vkdispatch-core 0.0.32

A Python module for orchestrating and dispatching large computations across multi-GPU systems using Vulkan.

Getting Started

Welcome to vkdispatch! This guide will help you install the library and run your first GPU-accelerated code.

[WARNING: The documentation is still under heavy development, and has many missing sections]

Note: vkdispatch requires a Vulkan-compatible GPU and drivers installed on your system. Please ensure your system meets these requirements before proceeding.

Installation

The default installation method for vkdispatch is through PyPI (pip):

# Install the package
pip install vkdispatch

On mainstream platforms — Windows (x86_64), macOS (x86_64 and Apple Silicon/arm64), and Linux (x86_64) — pip will download a prebuilt wheel (built with cibuildwheel on GitHub Actions and tagged as manylinux where applicable), so no compiler is needed.

On less common platforms (e.g., non-Apple ARM or other niche architectures), pip may fall back to a source build, which takes a few minutes. See Building From Source for toolchain requirements and developer-oriented instructions.

Tip: If you see output like Building wheel for vkdispatch (pyproject.toml), you’re compiling from source.

Verifying Your Installation

To ensure vkdispatch is installed correctly and can detect your GPU, run:

# Quick device listing
vdlist

# If the above command is unavailable, try:
python3 -m vkdispatch

If the installation was successful, you should see output listing your GPU(s), for example:
