[deal.II] Re: Status of hybrid shared/distributed parallelism

Lucas, Why are you interested in hybrid parallelism? Are you hoping to improve the performance of your code or is it simply something you want to try? If the solver is the bottleneck in your code, you should focus on finding a better preconditioner. With that being said, matrix-free methods ten

[deal.II] Status of hybrid shared/distributed parallelism

Hi folks, I'm wondering if there's somewhere I can look to get a broad overview of the different parallelization schemes available in deal.II for various pieces of the library, and maybe what people's experiences have been. As I understand it, any matrix/vector assembly can be done with a shar

[deal.II] Step-51 shows instability when implemented with IPHDG and DGQ spaces

Hi there, I have recently implemented a hybridizable discontinuous Galerkin method for the convection-diffusion equation adapted from step-51. Instead of the LHDG method used therein, I used IPHDG. Some major differences between the two include that IPHDG doesn't have a vector-valued auxiliar

[deal.II] reference for citing the concept of vector-valued test functions?

Dear all, is the deal.ii implementation of vector-valued test functions as described here also described in an article, paper, ... or is this a "deal.ii thing"? I would like to make a reference in a publication where
