The Hari–Zimmermann variant of the Falk–Langemeyer algorithm for the generalized SVD.

This software is a supplementary material for the paper doi:10.1016/j.parco.2015.06.004.

Only the block-oriented algorithm variants are included, up to the shared-memory thread-parallel (OpenMP) level. Distributed-memory (MPI) level is still under cleanup and will be added eventually.

HDF5

For now, the HDF5 library cannot be built with the -fdefault-integer-8 (GFortran) or -i8 (Intel Fortran) flag. Please use a pre-2.0.0 HDF5, e.g., from the tag final_autotools_develop instead. An example for configuring it on macOS (Intel):

./autogen.sh
CC=gcc-15 FC=gfortran-15 FCFLAGS="-fdefault-integer-8" CXX=g++-15 ./configure --prefix=/opt/hdf5 --enable-build-mode=production --enable-dependency-tracking --enable-fortran --enable-cxx --enable-test-express=0 --disable-doxygen-doc --enable-pic --disable-parallel --without-zlib --without-szlib
