Parallel algorithm and parallel programming: from specialty to generality as well as software reuse

JAUMIN: a programming framework for large-scale numerical simulation on unstructured meshes

“…3b, the self-definition of new element shapes are as simple as the creation of a derived class from the "ElementShape" class coupled with the implementation of the pure virtual functions for three adjacencies. Figure 4 shows the nested mesh hierarchy model (Mo et al 2016) implemented in JAUMIN. After the geometry is discretized into a mesh level in the hierarchy, the level is subdivided into sub-domains called domains.…”

“…Different from the algorithm frameworks, JASMIN (Mo et al 2016;JASMIN 2018) is a general-purpose parallel programming framework on structured-mesh for numerical simulation. This framework provides a parallel programming model, on top of which a massively parallel code can be developed without writing of parallel codes, i.e.…”

“…A prototype of JAUMIN was introduced on HPSC2016 for the first time (Liu et al 2016). In the past 2 years, we reconstructed JAUMIN towards the component and model/ pattern-driven software architecture technologies.…”
