As our industry pushes the frontiers of hydrocarbon recovery, complexity and risk management are increasingly pervasive dimensions of the landscape. Highperformance computing (HPC) is providing new ways to address complexity and risk by opening more workflows to the "real time" world of operations.
Cray supercomputers—named for inventor Seymour Cray—were introduced in the 1960s and became synonymous with this new breed of computer. Supercomputer performance is measured in floating point operations per second (FLOPS), which measures the number of calculations or instructions performed in a given time. This is generally used with an International System of Units (SI) prefix such as mega-, giga-, tera-, or peta- to describe the machine’s power or class. Today’s supercomputers are "petascale" machines, capable of processing one quadrillion (1015 ) FLOPS. However, they are the size of several rooms and require megawatts of power to operate, making them impractical and costly for all but the most esoteric and specialized problems.
