gateau 0.2.0

GPU-Accelerated Time-dEpendent observAtion simUlator

Welcome to the gateau Github repository: the GPU-Accelerated Time-dEpendent observAtion simUlator! This is the end-to-end simulator for TIFUUn observations, and is currently still in progress. For more info, please see the documentation pages (to be fixed).

Installation

Installing CUDA

CUDA is an API, developed by NVIDIA, to harness the computing power of a graphics processing unit (GPU) for general purpose computing. It provides access to the GPU's instruction set through common high-level programming languages, such as C and C++.

gateau uses CUDA for calculations, and hence must be installed in order to use gateau. It can be installed from source or using a package manager. gateau has been tested on both CUDA version 11 and 12, so please stick to these versions. Error-free performance on other versions is NOT guaranteed.

Even though gateau was exclusively developed on a GTX 1650 Mobile, which is nowhere near impressive by today's standards, it is probably a good idea to use gateau on GPU's that meet or exceed the specs of this particular card.

Installing gateau

Gateau is available from pypi. You can install it like any other python package:

pip install gateau

The installation can be verified by opening a terminal, starting the python interpreter (make sure you are in the environment where gateau is installed), and running the following:

import gateau
gateau.selftest()

When installed correctly, the test should run without issues.

Supported Platforms

We currently only support Linux with GNU libc (known as manylinux in the Python world). We do not ship wheels for other operating systems or linuxes with other libc implementations. If you want to get gateau working on one of these platforms, have a read of MAINTAINERS.md (and please let us know if you're interested in helping us get gateau running on other platforms!).

For maintainers and developers

For information on things like running tests and making new releases of Gateau, please consult MAINTAINERS.md. For contribution guidelines, see CONTRIBUTING.md
