Repository files navigation

  • Both the source files and header files are in src.
  • The directory data contains sample matrices and vectors.
  • Rough two-level and multilevel preconditioners. Each has own PCG solver, which is perhaps not ideal.
  • Slightly altered Caitlin's partition.hpp file.
  • Note: METIS does not like nparts = 1.
  • Use the standard CMake procedure: mkdir build && cd build && cmake ..
  • Todo: allow for different smoothers.
