high-performance computing

on-demand access to HPC and domain-specific resources is already happening using the cloud. Multiple product data management and

computer-aided design systems are a fact of life for engineers, making simulation lifecycle management increasingly relevant. We continue to see high-fidelity models, long compute cycles, and big data. Web-based remote visualisation and application integration are instrumental for pre- and post-processing. License mobility, short-term usage business models, minimal movement of data, ease of use, ease of access, and traceability are paramount.

Technology democratisation Smaller entities in both the public and private sector have begun to adopt HPC. Clusters have become less expensive. With the advent of appliance computing and ‘cluster-ready’ designations, implementation has become simpler. Adoption of computer-aided engineering methods is also more widespread, particularly on the front end of the design process. Tis means that a greater number of innovators have access to the tools they need. 3D printing has become accessible to most commercial entities. Topology optimisation

and 3D printing are moving from high- end applications to more general usage. Both technologies are disruptive: topology optimisation to established design processes, and 3D printing to the manufacturing process. More access to computing power is enabling

more of us to take steps to improve our analysis capabilities. However, there is still a technology race among those competing to get the supercomputing resources required to conduct top tier research. An entity may not be able to rationalise the purchase of elite supercomputing resources when the computation is only done once a month. A cloud infrastructure will ease this burden.

The pace of innovation Physics-based simulation is powered by HPC. Te fidelity of these models is getting better and better. An expansion to sound and touch is likely in our lifetimes. Te explosion of data will continue, but energy-efficiency at exascale levels is desirable and possible. We see a single pane of glass, through which a user may access infinite computing power, soſtware parallelisation, increased design exploration, complex, high- fidelity models, and simulation data.

Te body of knowledge is expanding

exponentially for humankind. Leveraging this knowledge in conjunction with advanced computing power has tremendous potential for improving the world as we know it. Applied physics and mathematics enable us to manage complexity and see things differently. Human- computer interaction and user experience will play a pivotal role in how we access and manipulate technology. Scientists and engineers apply their passion,

talent and experience to innovate. To do so, they must have the tools they need, without being restricted by limits to computing power, undue complexity, or access to resources. Te ability to employ technology in the pursuit of knowledge is a critical success factor. Te freedom to think, to experiment, to try something new, to fail without repercussion in the pursuit of something better: these characteristics are the hallmarks of a culture in which innovation flourishes, one which will enable us to see clearly in order to create a better world.
