Heterogeneous computing is a new computing model after single-core computing and multi-core parallel computing. Which of the following descriptions about the background of heterogeneous computing is wrong?

• A.The performance improvement brought by multi-core parallelism is limited. With the increase of parallelism, the problems of heat dissipation and energy consumption have become increasingly prominent.
• B.Heterogeneous computing maximizes the performance of each processor, and delegates the most suitable task to the best computing unit.
• C.Moore's Law is getting closer and closer to the physical limit, and the difficulty and cost of improving single-core performance are getting higher and higher.
• D.NUMA is a mode of heterogeneous computing.
