Scientists at the University of Glasgow have focused on improving the search speed, hoping to reduce energy consumption by increasing the speed. Dr. will Vanderbilt of the research team pointed out that people will consider the carbon cost of running information technology. They may be very aware of the power consumption of using computers, but they may not pay attention to the energy consumption when using online search. Although there are many ways to reduce the energy consumption of data centers, reducing search time is their focus. By increasing the search speed, the energy consumed by the server under the same workload will be reduced.
The research team used Xilinx FPGAs to perform information retrieval and database document filtering algorithms. The results show that the search speed of FPGA system is 20 times faster than that of Intel An Teng -2 dual-core processor. Moreover, the power consumption of FPGA chips is very small, and each chip only needs to consume 1.25 watts, while the Itanium processor needs to consume 130 watts.
Dr. Azwopadi, another member of the research team, said that FPGAs can reduce energy consumption and improve computing speed, which has great potential and is expected to bring huge economic benefits. If several FPGAs are connected to a processor, the operation speed will be greatly improved, leaving only a few carbon footprints.
Scientists hope to further develop the system and finally apply it to the network server, so as to speed up the network search and reduce the energy and carbon costs required by the search engine. At present, they are working hard to further improve the performance of the prototype and test the data center environment.

2. Green Internet constitutes a green touch.
In a blink of an eye, autumn has passed and winter has quietly arrived. Looking around, the green gradually faded, replaced by those yellow eyes full of melancholy, and sadness and melancholy came to mind unconsciously.
That day, my classmates and I went out to the supermarket and were about to leave. Suddenly, my eyes lit up: green eyes! Unable to restrain my joy, I stopped in front of a bonsai shop and went in. My heart suddenly calmed down. On this bustling and noisy road, here is a piece of pure land, placed in large and small bonsai, breathing the fresh fragrance of green leaves, feeling that I have entered a forest in early spring, surrounded by the green of life, and the exquisite flowers and plants in front of me are so full of vitality. I decided to bring a little green. After several selections, a pot of aloe attracted me, not only because of the exquisite flowerpot, but also because of the lovely elf in the flowerpot. Although it is not big, it shows the exuberance and excitement of life, which makes me fondle admiringly.
In this way, my desk has a touch of green, and I take care of it every day, just to make the only touch of green in the classroom shine. The morning light in winter is a little cold but clear. I came to the classroom early, took it out of the drawer, let it bathe freely in the sun, and then poured a small cover of water as usual. Glittering water drops slipped from the tip of the blade, accompanied by sunshine, spilling a table of broken silver. The morning light reflects the whole aloe, which is so clear and attractive, like jade cast by clear water. This touch of green in front of me fills my heart with joy and relaxation, and I meet the challenge with a better attitude!
Thanks to the touch of green in my heart, it purifies my soul, keeps me awake and pure in the winter when everything is sleeping, gives me the motivation to move forward, and makes me more actively and enthusiastically devote myself to my study and life under the guidance of this vibrant green.
I love a sentence in "The Reader": "Life has no rehearsal, every day is live broadcast". Indeed, we can neither dwell on the past nor know the unknown tomorrow. All we can do is seize today. I hope everyone has a touch of green in their hearts, so that today's life is as gorgeous and dazzling as this touch of green, and it will bloom forever!

Green is the true color of nature; Green is the color of our hearts.
I am a computer puzzle. I often play games online. As long as my hand touches the keyboard, I won't be happy. After a long time, my eyesight dropped, my spine ached and my back was hunched. Because I was preoccupied with playing games when I wrote my homework, my academic performance also declined. Mom sees it in her eyes and is anxious in her heart. If she wants to control my surfing the Internet, she must "make three chapters" with me: first, she must surf the Internet healthily; Second, do something useful online, not just play games; Third, you must finish your homework before surfing the internet, and the time should not be too long. But mom, how can she look at me? I always surf the internet without telling my mother when I have time, and play until my mother comes back from work.
