Talking about multi-core CPU, multi-threading, multi-process

1.CPU Development TrendThe number of cores will continue to increase, according to Moore's Law, because a single core performance improvement has a serious bottleneck problem, the average desktop PC is expected to reach 24 core (or 16 core 32 threads) in the early 2018 of 2017, how can we face this sudden rise in the number of cores? Programming also needs to evolve with the times. I venture to predict that the chip bus between each core of the CPU will be connected by 4-way group:), because the
