Working with Intel® MathKernel Library Cluster9SoftwareThis chapter discusses usage of Intel® MKL ScaLAPACK and Cluster FFTs, mainlydescribing linking your application with these domains and including C- and Fortran-specificlinking examples; gives information on the supported MPI.See Table 3-7 for detailed Intel MKL directory structure in chapter 3.For information on the available documentation and the doc directory, see Table 3-8 in thesame chapter.For information on MP LINPACK Benchmark for Clusters, see section Intel® Optimized MPLINPACK Benchmark for Clusters in chapter 10.Intel MKL ScaLAPACK and FFTs support MPICH-1.2.x and Intel® MPI.To link a program that calls ScaLAPACK, you need to know how to link an MPI applicationfirst.Typically, this involves using mpi scripts mpicc or mpif77 (C or FORTRAN 77 scripts) thatuse the correct MPI header files and others. If, for instance, you are using MPICH installedin /opt/mpich, then typically /opt/mpich/bin/mpicc and /opt/mpich/bin/mpif77 willbe the compiler scripts and /opt/mpich/lib/libmpich.a will be the library used for thatinstallation.Linking with ScaLAPACK and Cluster FFTsTo link to ScaLAPACK and/or Cluster FFTs in Intel MKL, use the following general form: \-L \ \where is one of several MPI implementations (MPICH, Intel MPI 1.x, Intel MPI 2.x,Intel MPI 3.x)9-1
