We present a brief history of high-performance computing (HPC) through the lens of the tera-, peta-, and pre-exascale milestones. Key challenges and (potential) solutions are discussed and trends identified. An overview of the current HPC landscape is provided and, when coupled with technology roadmaps and evolving workloads, several possible avenues to practical exascale computing are identified. But many challenges remain and we discuss them in the context of several real world examples.
