Architecture-aware $h$-to-$p$ optimisation: spectral/$hp$ element operators for mixed-element meshes
Architecture-aware optimizations for spectral/hp operators on mixed-element meshes achieve Helmholtz throughput on tetrahedra within 2.5 times that of hexahedra despite six times more floating-point operations.
