Irrespective of how you install Julia, before executing Julia in a new environment (such as on a computing node), you first need load it, depending on the istallation via (via module load julia<\/span> or executing the lines above).<\/p>\n

To check the whether everything is as you would expect, you can start the Julia REPL (typing julia<\/span>) and print the following:<\/p>\n
