Examples for Linking a C Application

These examples illustrate linking of an application under the following conditions:

  • Main module is in C.
  • You are using the Intel® C++ Compiler.
  • You are using MPICH2.
  • Intel MKL functions use LP64 interfaces.
  • The PATH environment variable contains a directory with the MPI linker scripts.
  • $MKLPATH is a user-defined variable containing <mkl_directory>/lib/intel64_lin.

To link dynamically with ScaLAPACK for a cluster of systems based on the Intel® 64 architecture, use the following link line:

mpicc <user files to link>                       \
   -L$MKLPATH                                    \
   -lmkl_scalapack_lp64                          \
   -lmkl_blacs_intelmpi_lp64                     \
   -lmkl_intel_lp64                              \
   -lmkl_intel_thread -lmkl_core                 \
   -liomp5 -lpthread

To link statically with Cluster FFT for a cluster of systems based on the Intel® 64 architecture, use the following link line:

mpicc <user files to link>                \
   -Wl,--start-group                      \
   $MKLPATH/libmkl_cdft_core.a            \
   $MKLPATH/libmkl_blacs_intelmpi_lp64.a  \
   $MKLPATH/libmkl_intel_lp64.a           \
   $MKLPATH/libmkl_intel_thread.a         \
   $MKLPATH/libmkl_core.a                 \
   -Wl,--end-group                        \
   -liomp5 -lpthread

To link dynamically with Cluster Sparse Solver for a cluster of systems based on the Intel® 64 architecture, use the following link line:

mpicc <user files to link>                       \
   -L$MKLPATH                                    \
   -lmkl_blacs_intelmpi_lp64                     \
   -lmkl_intel_lp64                              \
   -lmkl_intel_thread -lmkl_core                 \
   -liomp5 -lpthread
