Problems solved by technology

[0003] Computing speed is particularly important for high-performance computing. High-performance computing will develop towards multi-core and many-core, and use heterogeneous parallelism to improve application computing speed. Currently, CPU+GPU is a very mature heterogeneous collaborative computing model. There are huge challenges in fine-grained parallel algorithms and large-scale parallel performance
