I'm having a problem with GAMG causing a MatSetValues() is [some non-zero number] after
[0] PCSetUp(): Setting up new PC I don't get this with either ILU or HYPRE/BoomerAMG. I've attached the output of -info. I see there is a recent change to some pre-allocation for GAMG here: http://petsc.cs.iit.edu/petsc/petsc-dev/rev/fe806009181b I'm not sure if that has anything to do with it, but my blocksize is 1. I'm running with the following options. -ksp_type bcgsl -pc_type gamg -pc_gamg_threshold 0.01 -mg_levels_ksp_type richardson -mg_levels_pc_type sor -mg_coarse_ksp_type richardson -mg_coarse_pc_type sor -mg_coarse_pc_sor_its 4 -pc_gamg_type agg -pc_gamg_agg_nsmooths 1 -pc_gamg_sym_graph true -info -ksp_monitor_true_residual Thanks, John -------------- next part -------------- An HTML attachment was scrubbed...
