[deal.II] Preconditioner for asymmetric matrix-free style matrix

Hi all, As described in the title, I am looking for an appropriate preconditioner for an asymmetric matrix implemented in matrix-free style. I've gone though all the matrix-free tutorials and none of them talks about the asymmetric case. (Almost all of them use the Chebyshev smoother with

Re: [deal.II] Re: Do docker container support cuda

Hi Bruno, Thanks for the reply. It would be great if you could do me the favor. Since I'm still trying to master the library, not sure if extra parallel computation library is needed besides *hdf5 and boost* for output and toolkits. To my knowledge, dealii image is built from source based on the

[deal.II] Do docker container support cuda

Hi all, My team and I got two nvidia GPUs recently so we think we might use them for program acceleration. We use the dealii container as our dev env and to keep its strength, we use *nvidia-docker2 *to provide a runtime cuda support within containers. The command *nvidia-smi* shows the
