Korrekturlesen

  • Hallo,


    jetzt bräuchte ich mal ein Sprachgenie, welches mir meinen Text auf Fehler untersucht. Der Text lässt sich vielleicht etwas blöde lesen. Es handelt sich dabei um einen Ausschnitt aus einem Vortrag über verteiltes Rechnen. Mir kommt es hauptsächlich auf die Grammatik an.
    So, ich geh' dann schon mal in Deckung, wenn man mir nachher all meine Fehler vorhalten wird...



    What is this? This is not only the Central Processing Unit of a Computer. It is more. It is the answer to mathematical problems. It would be able to find a drug against cancer oder malaria and it helps to find extraterrestrial life. And how? Only with Distributed Computing. And everybody can take a part in this.
    Nowad ays Computers are used to aid scientists in their research. But sometimes, for example in the climate prediction or in the search to find a drug against diseases, the computation needs too much time. Not hours or days. No. Weeks, months and sometimes years. The answer for this problems are supercomputers, which are able to compute the problems in some days or weeks. They consist of thousands of such CPU's but these computers are very expensive, and research establishments without additional subsidy can't buy or lease such a computer.
    The Idea is now to fractionise the large problem into subproblems and to compute the subproblems with personal computers. But research establishments can't buy hundreds or thousands of personal computers, either, but nearly in every household there is to find a personal computer. And everybody can take a part in the support of research at home. Only a computer with access to the Internet is needed The subproblems are stored on a Server. You have only to download a client. The client computes the subproblems in some hours, days or sometimes weeks, and manages the download of subproblems and the upload of computed subproblems via the Internet.This process is called "distributed computing". The client uses the unused reso urces of the computer which are not in use at the moment. And the user does not notice the fact that his computer supports the research while he is writing a letter or playing a game. The access is for free, and the user makes his computer work for free. The computed subproblems are recomposed by the scientists and the answer falls in place with the many litte answers to the subproblems.
    And there are a lot of advantages of distributed computing. At first it is cheaper for research etablishments to develop a newly distributed computing project than to lease or buy a supercomputer. And second, distributed computing would be faster than a supercomputer, if enough people allow the use of their computers for such a project. And there are many more advantages. The fastest supercomputer, called "Earth Simulater", is 50 meters in length, 65 meters in width and 17 meters in height With distributed computing such a great(?) area, for example a separate building only for the computer, is not needed And Earth Simulater needs 6.4 MegaWatt per hour. But a personal computer doesn't need much more electric current while he is computing a workunit of a distributed computing project. But there are no advantages without disadvantages. A problem is the possibility of losing a workunit during the data communication between PC and Server. Also every subproblem has to be sent out several times by the Server to avoid the loss. And it is a little bit problematic to find people who want to have their PC computed for a distributed computing project. To counteract this fact, many teams were founded by enthusiastic people dealing with distributed computing, to represent their country in the statistics and to gain new members. The best-known team of Germany is rechenkraft.net. One of the most successfully distributed computing projects is "Find a Drug". It was founded by the Oxford University in collaboration with a well known producer of computers. This project is used to find new drugs against Cancer, Malaria, Multiple Sclerosis, HIV and many more. More than 10000 people of 69 contries are members of this project....
