Mint User Guide¶
Mint provides a comprehensive mesh data model and a mesh-aware, fine-grain, parallel execution model that underpins the development of computational tools and numerical discretization methods. Thereby, enable implementations that are born parallel and portable to new and emerging architectures.
- Support for 1D/2D/3D mesh geometry.
- Efficient data structures to represent Particle Mesh, Structured Mesh and Unstructured Mesh types, including unstructured meshes with Mixed Cell Type Topology.
- Native support for a variety of commonly employed Cell Types.
- A flexible Mesh Storage Management system, which can optionally inter-operate with Sidre as the underlying, in-memory, hierarchical datastore, facilitating the integration across packages.
- Basic support for Finite Elements, consisting of commonly employed shape functions and quadratures.
- A Mesh-Aware Execution Model, based on the RAJA programming model abstraction layer that supports on-node parallelism for mesh-traversals, enabling the implementation of computational kernels that are born parallel and portable across different processor architectures.
Mint is designed to be light-weight and self-contained. The only requirement for using Mint is a C++11 compliant compiler. However, to realize the full spectrum of capabilities, support for the following third-party libraries is provided:
- RAJA, used for the parallel execution and portability layer.
- Conduit , for using Sidre as the Mesh Storage Management system.
- Umpire, for memory management on next-generation architectures.
