Abstract

We report GenASiS Mathematics provides modern Fortran classes furnishing extensible object-oriented functionality for the solution of fields governed by selected partial differential equations. The initial release included extensible object-oriented implementations of simple meshes and the evolution of generic conserved currents thereon. This revision - Version 2 of Mathematics - includes significant reorganization and streamlining of these classes, higher-order reconstruction by a different method, a Poisson solver, coarsening to avoid Courant time step limitations near coordinate singularities, and the offloading of computational kernels to GPUs.

GenASiS Mathematics: Object-oriented manifolds, operations, and solvers for large-scale physics simulations

Journal Article Cardall, Christian Y. ; Budiardja, Reuben D. - Computer Physics Communications

The large-scale computer simulation of a system of physical fields governed by partial differential equations requires some means of approximating the mathematical limit of continuity. For example, conservation laws are often treated with a ‘finite-volume’ approach in which space is partitioned into a large number of small ‘cells,’ with fluxes through cell faces providing an intuitive discretization modeled on the mathematical definition of the divergence operator. Here in this work, we describe and make available Fortran 2003 classes furnishing extensible object-oriented implementations of simple meshes and the evolution of generic conserved currents thereon, along with individual ‘unit test’ programs andmore »« less

GenASiS Basics: Object-oriented utilitarian functionality for large-scale physics simulations (Version 3)

Journal Article Budiardja, Reuben D. ; Cardall, Christian Y. - Computer Physics Communications

GenASiS Basics provides Fortran 2003 classes furnishing extensible object-oriented utilitarian functionality for large-scale physics simulations on distributed memory supercomputers. This functionality includes physical units and constants; display to the screen or standard output device; message passing; I/O to disk; and runtime parameter management and usage statistics. This revision – Version 3 of Basics – includes a significant name change, some minor additions to functionality, and a major addition to functionality: infrastructure facilitating the offloading of computational kernels to devices such as GPUs.

GenASiS Basics: Object-oriented utilitarian functionality for large-scale physics simulations

Journal Article Cardall, Christian Y. ; Budiardja, Reuben D. - Computer Physics Communications

Aside from numerical algorithms and problem setup, large-scale physics simulations on distributed-memory supercomputers require more basic utilitarian functionality, such as physical units and constants; display to the screen or standard output device; message passing; I/O to disk; and runtime parameter management and usage statistics. Here we describe and make available Fortran 2003 classes furnishing extensible object-oriented implementations of this sort of rudimentary functionality, along with individual `unit test' programs and larger example problems demonstrating their use. Lastly, these classes compose the Basics division of our developing astrophysics simulation code GenASiS (General Astrophysical Simulation System), but their fundamental nature makes themmore »« less

Targeting GPUs with OpenMP directives on Summit: A simple and effective Fortran experience

Journal Article Budiardja, Reuben D. ; Cardall, Christian Y. - Parallel Computing

We use OpenMP to target hardware accelerators (GPUs) on Summit, a newly deployed supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), demonstrating simplified access to GPU devices for users of our astrophysics code GenASiS and useful speedup on a sample fluid dynamics problem. We modify our workhorse class for data storage to include members and methods that significantly streamline the persistent allocation of and association to GPU memory. Users offload computational kernels with OpenMP target directives that are rather similar to constructs already familiar from multi-core parallelization. In this initial example we ask, “With a given number of Summitmore »« less
