Sharpero

This is an implementation of an Interpreter/Compiler for the Prospero challenge, implementing some basic optimizations including removing constants from the instruction tape, vectorization, parallelization but also optionally compiling the loop of the evaluator to CIL prior to invocation.

It doesn't perform any sophisticated interval-arithmetic based optimizations (... yet), it's essentially a brute-force approach.

This program is also an interactive visualizer of the rendering process, allowing you to see exactly how it's writing the image data out, and toggle vectorization, parallel execution, compilation on/off and observe the effects on runtime.

(Crude) Benchmark Results

On my own machine (CPU: Ryzen 7 4800HS), the results tabulate roughly as follows.

Compilation Parallelism Vectorization Evaluation Time Compilation Time
enabled enabled enabled 0.2s 0.2s
enabled enabled disabled 1.3s 0.2s
enabled disabled enabled 1.7s 0.2s
enabled disabled disabled 10s 0.2s

Recommendations

Probably don't use this with some kind of agentic LLM workflow, bad things might happen :) Don't say I didn't warn you.
