OPS

Developing an open-source framework for the execution of multi-block structured grid applications

The OPS (Oxford Parallel Structured software) project is developing an open-source framework for the execution of multi-block structured mesh applications on clusters of GPUs or multi-core CPUs and accelerators. Although OPS is designed to look like a conventional library, the implementation uses source-source translation to generate the appropriate back-end code for the different target platforms.

Funding for OPS development is coming from:

  • EPSRC through support for the project on "Future-proof massively-parallel execution of multi-block applications"

Main Developers:

Other Developers/Collaborators:

  • Endre László (PPKE Hungary) 
  • Andrew Mallinson, David Beckingsale, Oliver Perks (Warwick)

Other collaborators are very welcome, either as developers of OPS, or as users to provide feedback on the software, documentation, etc.
