I would like to start a thread about best practice for how to set up a centralized Julia installation in a cluster environment or local institution network. Hopefully, this will lead to a tutorial like write-up in the end. I want to focus on Julia 1.0 and, thus, Pkg(3). How does one set up a system…

@htwai Just tested with a clean user environment. set JULIA_PROJECT = "~/.julia/environment/v1.1 ./julia/compiled is actually created. I might not have tested with the JULIA_PROJECT env var in the previous test. Everything looks pretty good for the admin/user pattern if you put your central dep…

Here, with JULIA_PROJECT set, how does a user know which packages are available globally? Running Pkg.installed() returns nothing. Is there a way to specific to look into all depot paths?

You could temporarily switch your project to the central depot. Pkg.activate(DEPOT_PATH[2]*"/environments/v1.1") This switches, finds installed packages and then switches back to your original project: Pkg.activate(DEPOT_PATH[2]*"/environments/v1.1"); installed_pkgs = Pkg.installed(); Pkg.activate…

Here is what I contributed to the julia-in-production BoF channel at JuliaCon 2020: Hi all, I work as a computational scientist at the Swiss National Supercomputing Centre (CSCS) and am the responsible for Julia computing at CSCS. We have put Julia in September last year in production on the Piz …

[image] samo: 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 t…

First of all, we are still far from a perfect solution. Besides, like you can see looking at the never-ending discussions in Julia discourse, it is not at all obvious how an ideal solution should look like. We have opted for installing the most important packages for HPC as MPI.jl and CUDA.jl into …

Thanks Sam, that was a good overview. What happens when a new release of e.g. MPI.jl is tagged: do you need to manually go through and add that to the shared depot? Otherwise wouldn’t it install it in the user’s depot?

Sorry for the late reply. I somehow missed it. We install MPI.jl and CUDA.jl together with the Julia base module. Of course, the user can install a newer version of MPI.jl and CUDA.jl in his user space if he needs it; it will take precedence in the stacked environment. Our usual scientific softwar…
