Introduction to Polyphemus

Goals and Policy

Polyphemus is a Cyclops in Odyssey External link whose name roughly means "multiple speeches". It is consistent with the goals of the system, that is, gathering on the same platform:

It is written as much as possible with modern computer languages (mainly C++), and only perennial and scalable developments are included. Polyphemus is open. It is open source, distributed under GNU GPL, well documented (for users and developers), and released on a regular basis. Open also means that contributions from other teams are welcome.

Parallel computing is implemented in its main modules. Both OpenMP and MPI API are supported and allow shared-memory, distributed memory or hybrid parallel schemes.

Contents in Short

Polyphemus has a rich content which may be summarized with this list (in bold: key components or features):

Polyphemus is distributed with several other resources for the user: test cases, training sessions, a comprehensive user's guide, a scientific documentation for AtmoData, a reference documentation for AtmoPy. In addition, the development team can be contacted at Futhermore, resources are available on this website for new developers.
