A study on the performance of distributed training of data-driven CFD simulations
Iserte, Sergio; González-Barberá, Alejandro; Barreda-Juan, Paloma; Rojek, Krzysztof Sage (2023-05-04)Data-driven methods for computer simulations are blooming in many scientific areas. The traditional approach to simulating physical behaviors relies on solving partial differential equations (PDEs). Since calculating these ... -
An study of the effect of process malleability in the energy efficiency on GPU‑based clusters
Iserte, Sergio; Rojek, Krzysztof Springer (2019-10-21)The adoption of graphic processor units (GPU) in high-performance computing (HPC) infrastructures determines, in many cases, the energy consumption of those facilities. For this reason, an efficient management and ... -
Modeling power consumption of 3D MPDATA and the CG method on ARM and Intel multicore architectures
Rojek, Krzysztof; Quintana-Orti, Enrique S.; Wyrzykowski, Roman Springer-Verlag (2017-03)We propose an approach to estimate the power consumption of algorithms, as a function of the frequency and number of cores, using only a very reduced set of real power measures. In addition, we also provide the formulation ... -
Optimizing throughput of Seq2Seq model training on the IPU platform for AI-accelerated CFD simulations
Rościszewski, Paweł; Krzywaniak, Adam; Iserte, Sergio; Rojek, Krzysztof; Gepner, Pawel Elsevier (2023)Intelligence Processing Units (IPU) have proven useful for many AI applications. In this paper, we evaluate them within the emerging field of AI for simulation, where traditional numerical simulations are supported by ...
