When does a fluids mini-app cease to be "mini"? What separates Colorful Fluid Dynamics (CFD; h/t @kpdooty) from a tool for science?

I'd argue it's when you collect turbulent statistics and get careful about statistical convergence. Our fluids mini-app was created to drive #libCEED and #PETSc library integration, but has now taken this step as it transforms into an instrument to explain how RANS models fail (and what they need to succeed). With a 10x strong scaling boost so far.

#HPC

#libCEED 0.11 was released last week, providing performance-portable element algebra designed for integration in your code. These data structures move your sparse linear algebra from the dotted line to the solid line, giving a 2x performance boost even for lowest order elements (solid and fluid mechanics). This release has memory checking, backend and H(div) improvements, and various utilities, plus lots of new features in the implicit compressible viscous flow solver.

@tgamblin @danibanez Indeed! We also have #libCEED and (partial) #PETSc bindings. @TimoBetcke is also working on Rust for scientific computing/linear algebra. And you might be interested in conversations at https://rust-scicomp.zulipchat.com/
