Linking with ScaLAPACK and Cluster FFTs on Intel Xeon Phi Coprocessors

The Intel MKL ScaLAPACK and Cluster FFTs support only Intel® MPI implementations for Intel MIC Architecture.

To link a program that calls ScaLAPACK or Cluster FFTs, you need to know how to link a message-passing interface (MPI) application first. Use MPI compiler wrappers to do this. For example, mpiicc or mpiifort are C or FORTRAN compiler wrappers, respectively, that use the correct header files and libraries. The locations of these wrappers and the MPI libraries depend on the Intel MPI version. For example, for the default installation of Intel MPI 4.1, the wrappers for the Intel MIC Architecture are /opt/impi/mic/bin/mpiicc and /opt/impi/mic/bin/mpiifort.

Check the documentation that comes with your version of Intel MPI for implementation-specific details of linking.

To link with Intel MKL ScaLAPACK and/or Cluster FFTs on Intel Xeon Phi coprocessors, use the link line shown below.

/opt/impi/mic/bin/mpi{icc|ifort} <files to link> -L<MKL path> -I<MKL include>

[-lmkl_scalapack_{lp64|ilp64}] [-lmkl_cdft_core]

-lmkl_blacs_intelmpi_{lp64|ilp64}

-lmkl_intel_{lp64|ilp64}

-lmkl_{intel_thread|sequential}

-lmkl_core

[-liomp5] [-lpthread] [-lm] [-ldl]

For example, if you are using Intel MPI 4.1, want to statically link with ScaLAPACK using the LP64 interface, and have only one MPI process per core (and thus do not use threading), specify the following linker options:

-L$MKLPATH -I$MKLINCLUDE $MKLPATH/libmkl_scalapack_lp64.a $MKLPATH/libmkl_blacs_intelmpi_lp64.a $MKLPATH/libmkl_intel_lp64.a $MKLPATH/libmkl_sequential.a $MKLPATH/libmkl_core.a -static_mpi -Wl,--end-group -lpthread -lm
