High performance computing (HPC) is a field of computer science that focuses on developing and using supercomputers and parallel processing techniques to solve complex computational problems that require massive amounts of calculation. HPC systems typically consist of multiple processors working together to perform calculations at much faster speeds than traditional computing systems. HPC is used in a variety of scientific, engineering, and business applications, including weather forecasting, climate modeling, financial modeling, and drug discovery. HPC systems require specialized hardware and software to optimize performance, and researchers in this field work to develop algorithms and techniques for efficiently utilizing the processing power of these systems. Overall, high performance computing plays a crucial role in advancing research and innovation in various fields by enabling researchers to tackle larger and more complex problems that would be impossible to solve with traditional computing methods.