Unfortunately, the time is not long. One day, when my mother came back from work, she proudly said to me, "You the Monkey King, no matter how fierce you are now, can't escape the palm of my hand. Now that we surf the Internet in a green way, you can't play computer at will. " "Green Internet access?" I said strangely, "I have only heard of green environmental protection and protecting green homes, but I have never heard of green internet access!" " "My mother said happily to me," Now Internet value-added services provide Internet content filtering services. With it, I can effectively set your access rights and time to surf the Internet, shield the influence of bad information on you, prevent you from indulging in the Internet, flexibly control the time and duration of your surfing the Internet, and ensure that you study, rest and surf the Internet correctly.
"Is there really such a god?" I sat in front of the computer with a grain of salt. Sure enough, as my mother said, I just clicked on a website at random, and the system immediately popped up a page that refused to visit. I had to enter through my mother's "service password". I begged my mother to let me in, but when I was having a good time, the system reminded me that "it's time to have a rest." Had to bite the bullet and get off the assembly line.
"I didn't lie to you, did I?" Mother said meaningfully: "Son, the green Internet has provided you with a safe, pure and healthy network sky, so you should cherish it!" " "
From then on, I only need to play the game online for a while after finishing my homework, but because of the computer teacher's reminder, the game will automatically close. Under the guidance of my teacher, my ability to search, collect and process information on the Internet has been greatly enhanced. Teachers often praise me! Green surfing the Internet can reassure parents and make us have fun. This is really "enjoy the green internet, we will grow up healthily!"
Article 2:
2 1 century is an information age full of competition. With its rich content, broad vision and convenient way, the Internet presents us with a beautiful and wonderful new world, enabling people to learn about major events at home and abroad and learn various cultural knowledge at the first time without leaving home.
Ever since I learned computer, I have always felt that surfing the Internet is a very meaningful thing, so I asked my father to buy me a computer. Since then, I have been roaming in the online world by computer whenever I have time. Once, I saw a terrible headline on the news website, "Brain death after surfing the Internet for 5 hours". I was startled by the title. It turned out that two college students went to the internet cafe to play universal games after class and played for more than six hours. One of them suddenly felt a headache and they had to go back to school. Another college student was busy looking for a car, took a numb college student to the hospital and informed the school teacher. Through the doctor's emergency rescue, the college student finally saved his life, but became a vegetable. After reading this news, I feel that spending too much time online will also bring harm to people, and there are also many problems. First of all, surfing the internet is easy to make people numb, waste time and money, neglect their studies, especially children's poor self-control ability. After surfing the Internet, they have no intention to study. Secondly, there are many unhealthy things on the internet, and teenagers will unconsciously fall into a trap, unable to extricate themselves, and finally lose their future. There is also a long time online, and it is easy to get many diseases, such as low back pain, stomach trouble, myopia and so on. , and finally ruined people's health.
From this, I deeply realized that we should make rational use of time, surf the Internet green and grow up healthily. I hope everyone will close their eyes and be a qualified citizen.
4. Green Internet Essay The new century calls for a green life.
Today, the network is getting closer and closer to our study and life. I hope the society can build a green grid so that everyone can swim in a clean tennis pool. Green Internet access must first have a healthy network.
I think it is appropriate to compare the website to a swimming pool. Swimming itself is healthy, but if some swimming pools are not sanitary enough, people who go swimming may get sick or even die. Therefore, in the face of the current mixed websites, it is hoped that law enforcement officers can identify a number of black nets and order them to rectify until the "water" in the "net pool" is changed clean before reopening.
In addition, I suggest that Quanzhou set up a student network by itself, so that all teenagers can surf the Internet happily and enjoy the convenience brought by the network to study and life. Secondly, green Internet access should have a sound system.
I think it is because the system is not perfect enough that all kinds of unsafe factors in internet cafes will appear. At present, the state has banned minors from surfing the Internet in commercial Internet cafes. I found that there is also a sign in front of many Internet cafes-"No minors allowed", but after a closer look, there are still many Internet cafes that secretly accept minors to surf the Internet.
I think the system has been set and it has to be implemented by people. If there is a shortage of law enforcement personnel, we might as well invite our students to be "insiders". Once we find that the Internet cafe is operating illegally, we will give him a heavy penalty. I dare him to do it again.
Green Internet access also needs the guidance of teachers. Just like learning to swim, people who can't swim are flopping in the water, and those who can't surf the Internet just click. Time flies and the effect is poor. An hour later, they "choked" a few mouthfuls of water, and their minds were still blank.
