Hi @dpgrote, do you have any feedback on this PR and/or the last comment https://github.com/BLAST-WarpX/warpx/pull/6053#issuecomment-3255569948 in particular?

> As for the big checksum change, I think the difference starting from roundoff can get amplified a lot because the solver is iterative. I think part of what seems...

@oshapoval There are some conflicts that need to be resolved, otherwise the pre-commit CI check cannot run properly.

I have no objections to the fix per se, but isn't this (a tridiagonal matrix algorithm) something basic enough to belong better to a numerical library like AMReX rather than...

@JustinRayAngus Some info on the CI configuration topic. This is the step where we configure and compile WarpX before running the CI tests in the Azure pipelines: https://github.com/BLAST-WarpX/warpx/blob/83cfdd028a5aba612f1d03cb0cf22c432f0f98b8/.azure-pipelines.yml#L142-L158 You see...

Found this old PR and just merged `development` in to see if we can finalize it easily.

FYI, still struggling to "fix" this: ```console /home/runner/work/WarpX/WarpX/Source/Utils/ParticleUtils.H:36: error: no matching file member found for amrex::DenseBins< ParticleTileDataType > ParticleUtils::findParticlesInEachCell(int lev, const amrex::MFIter &mfi, WarpXParticleContainer::ParticleTileType &ptile) Possible candidates: 'amrex::DenseBins< ParticleTileDataType >...

I'd be happy to finalize this, unfortunately when I tried in December I ran into the weird "error" (which seems to me like a false positive) described in https://github.com/ECP-WarpX/WarpX/pull/3560#issuecomment-2524786622 above,...
