> 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.

Yeah julia messed this up. The basic rule is that include and using are basically the same.
