MCHPRS

Pretty cool. The program itself was written in an existing intermediate language called URCL, which was then compiled to CHUNGUS2 assembly. CHUNGUS2 is the processor made with Minecraft's redstone mechanics. The processor was emulated for development, but the demo is running on MCHPRS, a Minecraft server that uses Wasmtime's Cranelift to JIT the redstone operations, which are represented as a weighted directed graph. Before MCHPRS, optimizing redstone performance using compiler techniques was not thought to be possible. With MCHPRS the demo takes 9 hours to run, it would take decades using Minecraft. https://github.com/sammyuri/minecraft https://github.com/MCHPR/MCHPRS As for CHUNGUS2 itself, it's a proper RISC processor, it has a 4-stage instruction pipeline, 64 byte 8-way associative data cache, even branch prediction. https://www.youtu

It's mind blowing how much effort they put into this, the MCHPRS server even JIT compiles redstone into native code using Cranelift: https://github.com/MCHPR/MCHPRS/blob/master/docs/Redpiler.md It really saddens me that their post was removed from r/Minecraft, for crediting a server by including its IP address for literally one second in the video.

As explained in the description of the video, this is not running on a vanilla Minecraft server, but on their own implementation optimized to run redstone circuits. The code displayed at the beginning seems to come from that: https://github.com/MCHPR/MCHPRS/blob/master/crates/core/src/...
