Software

A succinct description and links towards the main project outputs - massively parallel multi-GPU solvers.

Current software development is hosted on the following GitHub organisations:

• PTsolvers organisation
  • FastIce.jl Parallel (multi-)xPU iterative fast ice flow solvers
  • JustRelax.jl Pseudo-transient accelerated iterative solvers for geodynamic models

• JuliaGeodynamics organisation
  • GeoParams.jl Define material parameters and perform non-dimensionalization for geodynamic simulations
  • JustPIC.jl (multi-)xPU particles-in-cell advection scheme
  • GeophysicalModelGenerator.jl Import, process and interpret geophysical data sets to be used in numerical models
  • GeoDataPicker.jl Browser-based Graphical User Interface to interpret 3D geological and geophysical data
  • InteractiveGeodynamics.jl Browser-based Graphical User Interface to run geodynamic models with LaMEM
  • LaMEM.jl Julia interface to LaMEM, which installs it and allows setting up, running and reading LaMEM simulations
  • CompGrids.jl Create computational grids that can be used with ParallelStencil.jl or PETSc.jl

• Building blocks
  • ParallelStencil.jl Package for writing high-level code for parallel high-performance stencil computations that can be deployed on both GPUs and CPUs
  • ImplicitGlobalGrid.jl Almost trivial distributed parallelization of stencil-based GPU and CPU applications on a regular staggered grid
  • AMDGPU.jl AMD GPU (ROCm) programming in Julia
  • KernelAbstractions.jl Heterogeneous programming in Julia

• Proof-of-concept packages
  • ROCm-MPI ROCm (-aware) GPU MPI tests on (pre-) exascale supercomputers
  • PT-AD Pseudo-transient automatic differentiation playground
  • Stokes2D_simpleVEP 2D viscoelastoplastic localization
  • MagmaThermoKinematics 2D/3D thermal models of lithospheric-scale magmatic systems following dike injection
