The Effect of InfiniBand In-Network Computing on CAE Simulations

This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada

Resource Abstract

From concept to engineering, and from design to test and manufacturing, engineers from wide ranges of industries face ever increasing needs for complex, realistic models to analyse the most challenging industrial problems; Finite Element Analysis is performed in an effort to secure quality and speed up the development process. Powerful virtual development software is developed to tackle these needs for the finite element-based Computational Fluid Dynamics (CFD) simulations with superior robustness, speed, and accuracy. Those simulations are designed to carry out on large-scale computational High-Performance Computing (HPC) systems effectively.



The new generation of InfiniBand In-Network Computing technology includes several elements – the Scalable Hierarchical Aggregation and Reduction Protocol (SHARP™), a technology that enables to execute data reduction algorithm on the network devices instead of the host based processor. Other elements include smart MPI Tag Matching and rendezvoused protocol, and more. These technologies are in use at some of the recent large scale supercomputers around the world, including the top TOP500 platforms.



HPC-AI Advisory Council performed performance investigations including low level benchmarks and applications cases, to evaluate its performance and scaling capabilities with the InfiniBand interconnect.
