%0Computer Program %TORNL/grit %XGrit is a software library designed specifically for conducting particle-based Lagrangian simulations with CPU/GPUperformance portability. This library allows researchers and engineers to perform a wide range of simulations, including multiphase flow, and more. Grit employs Message Passing Interface (MPI) for distributed memory parallelism and Kokkos programming model for on-node shared memory parallelism with performance portability across different architectures of GPUs and multi-core/manycore CPUs. %AGe, Wenjun %ASankaran, Ramanan %Rhttps://doi.org/10.11578/dc.20230622.1 %Uhttps://www.osti.gov/doecode/biblio/108669 %CUnited States %D2023 %GEnglish %2USDOE Office of Science (SC) %1AC05-00OR22725 2023-06-22
