Running with 2 threads is the worst memory-wise.

See benchmarks from #1120 (comment) and similar results were reported by @francispoulin on a different machine from #1210 (comment)

Not sure if this is because of Oceananigans.jl or because of KernelAbstractions.jl

Multithreaded seems to allocate a ton of memory in general though.

I'm closing this issue because I'm judging that it's not of current, timely relevance to Oceananigans development. If you would like to make it a higher priority or if you think the issue was closed in error please feel free to re-open.
