> How do you develop a program which will run for longer duration on HPCs. The main strategy is to have a way of parameterize the program to bring the runtime down to seconds-minutes on a laptop. E.G. for PDEs, you may be running the HPC version on a giant mesh, but you can run the same algorithm on your local computer on a much coarser mesh. > How do you quickly modify struct definitations Thankfully on 1.12 this has been solved. You can redefine structs while keeping the REPL up. > how do you define imports (using vs include syntax is so confusing!) Yeah julia messed this up. The basic rule is that include and using are basically the same.
