While the Industry section of the latest TOP500 list of worldwide supercomputers is dominated by oil and gas companies (6 out of the top 10), there are no new O&G machines in the list. Top performer is ENI’s 2020 HPC5 Dell Power Edge based system at a reported 35 petaflops closely followed by ExxonMobil’s 2022 Discovery from Cray at 26 pf. Saudi Aramco has two machines in the top 10 (Dammam-7 and Ghawar-1), both Cray-based systems. Petrobras’ Pégaso from SuperMicro and TotalEnergies IBM-based Pangea III complete the Industry top 10. Systems are mostly based on AMD CPUs with Nvidia GPU co-processors. All run Linux of course. A word of caution: the Top500 is largely self-reported, many HPC operators may not wish to join in the competition. Moreover, evaluation is based on a somewhat artificial Linpack benchmark so your mileage may vary.
