VexParallelism-First Systems Programming

Every Cycle, Every Core, Every Time

Get Started

Architecture

CLI Reference

LLVM 21 Toolchain

Native codegen is built around LLVM 21.1.8 with JIT and no-JIT execution paths.

Memory-Safe Systems Model

Ownership, borrowing, NLL-style analysis, and VUMM-backed heap management without GC.

SIMD, Tensor, and SIR

Arrays, tensors, masks, fusion, and backend lowering to SIMD, SPIR-V, WGSL, and Metal.

Concurrency Built In

go blocks, async workflows, channels, and a runtime scheduler designed for real workloads.

Typed Low-Level Access

Ptr, Span, RawBuf, FFI, and freestanding workflows for systems code.

Full Tooling Loop

vex run, vex compile, vex test, diagnostics, formatter, docs tooling, and editor support.

Documentation Map

Guide: language model, syntax, ownership, concurrency, SIMD/SIR, and tooling.
Architecture: compiler pipeline, crate layout, and where major subsystems live.
Reference: command-level and toolchain-level behavior for CLI, test runner, docs, and package management.

What This Site Covers

This documentation focuses on the Vex language, compiler model, execution pipeline, and developer workflows. Standard library module references live under /std/, but the main guide is where language semantics, memory model, concurrency, SIMD/SIR, and error handling are explained.

Suggested Path

Start with Introduction.
Set up the toolchain with Installation.
Learn the core language in Syntax, Functions, and Control Flow.
Move to Enums, Ownership, and Error Handling.
Finish with SIMD, GPU & SIR, and Testing.
