4    happy breakdown tolerance 1e-30
5  maximum iterations=10000, initial guess is zero
6  tolerances:  relative=1e-05, absolute=1e-50, divergence=10000.
7  left preconditioning
8  using PRECONDITIONED norm type for convergence test
9PC Object: 1 MPI processes
10  type: asm
11    total subdomain blocks = 1, amount of overlap = 1
