DRAMA: A Library for Parallel Dynamic Load Balancing of Finite Element Applications
We describe a software library for dynamic load balancing of finite element codes. The application code has to provide the current distributed mesh and information on the calculation and communication requirements, and receives from the library all necessary information to re-allocate the application data. The library computes a new partitioning, either via direct mesh migration or via parallel...
متن کاملDynamic load-balancing of ®nite element applications with the DRAMA library
The DRAMA library, developed within the European Commission funded (ESPRIT) project DRAMA, supports dynamic load-balancing for parallel (message-passing) mesh-based applications. The target applications are those with dynamic and solution-adaptive features. The focus within the DRAMA project was on ®nite element simulation codes for structural mechanics. An introduction to the DRAMA library wil...
متن کاملParallel 3D Adaptive Compressible Navier-Stokes Solver in GeoFEM with Dynamic Load-Balancing by DRAMA Library
Grid adaptation is a very useful method for applications with unstructured meshes but requires dynamic load-balancing for efficient parallel computation. In this study, a parallel 3D compressible Navier-Stokes code with adaptive hybrid meshes (epHYBRID) and parallel adaptation procedure (pADAPT) have been developed on GeoFEM parallel platform. The DRAMA library has been integrated into the pADA...
متن کاملDynamic load balancing for large-scale adaptive finite element computation
For the parallel computation of partial differential equations, one key is the grid partitioning. It requires that each process owns the same amount of computations, and also, the partitioning quality should be proper to reduce the communications among processes. When calculating the partial differential equations using adaptive finite element methods, the grid and the basis functions adjust in...
متن کاملDynamic Load Balancing for Finite Element Calculations on Parallel Computers
Computational requirements of full scale computational fluid dynamics change as computation progresses on a parallel machine. The change in computational intensity causes workload imbalance of processors, which in turn requires a large amount of data movement at runtime. If parallel CFD is to be successful on a parallel or massively parallel machine, balancing of the runtime load is indispensab...
