Dear all, Yesterday I came across SymRCM.jl package, which seems to work really neatly and is easy to use, but it doesn’t seem to bring me any performance benefits. Allow me to explain. I wrote a little computational fluid dynamics program in Julia, and this is how the system matrix looks after d…

SymRCM doesn't seem to help linear solver to perform

OK, but then there is little merit in renumbering. Iterative solvers don’t care.
