-mt_mpilink against thread-safe MPIThread-safeness up to MPI_THREAD_MULTIPLE is provided. Note that this option is implied if you build with the -openmp switch.
-check_mpilink with Intel Trace Collector MPI checking library.Prior to the invocation of the compiler and/or running the program, you need to load the special tracing module for this to work. Please see the page on ITAC for details.
-static_mpiuse static instead of dynamic MPI librariesBy default, the dynamic linkage is performed.
-t[=log]compile with MPI tracing, using Intel Trace CollectorPrior to the invocation of the compiler and/or running the program, you need to load the special tracing module for this to work. Please see the page on ITAC 'Get Started with ITAC' page for details.
-ilp64link against MPI interface with 8 byte integersyou may need to also specify -i8 for compiling Fortran code that uses default integers only.
-glink against debugging version of the MPI libraryThis will also toggle debugging mode in the compiler.
-gtool ...start selected MPI tasks under control of a toolSee the Intel documentation page on this for more details. This option should be used to perform various analysis types with MPI programs, e.g. using Inspector or VTune.
