-ksp_pipelcg_pipel | - pipelined length | |
-ksp_pipelcg_lmin | - approximation to the smallest eigenvalue of the preconditioned operator (default: 0.0) | |
-ksp_pipelcg_lmax | - approximation to the largest eigenvalue of the preconditioned operator (default: 0.0) | |
-ksp_pipelcg_monitor | - output where/why the method restarts when a sqrt breakdown occurs | |
