The technical edition of "New Scientist" magazine recently published a popular science article that introduced a new type of computer that researchers at the University of London are developing that is said to never crash. The content of the article is as follows: After the chaos is over, order is ushered in. Now there is a brand new computer that can imitate the randomness of nature to repair the damaged data, so as to recover from the crash state instantly. This new type of computer is called a "systemic computer" and has a self-healing function. The University of London already uses this computer to run business-critical systems. For example, it can allow drones to reprogram themselves to repair battle damage; or help create a more realistic human brain model. The computers that people use every day are not suitable for modeling natural processes such as how neurons work or how bees gather. This is because their operation is slow and continuous, and only one instruction can be executed at a time. University of London computer scientist Peter Bentley said: "Nature is never like that. Many processes in nature are distributed, decentralized and random. And many processes in nature With tolerance, you can fix it yourself. A computer should be able to do that too. " Today's computers can work steadily through a series of instructions, read and execute an instruction from memory, and then feed back the results of the calculation to memory. Then this process is repeated continuously, so that the entire calculation process is completely controlled by a sequence timer called a program counter. Although this calculation method is very suitable in some applications, it is not suitable for synchronous computing applications. Bentley said: "Even if you feel that your computer is running all your software at the same time, it just pretends to do that. It just switches between programs quickly." He and Christos Sakellariou of the University of London jointly developed a new computer capable of combining data and related instructions. For example, it can combine temperature with instructions on what measures should be taken if the temperature is too high. Then inject the results into different system data pools respectively. Every system has a memory containing context sensitive data, which means it can only affect other similar systems. This system does not use a program counter, but executes instructions at random time points selected by a pseudo-random number generator. The purpose of this is to imitate the randomness of nature. Bentley claims that these systems can execute their instructions at random, and that no system has a higher priority than another system. He said: "The interaction between these systems is simultaneous and random, and the results of the calculation will emerge from those interactions." This mode does not sound like work, but in fact it can work, and work faster than expected. In April this year, a conference on evolvable systems will be held in Singapore, where Bentley will introduce the computer. Importantly, an architectural computer contains multiple copies of instructions distributed across many systems, so if one of the systems is damaged, the computer can immediately access another uncorrupted copy to repair its software code. Traditional operating systems crash when they cannot access memory, but an architectural computer is different. It can still function normally under similar conditions, because each independent system has its own memory. Bentley and Sacrario are studying how to use machine learning technology to teach computers to rewrite their own software code when the environment changes in order to respond to environmental changes. Steve Furber of the University of Manchester said: "This is an interesting job." Ferber is developing a billion-neuron computer similar to the human brain, which he calls Spinnaker. . In fact, he can even help the R & D team of the University of London to solve some problems. He said: "Spinnaker will be an excellent programmable platform, very suitable for modeling large-scale systematic computer systems."
