Digitalization in the hypercar industry has set the bar high for high-performance manufacturers

Rimac Technology, a high-tech powerhouse is challenging the hypercar industry with the record breaking Nevera, and their rapid prototyping done on all product levels. The supplier for the largest OEM’s in the world, such as Hyunday, Aston Martin, Porsche, Ferrari, Mercedes-Benz, Pininfarina, Koenigsegg, Renault or Jaguar is today in the driver’s seat of digitalization in the automotive industry.

Since the company relies on fast results, even faster product alterations and supreme quality end- result, it is understandable that the processes that accompany the product, have to be ultimately extremely fast and reliable. That is why the Rimac Technology company has adopted cloud computing to help with the designing, testing and ultimately with manufacturing of their components and hypercars, since Rimac Technology is well known for their efforts to produce every part in-house, which makes them unique in today’s global market.

Who do they work with?

To gain even greater scale and speed in their product development processes, Rimac Technology decided to implement Microsoft Azure HPC underpinned by AMD EPYC™ CPUs, primarily used in their various simulations for component and vehicle testing. Because of the company’s great need for prototyping every segment and new cutting-edge technology and components of the 2+ million € Nevera, engineering departments perform a large number of simulations for core components, which are electric motors, inverters, gearboxes and battery packs, and that is why these simulations are so crucial to the process of the final build. Simulations provide and enable precise data collection that can’t really be matched by the results of the physical testing, where something as simple as a misplaced sensor runs the risk of compromising the sensible data or can even cause damage on the valuable Nevera hypercar.

Although Rimac Technology started off with their own developed internal HPC cluster, in order to provide the computing resources for the innovation and iteration purposes, it was soon outgrown by the company’s growth. Today, they need greater scale and more powerful computing, and migration of workload from its internal HPC cluster to the cloud offered more valuable and improved simulations and models with added complexity and ultimately done in a faster and more efficient way.

Apart from the powerful infrastructure provided by Azure, Rimac Technology is also running its engineering simulations on UberCloud, which is essentially a cloud/application-agnostic platform that acts as an interface between cloud high-performance computing (HPC) infrastructure and engineering workflows. As a member of the Microsoft Partner Network, UberCloud runs simulation workflows in closed and highly secure software containers, which ensures that all application containers and simulation workflows, that Rimac Technology engineers run and need, get automatically loaded onto the Azure HPC cluster, which ensures a great overview of the workload for the engineers.

About the platforms used by Rimac Technology

UberCloud engineering simulation platform and container technology, running in Microsoft Azure and using 3rd generation AMD EPYC™ processors, integrates easily with existing IT architecture and infrastructure, which enables engineers to run challenging simulations or test larger batches of prototypes faster and more secure than ever before. In order to provide a better overview of the ongoing projects and simulations in the pipeline, Rimac Technology’s Azure HPC environment uses Azure CycleCloud to better organize and manage the clusters. This solution includes the Azure Virtual Machines, running containers on Azure HBv3 virtual machines with 3rd generation AMD EPYC™ Milan Processors with AMD 3D V-Cache, which are today state-of-the-art virtual machines for explicit calculations.

Rimac Technology engineers now have on-demand access to any additional and more powerful computing resources in the cloud and a quality overview provided for all engineers, whether they are working from home or the office. With these solutions, they have shortened the significantly shorter simulation time, which has a direct impact on product design cycle, superior level of quality with the ability to use more sophisticated geometries and physics and added quantity of iterations that can be run. Ultimately, with all the benefits of the cloud solutions, engineers can focus more on innovations and creativity in the field of product manufacturing.

Ivan Krajinović – statement about cloud services or products

Implementation of the cloud started with Proof of Concepts (PoCs) with several different cloud providers. It took us several months to finish the PoCs and to analyze all the results. Also, very importantly, we evaluated not only technical capabilities but also financial aspects and user- friendliness of the solution. Finally, we decided for Microsoft Azure and the UberCloud platform. Now, more than a year since migration to the cloud, we noticed many benefits and improvements in our work, from latest hardware like Milan X processors, on-demand super-powerful virtual machines for heavy loads to optimize costs of the with on-demand and spot pricing options. We can now do more complex models, faster and without a fear that some physics will not be captured due to computation limitations.

Ivan Krajinović from Rimac Technology will deliver one of the keynote sessions at European Cloud Summit, focusing on the use of cloud technologies to in modelling components for hyper-cars.
