[Trilinos-Users] MTSGS Smoother Behavior

I am investigating some inconsistent multi-threaded behavior when using
the MueLu MTSGS smoother. When using more than one thread, we see that
no two runs of our solve code produce the same convergence behavior.

Is there anything in the MTSGS implementation that might not reproduce
the same computations each time when using more than one thread?

Thank you,
Duncan Karnitz
