alien version 2.1.0 has been released featuring better usability. Please read the release notes for all changes.

  • [January 1, 2021]

A demonstration video for an experimental GPU rendering method is available. It has been developed at the features/GpuVectorView branch and visualized the inner structures of the simulated bodies. The mentioned video shows different replicators in action.

  • [August 25, 2020]

The development of alien - version 2.0.0 has been finished. It provides an extreme performance boost by making use of computations and parallelization techniques on GPU devices.

  • [January 11, 2020]

All algorithms for alien simulation are now implemented in CUDA. The changes have been merged into the developer branch and will be released soon.  

  • [January 15, 2019]

First results on GPU computations with CUDA seem promising. The prototypical alien physics engine on CUDA exhibits a high performance boost of about 10 times in comparison to a related CPU simulation. The measurements have been made on a system with core i7-6700 and GeForce 2080 TI.

  • [September 30, 2018]

The new feature branch feature/CUDA has been created in order to develop support for GPU computing.

  • [August 9, 2018]

An installer of alien for Microsoft Windows 10 is now available.

  • [August 9, 2018]

After many years of development version 1.0.0 of alien including a comprehensive documentation has been released. The source code is available on the master branch in the alien-GitLab repository.

Predecessor project

The alien project was strongly inspired by a predecessor project named alien0. The conducted research studies and experiences have led to many new ideas that where incorporated in the present simulation software. In particular the need for a more realistic physics framework and extended programming capabilities of the artificial structures.
