Quick start

warning

This version of ZLUDA is under heavy development and will likely not work with your application yet. In the meantime, you are encouraged to try it and report results.

How to get it

ZLUDA evolves quickly, we recommend downloading the most recent pre-release version. Periodically, we mark a pre-release version as stable, you can download it from the "Releases" section on our Github page.

Usage

Windows

You should have a recent AMD GPU driver ("AMD Software: Adrenalin Edition") installed.
To run your application either:

(Recommended) Copy all ZLUDA files (including nvcuda.dll) from zluda (if you downloaded a zip package) or target\release (if you built from sources) into a path which your application uses to load CUDA. Paths vary application to application, but usually it's the directory where the .exe file is located
Use ZLUDA launcher:
```
<ZLUDA_DIRECTORY>\zluda_with.exe -- <APPLICATION> <APPLICATION_ARGUMENTS>
```
ZLUDA launcher is known to be buggy and incomplete, but it's less invasive

Linux

Run your application like this:

Recommended method
```
LD_LIBRARY_PATH="<ZLUDA_DIRECTORY>:$LD_LIBRARY_PATH" <APPLICATION> <APPLICATION_ARGUMENTS>
```
where <ZLUDA_DIRECTORY> is the directory which contains ZLUDA-provided libcuda.so: zluda if you downloaded a prebuilt package or target/release if you built from sources.
Alternative method
```
LD_PRELOAD="<ZLUDA_DIRECTORY>/zluda_preload" <APPLICATION> <APPLICATION_ARGUMENTS>
```
where <ZLUDA_DIRECTORY> is the directory which contains ZLUDA-provided libcuda.so: zluda if you downloaded a prebuilt package or target/release if you built from sources.
