Witryna1 Answer. Newton's method may not converge for many reasons, here are some of the most common. The Jacobian is wrong (or correct in sequential but not in parallel). The linear system is not solved or is not solved accurately enough. The Jacobian system has a singularity that the linear solver is not handling. Witryna9 maj 2016 · This answer specifically explains why the algorithm fails to converge for an input of 1e23. The issue that you're facing is known as the "small difference of large numbers" . Specifically, you're computing (x*x - y)/(2*x) where y is 1e23, and x is approximately 3.16e11.
