Hi all, When exactly would one need to modify the default restart value of 30 for GMRES? I have seen papers like this <http://computation.llnl.gov/projects/hypre-scalable-linear-solvers-multigrid-methods/Baker-2009-GMRES.pdf> which suggest playing around with values between 1 and 30, but are there cases where people need to use large restart values like 50 or 100?
Thanks, Justin
