High-performance computing refers to the use of advanced computing technologies and infrastructure to solve complex problems or perform computationally-intensive tasks at a much faster rate than traditional computing systems. This field typically involves the use of parallel processing, large-scale data storage, and specialized hardware to achieve high levels of performance and efficiency. High-performance computing is commonly used in scientific research, engineering, data analysis, and other applications that require rapid processing of large volumes of data. Researchers in this area focus on developing new algorithms, software, and hardware techniques to optimize performance and scalability of computing systems.
