For awhile I have been saying that JuliaDiffEq really needs some fast high
accuracy stiff solvers and symplectic methods to take it to the next level.
I am happy to report that these features have arived, along with some other
exciting updates. And yes, they benchmark really well. With new Rosenbrock methods
specifically designed for stiff nonlinear parabolic PDE discretizations, SSPRK
enhancements specifically for hyperbolic PDEs, and symplectic methods for Hamiltonian
systems, physics can look at these release notes with glee. Here’s the full ecosystem
release notes.
