MPI

OpenMP

pika

pika provides a CMake config script in $pika_ROOT/lib/cmake/pika. To make it available, the variable pika_DIR has to be set to this path. Depending on the platform, the files may also be in lib64 instead of lib.

e.g. cmake -Dpika_DIR=${PIKA_ROOT}/lib/cmake/pika ..

BLAS/LAPACK

BLAS/LAPACK can be provided by:

  • Compiler
  • Custom
  • MKL

Former two options are available if DLAF_WITH_MKL=off, allowing through LAPACK_TYPE to choose between:

  • Compiler: choose this if a compiler wrapper that internally manages linking to BLAS/LAPACK is available
  • Custom: choose this if you want to manually specify LAPACK_INCLUDE_DIR and LAPACK_LIBRARY

In particular:

  • LAPACK_INCLUDE_DIR: a ;-list of include paths (without -I option)
  • LAPACK_LIBRARY: a ;-list of
    • library names (e.g. BLAS)
    • library filepaths (e.g. /usr/local/lib/libblas.so)
    • -L<library_folder> (e.g. -L/usr/local/lib)

Otherwise, with DLAF_WITH_MKL=on it looks for BLAS/LAPACK provided by MKL. It uses MKLROOT environment variable if set or MKL_ROOT CMake variable (which has priority if both are set).

MKL is fixed to "Sequential" and does not use threading.

BLASPP & LAPACKPP

BLASPP and LAPACKPP dependencies can be satisfied by specifying installation directories into blaspp_DIR and lapackpp_DIR variables, respectively.
