Dear Petsc experts, Another, more basic problem when using Hypre:
When I try ex2_hdf5 -f data/sphereInBlockFiner_a_cd3t.h5 -pc_type hypre -pc_hypre_type pilut -log_summary where sphereInBlock_a_cd3t.h5 contains a 102464 x 102464 matrix, the program seems to hang (it stops with the error "=>> PBS: job killed: walltime 384 exceeded limit 360"). Adding the option -ksp_max_it 1 to be sure that it is not iterating until 10000000000000 doesn't change anything. The same happens also if I use -pc_hypre_type boomeramg. It is neither the problem of my program nor of the matrix, because ex2_hdf5 -f data/sphereInBlockFiner_a_cd3t.h5 -pc_type jacobi -log_summary -ksp_rtol 0.0000000001 takes only 5s and gives me the correct solution. What do I do wrong? Looking forward to your answer, Kathrin
