Intel® MPI Library Reference Manual for Linux* OS
I_MPI_{CC,CXX,FC,F77,F90}_PROFILE
(MPI{CC,CXX,FC,F77,F90}_PROFILE)
Specify a default profiling library.
I_MPI_{CC,CXX,FC,F77,F90}_PROFILE=<profile_name>
<profile_name> |
Specify a default profiling library. |
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 to the mpiicc or another Intel® MPI Library compiler driver.
Specify a default profile for the -trace option.
I_MPI_TRACE_PROFILE=<profile_name>
<profile_name> |
Specify a tracing profile name. The default value is vt. |
Set this environment variable to select a specific MPI profiling library to be used with the -trace option to mpiicc or another Intel® MPI Library compiler driver.
The I_MPI_{CC,CXX,F77,F90}_PROFILE environment variable overrides I_MPI_TRACE_PROFILE.
Specify a default profile for the -check_mpi option.
I_MPI_CHECK_PROFILE=<profile_name>
<profile_name> |
Specify a checking profile name. The default value is vtmc. |
Set this environment variable to select a specific MPI checking library to be used with the -check_mpi option to mpiicc or another Intel® MPI Library compiler driver.
The I_MPI_{CC,CXX,F77,F90}_PROFILE environment variable overrides the I_MPI_CHECK_PROFILE.
Turn on/off compiler compatibility check.
I_MPI_CHECK_COMPILER=<arg>
<arg> |
Binary indicator. |
enable | yes | on | 1 |
Enable checking the compiler. |
disable | no | off | 0 |
Disable checking the compiler. This is the default value. |
If I_MPI_CHECK_COMPILER is set to enable, the Intel MPI compiler drivers check the underlying compiler for compatibility. Normal compilation requires using a known version of the underlying compiler.
Set the path/name of the underlying compiler to be used.
I_MPI_{CC,CXX,FC,F77,F90}=<compiler>
MPICH_{CC,CXX,FC,F77,F90}=<compiler>
<compiler> |
Specify the full path/name of compiler to be used. |
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.
The configuration file is sourced if it exists for a specified compiler. See Configuration Files for details.
Set the Intel® MPI Library installation directory path.
I_MPI_ROOT=<path>
<path> |
Specify the installation directory of the Intel® MPI Library |
Set this environment variable to specify the installation directory of the Intel® MPI Library.
Set Intel® Trace Collector installation directory path.
VT_ROOT=<path>
<path> |
Specify the installation directory of the Intel® Trace Collector |
Set this environment variable to specify the installation directory of the Intel® Trace Collector.
Set the location of the compiler configuration files.
I_MPI_COMPILER_CONFIG_DIR=<path>
<path> |
Specify the location of the compiler configuration files. The default value is <installdir>/<arch>/etc |
Set this environment variable to change the default location of the compiler configuration files.
Select a specific version of the Intel® MPI Library for linking.
I_MPI_LINK=<arg>
<arg> |
Version of library |
opt |
The optimized, single threaded version of the Intel® MPI Library |
opt_mt |
The optimized, multithreaded version of the Intel MPI Library |
dbg |
The debugging, single threaded version of the Intel MPI Library |
dbg_mt |
The debugging, multithreaded version of Intel MPI Library |
Set this variable to always link against the specified version of the Intel® MPI Library.
Turn on/off the debug information stripping while linking applications statically.
I_MPI_DEBUG_INFO_STRIP=<arg>
<arg> |
Binary indicator |
enable | yes | on | 1 |
Turn on. This is the default value |
disable | no | off | 0 |
Turn off |
Use this option to turn on/off the debug information stripping while linking the Intel® MPI Library statically. Debug information is stripped by default.
