5. Powerful "Xeon" processor brain

??? > No matter whether the PC or the server is involved in a price war on the entire machine market, all of them are emphasizing how powerful they are ", maybe we can compare the "strong human" brain with a "Xeon" processor. Most of the "mediocre" students, who have excellent intelligence since childhood, get high scores each time without spending too much time doing their homework, because, those students have a "Pentium" core since they were young. I am a mediocre student. I can only make up for my own shortcomings by relying on many books, but within a limited time, I have never been able to figure out so many complicated questions, and it is useless to work hard.
??? > According to one statistics, the idle time of most PCs is much longer than the used time. Although PC/OS vendors have designed a power-saving mode, they are still the "Household Appliances" that consume the most energy ". In another IT field, a group of enthusiasts try to connect thousands of normal PCs to challenge the giant servers in parallel processing mode. In addition, even with a "Xeon" processor, we cannot use a limited server to meet the infinite increase in access traffic because it is a single CPU, even if the operating system has designed a good multi-task system for him, however, it is still time-based.
??? > Our "strong people" face no different situations than these examples. As described in the previous "strong people" Diary, "Superman" will also be able to meet the needs of operation, if four dishes are lost in the sky, move your hands on your feet, and then you have to sit down on the ground and use the last one to catch 4th dishes, or keep standing with your mouth. This is the right to give up standing or to speak. In real life, "strong people" may face more cruel than this.
??? > The preceding assumption is that there is a "Strong Man" high-performance processor, and a high-stability operating system. All events can be performed in a well-organized manner, and one task can be completed without any space to implement the next one, "Strong people" within the range permitted by the number of tasks will not be faulty. Not all "strong people" are so lucky. They are installed in a lame operating system, and some data is lost after each process is suspended and then restored, most often, stack overflow causes the entire operating system to crash. Maybe the "Strong Man" is equipped with enough memory, so that he can stick to it for a period of time to reduce the number of overflow times. However, any company is often composed of not only strong people, but also a large number of General CPUs run on poor operating systems, with frequent overflow, frequent crashes, and frequent system reloading, this results in a backlog of tasks and greatly reduced service efficiency.
??? > Believe that you know the performance of your CPU and your operating system.
??? > In addition, the operating systems mentioned above refer to the popular multi-task operating systems. Because everyone wants to "multi-task ". The problem above has a relatively small impact on the single-task operating system ".
??? > The first condition for a multi-task operating system is that "the process is suspended and restored in the same state". The ngnc virtual machine has a concept of "slot ", this slot is used to keep the process status, including the stack information and structure. In order to make the ngnc virtual machine run well, the information stored in this slot is stable for many times I have studied/practiced. The concept of "order" in the "sculpture" system is like "slot". It carries the status information of each job task. whether a person is a strong person or not, if he accepts multiple tasks at the same time, he needs to clearly save the "orders" for these tasks and use his CPU to complete them in a time-based manner without confusion. The operating system clearly determines the order for each task.
