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.
