[MGI22-P05] Formura: Programming Language for High-performance Structured Lattice Stencil Computation

*Takayuki Muranushi1, Junichiro Makino1 (1.RIKEN Advanced Institute for Computational Science)

Keywords:simulation geoscience, structured lattice simulation, High-performance computing

Recently, programming and performance optimization have become a big burden in simulation science. In studies of planetary formation and evolution, many applications can be reduced to explicitly solving some partial differencial equations (PDEs). We have been developing Formura, a programming language for stencil computations, that can generate explicit solver codes for PDEs.
In formura, we can describe discretized PDE-solving algorithms using convenient and familiar mathematical notations such as functions, discretized differentiation operators, rational lattice indices such as half-grid coordinates. We will report the current development status, sample codes, and performance measure of formura.
