With this you are likely at a point where factorizations (even ILU)
not work very well. Even if you can afford a Block ILU, you likely run
on 100+ cores, which means the quality of the preconditioner

I suspect that in that case, it wouldn't be cheaper to loop over particles and
map back to particles, but that you could as well loop over pa

In this case, even using ILU(1) is extremely expensive (e.g. it takes 2X more
time than to assemble the matrix and it really doubles up the iteration time).
Consequently, we are using ILU(0), which in the present case is performing
relatively wel

Hello all,
I hope you are all well. This is not strictly a deal.II question, but I
thought I could benefit for the huge amount of expertise present on this
board.
I am currently launching large (at least from my POV) tasks on our HPC
cluster. The task generally contain on the order of 50M to 10
