How does one set up a centralized Julia installation?

Then, this works all pretty well for small or medium jobs, but for large jobs with thousands of GPUS it is not good that each process needs to read from the same files (stacked environment / home). For large-scale deployment, it would be nice if one could create a binary / folder that can be copied at the beginning of a job to the compute nodes ram-disk (/tmp) and then each compute node just reads from there during the job.

I agree. We should not assume that /home/user/.julia is the place where Julia keeps software.
As @samo points out this does not scale on big HPC systems - I have worked with systems where /home is deliberatley quotaed very small.

But why do you not then use JULIA_PROJECT and JULIA_DEPOT_PATH which are located on a fast filessystem? Clearly I am about to be schooled here…
