Alya assembly
Program's name: Alya assemblyAvailable version(s): Programming language(s): Fortran ·
Programming model(s): OpenMP ·
Alya is a simulation code for high performance computational mechanics. Alya solves coupled multiphysics problems using high performance computing techniques for distributed and shared memory supercomputers, together with vectorization and optimization at the node level.
This kernel corresponds to the algebraic system assembly of a finite element code (FE) for solving partial differential equations (PDE’s). The matrix assembly consists of a loop over the elements to compute element matrices and right-hand sides and their assemblies in the local system.
There are two available versions of this kernel:
- baseline: which makes use of atomic constructs to synchronise access to shared data.
- multidependencies: which leverages the use of multidependencies features provided by OmpSs programming model to avoid the use of atomic constructs.
