High-performance computing (HPC) refers to the use of powerful computer systems to solve complex problems, often involving large amounts of data or complex simulations. HPC is used in many applications, such as weather forecasting, drug discovery, and financial modeling. Popular HPC platforms include IBM Blue Gene, Cray XC Series, and NVIDIA DGX. Boxing Object-oriented programming (OOP) is a programming paradigm that uses objects, which are instances of classes, to represent data and behavior. OOP allows for encapsulation, inheritance, and polymorphism, which can make code more modular and reusable. Popular object-oriented programming languages include Java, C++, and Python.
