Problems solved by technology

However, the development complexity of the programming languages ​​corresponding to these parallel modes is high, and there are different characteristics. Developers need to have certain parallel development experience and be proficient in using different types of programming environments. When the software and hardware architectures in the system change, Developers also need to modify the original program, but cannot automatically adapt
