High-Performance Spectral Element Methods on Field-Programmable Gate Arrays
Martin Karp, Artur Podobas, Niclas Jansson +4
Improvements in computer systems have historically relied on two well-known observations: Moore's law and Dennard's scaling. Today, both these observations are ending, forcing comp…
tf-Darshan: Understanding Fine-grained I/O Performance in Machine Learning Workloads
Steven W. D. Chien, Artur Podobas, Ivy B. Peng +1
Machine Learning applications on HPC systems have been gaining popularity in recent years. The upcoming large scale systems will offer tremendous parallelism for training through G…
sputniPIC: an Implicit Particle-in-Cell Code for Multi-GPU Systems
Steven W. D. Chien, Jonas Nylund, Gabriel Bengtsson +3
Large-scale simulations of plasmas are essential for advancing our understanding of fusion devices, space, and astrophysical systems. Particle-in-Cell (PIC) codes have demonstrated…
Optimization of Tensor-product Operations in Nekbone on GPUs
Martin Karp, Niclas Jansson, Artur Podobas +2
In the CFD solver Nek5000, the computation is dominated by the evaluation of small tensor operations. Nekbone is a proxy app for Nek5000 and has previously been ported to GPUs with…
