Abstract: Mantevo MiniAMR is a miniapp for adaptive mesh refinement (AMR) that mimics commonly found workloads and communication patterns in AMR applications, compact proxy for octree-based AMR. Adaptive Mesh Refinement is a frequently used technique for efficiently solving partial differential equations (PDEs): A finer mesh is used in regions that require a higher resolution (e.g., because of turbulence), and a coarse mesh is used to cover less sensitive regions. The authors describe integration of MiniAMR and OpenTS parallel programming system. There is performed comparison between OpenTS DMPI and Open MPI. (In Russian).

Key words and phrases: dynamic parallelization, T-system with an open architecture, OpenTS, T++ programming language, adaptive algorithm, adaptive mesh refinement.
