Okay but how do you distribute the program that depends on Julia to clients? You then also need to ensure that they have the right Julia available on their system. That's much heavier than dynamic binaries (which rely only on some shared libraries). My point was that it's not always "easy" to call Julia. That it's easy in HPC is a reasonable statement since you probably have full control over the system and it has loads of RAM available, but I wouldn't call it easy in general.

I guess we're both right. I was talking about the "libraries" functionality [1].
