Languages & Libraries Similar to GLSL’s “multi-main” Execution

This list focuses on environments where an entry function is executed in parallel across many elements (pixels, vertices, work-items, indices).

Shader Languages — Parallel execution on GPU

HLSL (High-Level Shading Language)

Developed by Microsoft for Direct3D. Like GLSL, per-pixel/vertex (and compute) entry points are run in parallel on the GPU.

Python-based DSLs — Parallel-first approach

Taichi

An embedded DSL for Python; functions marked with @ti.kernel are JIT-compiled and executed in parallel on CPU/GPU backends.

Quick Reference

Category	Name	Parallel-execution gist
Shader language	HLSL	Per-fragment/vertex/compute entry points run concurrently across many GPU threads.
Python DSL	Taichi	Index-wise kernels mapped to massive parallelism on GPU/CPU via JIT compilation.
