That story is buried in a long chat thread between me and Gemini.

After all of the others were done with hacking? There was a point in time when it was giving some publicity, it is a bit late IMO.

Rust/C/C++ all have a similar memory model, they were designed for a linear memory model. a `float` does not carry the provenance (a float out of cudaMalloc or a malloc look the same to the rest of the program). This is the fundamental problem that very few (e.g., Vx vxlang.org) are trying to address.

Really like that the barrier scopes and shuffle controls are type-level, that is a lot of footguns turned into compile errors. Once you lower to PTX, does any of that structure survive for ptxas to optimize on, or is it fully erased by then? Also curious whether the strip mining abstraction fights the register allocator at higher lane counts, or if it stays friendly.

I just ask LLM to to give me a short tutorial on the thing i want to learn but i dont want to start from chapter-1, that is boring. so i upload my resume and say that make this tutorial based on the skillsets i already have.
btw, this is a much better experience than watching Youtube videos for learning.
Vx gives you the power to do so, but one can be conservative by putting all the values in the fleet/*.vx files to extreme values. An analogy to that would be when we compile for X86-64, we can specify `-mcpu` otherwise by default the compiler picks a conservative backend.
Vx allows one to define compute elements(number of cores, etc), memory elements (number of distinct memory elements, hierarchy if any) and their relationship (placement, ownership etc). Together they define the toplogoy of a machine. Toplogy goes into machine description files (see https://github.com/vx-lang/Vx/tree/main/fleet) and the compiler uses them to 'monomorphize' the program based on that topology.
