtime to load a particular libmpi.so configuration.
Use this option to always link the specified version of the Intel MPI Library. See the I_MPI_LINK environment variable for detailed argument descriptions. This option overrides all other options that select a specific library .
Use vars.{sh|csh}[debug|debug_mt] during runtime to load particular libmpi.so configuration.
Use this option to enable compiler optimization.
Use this option to maximize speed across the entire program. This option forces static linkage method for the Intel MPI Library.
This option is supported only by the mpiicc, mpiicpc, and mpiifort Intel® compiler wrappers.
Use this option to display everything that the command script does.
Use this option to learn how the underlying compiler is invoked, without actually running it. Use the following command to see the required compiler flags and options:
$ mpiicc -show -c test.c
Use the following command to see the required link flags, options, and libraries:
$ mpiicc -show -o a.out test.o
This option is particularly useful for determining the command line for a complex build procedure that directly uses the underlying compilers.
Use this option to see the environment settings in effect when the underlying compiler is invoked.
Use this option to select the underlying compiler. The tables below list the available LLVM and IL0 compiler options and commands used to invoke them.
| Language/Model | Product Name | Compiler Driver | Compiler Wrapper | Command | Example |
| C | Intel® oneAPI DPC++/C++ Compiler | icx | mpiicc | -cc=icx | $ mpiicc -cc=icx -c test.c |
| C++ | Intel® oneAPI DPC++/C++ C | icpx | mpiicpc | -cxx=icpx | $ mpiicpc -cxx=icpx -c test.cpp |
| SYCL*/DPC++ | Intel® oneAPI DPC++/C++ Compiler | dpcpp | mpiicpc | -cxx=dpcpp | $ mpiicpc -cxx=dpcpp -c test.cpp |
| Fortran | Intel® oneAPI Fortran Compiler | ifx | mpiifort | -fc=ifx | $ mpiifort -fc=ifx -c test. |
Use this option to disable mpiicc linking with Fortran bindings. This has the same effect as the I_MPI_FORT_BIND variable.
Use this option to print the compiler wrapper script version and its underlying compiler version.
Use this option to disable rpath for the compiler wrapper for the Intel® MPI Library.
