mpb (computes electromagnetic band structures and modes) MPB is a free and open-source software package for computing electromagnetic band structures and modes. It saves results in hdf5 format. This package requires: hdf5, libctl, lapack You may wish to also install: h5utils You very probably want to build a multi-processor version of this code by adding the "--with-openmp" configure option. Configuration: If the build script can find the ATLAS libraries, it will adapt the configure options to use them rather than the default lapack. You can add additional options to the command line using the environment variable SBOPTIONS_MPB; e.g. to enable MPI (multi-processor calculation) using openmp, use: SBOPTIONS_MPB="--with-openmp" ./mpb.Slackbuild Alternatively, if building non-interactively (e.g. if using slpkg), use/create the file /etc/sbo_pkg_options.conf since this slackbuild script will search it for options. Simply include a line starting "mpb:" followed by options, e.g.: mpb: --with-openmp If you want to use mpich instead of openmp, you will have to recompile the installed slackware fftw library with two additional configure options, i.e. not only "--with-mpi" but also "--enable-type-prefix". Note: This mpb build script does *two* passes. This is so that when MPI support is enabled, the first compiles the mpb-data utility, then the second builds the full MPI version. The resulting package includes both, with any MPI version of the files replacing the non- MPI version.
