[petsc-users] KspTrueResidualNorm

Dear all,

I'm using Ksp *gmres* with *boomeramg* preconditioning and I suspect that
even though it converges in preconditioned norm it doesn't converge in true
norm, but as I understand *KSPSetNormType* gmres does not support true
residual norm? Is that correct and If it is, is there any other way to
monitor the true norm? Do I need to Introduce my own convergence test?

Best,
A. Mesgarnejad
