Comparing across multiple industries, our energy business undoubtedly exploits the largest High-Performance-Computing capacity. HPC plays a central role in seeking higher productivity, lowering costs and making better use of our data through high-performance simulation and data analytics. This is especially true while our industry experiences change through this fourth industrial revolution (4IR): digitalization. Algorithms performing as fast as possible on the best available hardware either on premise or in the cloud have a direct role and impact on many of the decisions shaping our business. The overlap and cross pollination opportunities between data analytics, big data, AI, simulation and HPC is the underlying theme of this fourth instance of our HPC workshop: HPC through the 4IR.