It turned out to be a "gentle trap" set by following the mouse and the network, aimless. As a primary school student, my main task is to study, so I don't have so much time to surf the Internet for recreation. Therefore, the teacher's guidance is very important. I hope the school can strengthen the network construction, take more computer classes, and the teacher will tell us more about surfing the internet, so that we can make better use of the network to learn new knowledge.
Green Internet access will make children grow sturdily, and I believe that the Internet will become a fertile ground for students to grow faster and better.
5. Composition about Green Internet Access Now the Internet is becoming more and more popular, and today's society has entered the information age marked by the Internet. The internet has brought us a lot of convenience. We can check the information online and see the latest news; You can also broaden your horizons and promote learning. Our teachers also make full use of network resources and strive to improve our academic performance.
But the network is also a double-edged sword. Some students rely too much on computers, indulge in online games all day, miss classes, and their academic performance plummets; Some students have become prisoners of the network and become "small net worms"; Some students are nearsighted because their eyes are seriously damaged by watching computers all day; Even some students get addicted to the Internet all the time for playing games or chatting, which even leads to tragedy.
Wu Zhi, 17-year-old boy, first came into contact with computer games in an Internet cafe in 200 1 year, and then got out of hand. He developed from saving money by himself to asking for money on his own initiative and finally stealing money. On June 5th, 2004, Wu Zhi wanted to play games and asked his grandmother for money. She didn't agree, so he brutally killed his grandmother. A real thing happened in a county town recently. Because her parents were not at home, a girl surfed the Internet for four days and four nights and finally fainted in front of the computer. Fortunately, the rescue was timely and the tragedy was avoided.
At present, a large number of teenagers are surfing the Internet. Among the 26.5 million Internet users in China, teenagers under the age of 25 account for more than 85%, and they are doubling at an alarming rate every year. About two-thirds of these people surf the Internet in Internet cafes, and more than 99% of those who surf the Internet in Internet cafes are addicted to online games, which leads to the neglect of their studies and a bright future.
In my opinion, we students should study modern information technology and master basic computer skills. If possible, under the supervision and guidance of parents or teachers, you can surf the internet in moderation, so as to achieve five wants and five don't: be good at online learning and don't browse bad information; Honest and friendly, not insulting and deceiving others; To enhance self-protection awareness, don't date netizens at will; It is necessary to maintain network security without disturbing network order; It should be beneficial to physical and mental health, and we should not indulge in virtual time and space. But don't go to Internet cafes to surf the Internet. I believe that as long as you are successful in your studies, you will be able to surf the Internet in the future.
Therefore, I hope that students will stay away from Internet cafes and surf the Internet in a healthy and civilized way under the guidance of parents and teachers! Let the internet become a good helper for our growth, not a cancer that stifles our lives.
6. Green Internet constitutes green Internet access.
With the continuous development of the times, computers have become an indispensable tool in our lives. When we encounter problems in our study, we can find information online to solve the problems, so it is not convenient to go out. But when we need to go shopping, we can go to the online mall, and when parents miss their children who go out, we can video chat online. ...
The Internet has made our life so fast, convenient and colorful. Some teenagers surf the Internet not to study online, but to indulge in various online games. According to related reports, at about 6 am on September 15, 2002, when people woke up from their sleep and faced a new day and a new life, Zhang Xiaodong, a teenager who had been playing online games in Internet cafes all night, just stood up and suddenly shook his body. Another teenager on the side was busy helping him, but he couldn't help it. A young life just disappeared quietly.
This incident has sounded the alarm for teenagers' network security. Teenagers are addicted to online games, captured by the internet, do not study hard, are distracted and neglect their studies. What's more, teenagers are in the period of physical development. If they surf the Internet for a long time, not only will their eyes be nearsighted, but their spine will also be deformed and their health will be threatened ... Parents and teachers are making every effort to help students and children "quit" online games. Online games are too harmful, and it will harm our health after a long time.
Therefore, I call on the youth of the whole country to remember the Convention on Network Civilization:
1. Be good at online learning and don't browse bad information.
Be honest and friendly, don't insult and deceive others.
