OpenFPM: Distributed data-structures for particle and particle-mesh codes on parallel computers
NHR Workshop (Online)
Date will be announced soon, planned for Q1 2025
Speakers: Serhii Yaskovets & Pietro Incardona
Scalable and efficient numerical simulations continue to gain importance, as computation is firmly established as the third pillar of discovery, alongside theory and experiment. Meanwhile, the performance of computing hardware grows through increasing heterogeneous parallelism, enabling simulations of ever more complex models. However, efficiently implementing scalable codes on heterogeneous, distributed hardware systems becomes the bottleneck. This bottleneck can be alleviated by intermediate software layers that provide higher-level abstractions closer to the problem domain, hence allowing the computational scientist to focus on the simulation. Here, we present OpenFPM, an open and scalable framework that provides an abstraction layer for numerical simulations using particles and/or meshes. OpenFPM provides transparent and scalable infrastructure for shared-memory and distributed-memory implementations of particles-only and hybrid particle-mesh simulations of both discrete and continuous models, as well as non-simulation codes. This infrastructure is complemented with frequently used numerical routines, as well as interfaces to third-party libraries. In this workshop, we will see the basic data structures in OpenFPM and basic operations for parallel programming on CPUs and GPUs. In the second part, we will see how these can be used to construct simulations.
