Main features

FOODiE has many features, here the main ones are listed.

• Pure Fortran implementation;
• KISS and user-friendly:
  • simple API, presently based on the Rouson's Abstract Data Type Pattern [1];
  • easy building and porting on heterogeneous architectures;
• comprehensive:
  • explicit Euler scheme, 1st order accurate;
  • explicit Runge-Kutta schemes:
    • TVD or SSP schemes, see [2]:
      • 1 stage, namely the forward explicit Euler scheme, 1st order accurate;
      • 2 stages, 2nd order accurate;
      • 3 stages, 3rd order accurate;
      • 4 stages;
      • 5 stages, 4th order accurate;
  • implicit Runge-Kutta schemes;
  • low-storage explicit schemes, see [2,3,3];
  • Leapfrog, 2nd order accurate:
    • Robert-Asselin filter, for stability and leapfrog, 1st order accurate;
    • Robert-Asselin-Williams filter, for stability and leapfrog, 3rd order accurate;
  • Adams-Bashforth variants of 2nd and 3rd order accurate;
• efficient:
  • high scalability on parallel architectures:
    • support for shared memory multi/many cores architecture;
    • support for distributed memory cluster;
    • support for GPGPU/accelerators device;
• Tests-Driven Developed (TDD):
• well documented:
  • clear documentation of schemes implementations;
  • complete API reference;
  • comprehensive wiki:
• collaborative developed;
• FOSS licensed;
