Compilation Command Options

-profile=
<profile_name>
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
<installdir>\
etc
.
You can create your own profile as
<installdir>\etc\<profile_name>.conf
. You can define the following environment variables in a configuration file:
  • PROFILE_PRELIB
    - libraries (and paths) to load before the Intel® MPI Library
  • PROFILE_POSTLIB
    - libraries to load after the Intel® MPI Library
  • PROFILE_INCPATHS
    - C preprocessor arguments for any include files
For example, create a file
<installdir>\etc
\myprof.conf
with the following lines:
SET PROFILE_PRELIB=
<path_to_myprof>
\lib\myprof.lib SET PROFILE_INCPATHS=-I"
<paths_to_myprof>
\include"
Use the
-profile=myprof
option for the relevant compiler wrapper to select this new profile.
-t or -trace
Use the
-t
or
-trace
option to link the resulting executable file against the Intel® Trace Collector library.
To use this option, include the installation path of the Intel® Trace Collector in the
VT_ROOT
environment variable. Source the
vars.bat
script provided in the Intel® Trace Analyzer and Collector installation folder.
-check_mpi
Use this option to link the resulting executable file against the Intel® Trace Collector correctness checking library. The default value is
libVTmc.so
.
To use this option, include the installation path of the Intel® Trace Collector in the
VT_ROOT
environment variable. Source the
vars.
bat
script provided in the Intel® Trace Analyzer and Collector installation folder.
-ilp64
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.
-no_ilp64
Use this option to disable the ILP64 support explicitly. This option must be used in conjunction with
-i8
option of Intel® Fortran Compiler.
Note
If you specify the
-i8
option for the Intel® Fortran Compiler, you still have to use the
ilp64
option for linkage.
-link_mpi=<
arg
>
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, such as
-Zi
.
/Zi, /Z7 or /ZI
Use these options to compile a program in debug mode and link the resulting executable against the debugging version of the Intel® MPI Library. See
I_MPI_DEBUG
for information on how to use additional debugging features with the
/Zi
,
/Z7
,
/ZI
or
debug
builds.
Note
The
/ZI
option is only valid for C/C++ compiler.
-O
Use this option to enable compiler optimization.
Setting this option triggers a call to the
libirc
library. Many of those library routines are more highly optimized for Intel microprocessors than for non-Intel microprocessors.
-echo
Use this option to display everything that the command script does.
-show
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:
This option is particularly useful for determining the command line for a complex build procedure that directly uses the underlying compilers.
-show_env
Use this option to see the environment settings in effect when the underlying compiler is invoked.
-{cc, cxx, fc}=<
compiler>
Use this option to select the underlying compiler.
For example, use the following command to select the Intel® C++ Compiler:
> mpiicc -cc=icl.exe -c test.c
For this to work,
icl.exe
should be in your
PATH
. Alternatively, you can specify the full path to the compiler.
Note
This option works only with the
mpiicc.bat
and the
mpifc.bat
commands.
-v
Use this option to print the compiler wrapper script version.
-norpath
Use this option to disable rpath for the compiler wrapper for the Intel® MPI Library.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
