Increased performance of tau methods

1

We need to replace some lines in the matrix with the boundary conditions in tau methods. Then we also need to replace the respective values in the right hand side...

More efficient `eval_f` in RBC on GPU

1

After profiling the code on GPUs some more, I noticed some efficiency can be gained from reducing the number of matrix multiplications. That is all that I am doing here:...

Make plot helper compatible with Python 3.13

6

Python `distutils` has been [deprecated since version 3.10 and removed in version 3.12](https://docs.python.org/3/library/distutils.html). In 3.12 I could still use it but after switching to 3.13, the plot helper was broken...

So far, we have done MPI-parallel testing in a really cumbersome way: pytest would run tests in serial, which launch a parallel execution using `subprocess`. This is slow, messy to...

Serial implementation for ParaDiag with collocation methods

3

In order to keep the PRs as short as possible, I thought now would be a good time to do the first one on ParaDiag. It is still pretty long,...

Mixed precision in pySDC

2

As GPUs get increasingly more compute power in lower precision ([down to four bits!](https://www.nvidia.com/en-us/data-center/gb200-nvl72/)) compared to double precision, we have to consider how to make efficient use of future machines...
