High-Performance-Computing plays a leading role in our current energy business and will be of critical importance for a successful energy transition. Looking across multiple industries, our business undoubtedly exploits the largest High-Performance-Computing capacity. HPC helps in seeking higher productivity, lowering costs and making better use of huge amounts of data through high-performance simulation and data analytics. Algorithms performing as fast as possible on the best available hardware have a direct impact on many of the decisions shaping our business. This is particularly true in this post COVID world. Achieving this goal, through the various forms of HPC, from Supercomputers on premise to elastic and versatile solutions on the cloud, is the underlying theme of this fifth instance of the EAGE HPC for Upstream: “Heterogeneous HPC: Challenges, Current and Future Trends”.
