I think our hiding of plenty of useful options under --list=hidden-options is too obscure. I think we should unhide them all, printing the full options list on --help. We're being inconsistent with other projects, including hashcat, by not printing the full options list even on explicit --help. This can be confusing to new users, who wouldn't realize there are more options nor how to see tho

Current implementation of join can be improved by performing the operation in a single call to the backend kernel instead of multiple calls.

This is a fairly easy kernel and may be a good issue for someone getting to know CUDA/ArrayFire internals. Ping me if you want additional info.

As of 00e1f52cf95c16b0cea34c83372145532b4745ba the LWJGL codebase has a new directory layout. This has broken the included Eclipse project.

I often use -v just to see that something is going on, but a progress bar (enabled by default) would serve the same purpose and be more concise.

We can just factor out the code from futhark bench for this.

The TornadoVM repository contains a module with several examples. Include more use cases for acceleration with TornadoVM, such as a graphical version for NBODY, filter for photography, block-chain. etc.