3. Enhance self-protection awareness, and don't date netizens at will.
4. Maintain network security and do not disturb network order.
5. It is good for physical and mental health, and don't indulge in virtual time and space.
I hope everyone can keep these five rules in mind and be civilized citizens.

8. I want to write a composition about green surfing, but I can't. Please give me a model essay. Thank you for your green surfing.
Nowadays, with the rapid development of information science and technology, all walks of life have set off an upsurge of computer networks. The era of network electronics has become a household name, and people are using the Internet more and more to obtain their own information. Our motherland is full of talents, and countless international students are far away in foreign countries. Why can I have the closest contact with my relatives? This is all because with computers, you can "contact" anytime and anywhere as long as you have chat software and audio-visual equipment. Look! There are many websites and columns on the Internet, such as news, finance, sports, education, mail, travel, real estate, shopping, books, constellations, music and so on. People can know what's going on in the world without leaving home, and they can know the local customs and surrounding environment without going to Wan Li Road. Do you think the Internet is like a universal doctor? Of course, there are gains and losses. Like the earth, the Internet has a sunny side and a dark and humid corner. Wrong information makes us go astray, yellow information makes us uncivilized, and we are "bosom friends" with ulterior motives. A school girl met a net friend while chatting online. The man claimed to "like her own sister" and they became "bosom friends" after a short contact. The girl saw him alone because she trusted this online "friend". I didn't know this "sister" was an adult man until we met. The girl regretted being cheated. The man's violent behavior caused serious trauma to the girl's mind. From this example, we can see that we can't trust netizens, otherwise it will only be self-defeating. When it comes to surfing the Internet and physical and mental health, some teenagers may think that surfing the Internet is just learning and communication, which has nothing to do with their own body and mind. No, this is closely related! If a person watches the computer for a long time, his eyes will be overtired. It is characterized by swelling and pain in the eyes, tears and severe headache. Therefore, we should arrange our time reasonably, and at the same time, we can surf the Internet as much as we like! The Internet is like an auditorium. Be polite at all times, don't insult others, and don't make fun of others with rude words. What's more, you must match your words with your deeds, and you can't break your word! Let's stop bad websites and accept the "education" of green websites!

10. Advocate green Internet access and enjoy healthy Internet access. Second, parents should study Internet knowledge hard, improve their Internet literacy, correctly guide their children to surf the Internet in a healthy and civilized way, actively participate in the activity of "purifying the Internet to protect their children-ten thousand mothers", and build their families into "gas stations" for teenagers to learn knowledge, so that they can become "protectors" for teenagers to prevent network injuries.
Third, school is the main channel for teenagers to learn network knowledge. We should vigorously popularize network knowledge, strengthen the ability to use the network, actively carry out network cultural activities that teenagers love and enjoy, and become a counseling base for cultivating young people to form a healthy network quality.
Fourth, telecom operators are the main body of Internet access services. They should actively use all kinds of technical means, actively filter all kinds of bad information, and carefully investigate websites with bad information such as obscenity, pornography and reactionary violence, so as to create a green grid space for the vast number of young people and stand the first post for their healthy growth.
Internet cafe is an important place for netizens to experience online life. It is necessary to strictly implement the Regulations on the Administration of Internet Service Sites and other national laws and regulations, resolutely reject pornography, gambling, drugs and other harmful information, give full play to its own network advantages, and become an important place to improve the network knowledge level of the whole people.
6. Internet site is an important garden for the construction of network civilization. It is necessary to strictly implement the Measures for the Administration of Internet Information Services and other national laws and regulations, vigorously carry forward the excellent culture of the Chinese nation, and carry forward the advanced network culture of patriotism and outstanding achievements of human civilization. Dedicate the best spiritual food to teenagers and show them the best spiritual world.
7. * * Relevant departments should conscientiously implement the spirit of a series of instructions of the Central Committee on purifying cyberspace and promoting network development, pay attention to prosperity on the one hand and management on the other, and comprehensively use economic means, legal means, administrative means and technical means to create a network to promote the healthy growth of young people.
Eight, social organizations should fulfill the responsibility of strengthening industry self-discipline and social supervision, integrate social resources, coordinate all forces, and work together to promote the formation of green grid space for teenagers.
