Abstract:

Zenotech Ltd are a UK based company developing the latest in Computation Fluid Dynamics solvers and Cloud based HPC systems. Their Computation Fluid Dynamics solver (zCFD) has been engineered to take full advantage of the latest developments in GPU technology. This talk will present the performance advantages that Zenotech see when using GPUs and the impact this has on their customers. It will showcase industrial problems that have been solved in a fast/cost effective manner using a combination of zCFD and the P100 and V100 GPU's available on AWS. Traditionally these cases are run on in-house parallel computing clusters but the larger number of GPUs per node with AWS have enable the solving of large CFD problems on a single instance. Benchmarking with zCFD demonstrates that a single P3 node is providing the equivalent performance to over 1100 CPU cores. As well as performance benefits, the spot market and on-demand nature of AWS provide some real cost savings for Zenotech's customers and opens up a scale of simulation that was previously not affordable. The session will present real world examples from Zenotech's customers in the aerospace, renewable and automotive sectors. The session will also show how Zenotech's EPIC platform makes the combination of zCFD and AWS GPUs a simple and cost effective solution for engineers.

Abstract:
The impact of computational based Modelling and Simulation in providing industry with a competitive edge delivering higher performance and cost effective products is well documented and cannot be under estimated. This has, in the past been enabled by the year on year floating point performance improvements delivered by the processor and system manufacturers and has been the primary end user experience of Moore's law. The development of MultiCore technologies in all its wide variety of forms challenges this end user effect of Moore's law requiring a radical rethink of algorithms and their implementations just to maintain the same progress seen over the previous decades. The exploitation of GPU Computing promises to deliver a radical and affordable step change in simulation capability and this will be illustrated with details of a Computational Fluid Dynamics (CFD) solver (3D Finite Volume Unstructured) that demonstrates 20x performance benefits over the latest Intel Nehalem cores.
