Pull request for comments about the integration of strumpack-dev into master.

  • For STRUMPACK, see: https://github.com/pghysels/STRUMPACK.
  • Look in example_build.sh and INSTALL.txt for installation instructions.
  • This branch requires metis, scotch, parmetis, ptscotch, blas, lapack, scalapack.

Test with the new Example 18p:

mpirun -np 4 ex18p -m ../data/square-disc.mesh --strumpack

It will be best if we add the --strumpack option to ex11p instead of having a separate example. Can we do that?

@pghysels, can you check the edits in the INSTALL and CHANGELOG files as well as this PR for updating the documentation? (Feel free to change anything as you see fit.)

I'd like to try to merge this today if possible. @mlstowell, @v-dobrev -- Any objections?

STRUMPACK also depends on ParMetis and Metis.
In defaults.mk STRUMPACK_LIB includes SCOTCH_LIB and SCALAPACK_LIB, but not METIS_LIB. In defaults.mk, SUPERLU_LIB also does not depend include the ParMetis library. But in defaults.cmake, ParMETIS is listed as a requirement for SuperLUDist.

In INSTALL, it says that "STRUMPACK requires the PT-Scotch and Scalapack libraries." But STRUMPACK also requires ParMetis and Metis, just like SuperLUDist.
I just want to make sure you are aware of the dependency of STRUMPACK on (Par)METIS.
