Selecting a Library Configuration

You can specify a particular configuration of the Intel® MPI Library to be used, depending on your purposes. This can be a library optimized for multi-threading debug or release version with the global lock.
To specify the configuration,
run the
vars.bat
file
with the
-i_mpi_library_kind
environment variable and the release, or
debug
argument. For example:  
> <install-dir>\env\vars.bat -i_mpi_library_kind=release
-i_mpi_library_kind
environment variable sets the library configuration. See the for details.
You can use the following arguments:
Argument
Definition
release
Set this argument to use multi-threaded optimized library (with the global lock). This is the default value
debug
Set this argument to use multi-threaded debug library (with the global lock)
You do not need to recompile the application to change the configuration.
Run the
vars.bat
file
with appropriate arguments before an application launch.
If you want to enable or disable usage of libfabric* from the Intel MPI Library, set the
-i_mpi_ofi_internal
environment variable. See the for details.
