Release of v5.3.0

COMPASS v5.3.0 release notes :

  • New feature: User-defined phase screens circular buffer in the telescope. Allows to put a cube of phase screens as an additional input of the telescope.
  • New feature: Field stop can now be used with SHWFS. Does not simulate flux reduction.
  • Modification of the custom DM construction: see the new tutorial dedicated to this topic
  • Support for clang compiler
  • Fix a bug of the KL basis computation due to the move from MAGMA to CUSOLVER library
  • Minor fixes

Plan for COMPASS

We want to share with you our view of COMPASS roadmap after today’s release of v5.1.0. If COMPASS is efficient as of today, we also want to make it easier to use and to contribute for. We are aware of the current software architecture may be a bit complex with all those layers (Python, C++, CUDA) : we are looking for the API provided by NVIDIA and third party libraries like CuPy to simplify the code, and maybe converging into a full Python stack while keeping the performance as high as today and even better.

Just for information, COMPASS can run under WSL. follow this tutorial: CUDA on WSL :: CUDA Toolkit Documentation Some important points: you must register in the Microsoft Windows Insider Program in the dev channel in order to have a build version 20145 or higher Install the nvidia CUDA on WSL driver Install the cuda-toolkit-11-1 instead of the cuda-toolkit-11-0 Do not choose the cuda, cuda-11-1, or cuda-drivers meta-packages under WSL 2 Afterwards, it’s quite easy.

Release of v5.0.0

The goal of this release is to improve the code quality. This is a major (and disruptive) update, there are changes in most supervisor codes : scripts need to be updated according to these changes. This is an on-going work in the rc branch of the COMPASS GitLab. This note will try to summarize all the major changes PEP 8 naming convention Basicaly, it can be summurised like this: class name = CamelCase function and variable names = snake_case For example: [Read More]
