With a run that completes, what's the output of a build with this flag switch to on https://github.com/Exawind/amr-wind/blob/main/cmake/set_amrex_options.cmake#L19 ?

I will be looking into this with the case files @rthedin gave me. Hopefully this week.

Some preliminary data that Jon and I were looking at: # Case: No AMR, ABL case, not very big: ``` Level 0 375 grids 12288000 cells 100 % of domain...

Ok I think I understand why "native" is not behaving the way I would expect. And I think I know why netcdf IO is using so much memory. Each rank...

Got some good news, at least on the native side: ## 4 planes, current amr-wind  ## 4 planes, https://github.com/Exawind/amr-wind/pull/1207  ## 30 planes, my branch, not possible with current...

#1209 has another round of improvements. Repeating the conclusion of that PR here: ``` - This PR removes (over 2 time steps), 3 of the 4 huge memory spikes on...

Hi, Thank you for reaching out. Improving the memory consumption of the samplers is an ongoing effort. Right now our focus is on improving the memory consumption of the native...

After #1235 I think I am going to spend time on other things and close this for now. The `native` format for samplers is now fully scalable (no bottlenecks on...

huh. That's a new one for me ;) Each user can have a max of 10^6 files total? Anyway, what's is the value of the `amr.max_grid_size` in your input file...

I am still curious about the value of that parameter. But you can control the number of files for particles (the samplers) with the input file command: `particles.particles_nfiles = 256`,...
