[petsc-users] KSPConvergedReason = KSP_CONVERGED_ITERATING

[Chung-Kan Huang]

Hi,

I am encountering KSPSolve hanging with one process finished
KSPSolve reporting KSPConvergedReason = KSP_CONVERGED_ITERATING while other
processes stuck in KSPSolve.

The problem is not seen when code was compiled in debug mode and problem
only appears after more than 10 hours of run time with production mode.

Can anyone suggest how I can do to debug this case?

Thanks,

Ken
