Info in the documentation about the importance of JULIA_DEPOT_PATH

[glwagner]

ClimaOcean uses Scratch.jl to save big datasets like ECCO and JRA55 at JULIA_DEPOT_PATH (which by default is ~/.julia. This means that on clusters, it's important to change JULIA_DEPOT_PATH environment variable to a location that has a lot of storage; often this is different from the default choice. We should document this, probably in a section "setting up ClimaOcean on clusters" in the documentation or something.

It’s important to change that anyway regardless of ClimaOcean. Eg on the Australian HPC there is a 10GB limit in home directory so the .julia dir would fill that up even before Scratch.jl.

That's fair; that's also why its ok to use the depot in the first place for scratch, since changing the depot path to a place that can hold lots of data is more generally important.
