Hey now, we're not sadists. ;-) First configure PETSc with --download-superlu_dist or --download-mumps (or install these packages yourself and use --with-superlu_dist-dir=, see the output from ./configure --help for details). Then just run your program with -pc_type lu -pc_factor_mat_solver_type superlu_dist, no need to modify any code. -------------- next part -------------- An HTML attachment was scrubbed...
