Strict definition of distributed computing
Www.equn.com China Distributed Computing Terminal
Distributed computing is a split of engineering data that requires a large number of calculations into small pieces, calculated by multiple computers, and then uniformly consolidated the scientific conclusions after the upload operation result. At present, common distributed computing projects have idle computing capacity that usually use millions of volunteers around the world, data transmission is performed over the Internet. There is an analysis of the outdoor radio signal, thereby searching for the SETI @ Home project of the exterior life signs, the project data is large, more than 10 million digits, is currently the largest distributed computing project in the world, there have been 4 million The computer has joined this project (about 40,000 volunteers in mainland China); at the same time, there is also a Folding @ Home project that analyzes the internal structure of the protein and related drugs, which has approximately 100,000 supporters to participate in China (in mainland China About 60 volunteers). These projects are very large, needed to be amazing computational quantities, can't be done by a computer calculation. Even now there is a super computer with a superior computing power, some of the funds of some research institutions are very limited.
Distributed computing significance and pattern
Www.equn.com China Distributed Computing Terminal
First, distributed calculation and human
Due to the many research sciences of modern humans, the sort of sorting is involved. Every discipline today seems to be a large number of calculations. Astronomical Research Organization requires a computer to analyze space pulse, star movement; biologists need computer to simulate protein folding process; pharmacologists want to develop overcome AIDS or SARS (SARS) Drugs; mathematicians want to calculate more accurate values of maximum prime numbers and circumference; economists should use computer analysis to calculate tens of millions of factors to consider the development direction of a certain enterprise / city / country to macro regulation. It can be seen that the future of human future is not disconnected. Distributed Computing, with its unique advantages - cheap, efficient and more efficient and more receivable.

Second, messy distributed computing pattern
As far as it is, there are about 100 kinds of distributed computing around the world, which have no contacts, independent management, independently use their own software. This distributed computing pattern is very disadvantageous for development. For example, a biological research institution needs to utilize a computer from the world's volunteers to simulate the process of protein folding. The biological research institute has no professionals in distributed calculations, but in society, there is no company to offer this. Services, they have to spend a lot of energy for developing distributed computing servers, clients. In this way, it can be used to study the time of the biology to be used in other places. The biology research institution just mentioned is the Pande Group of Stanford University, USA.
Third, BOINC is a big overall situation, collaborate with each other!
In order to change this messy manner, the University of California, the University of California, first proposed the establishment of BOINC ideas. Boinc's Chinese is a Berkeley Open INFRASTRUCTRASTRUCTRURE for Network Computing, which can connect many different distributed computing projects. And unified allocation of computer resources (more interested in studying AIDS and exploring accessory civilization, you can choose two runs at the same time, and set priority). Unified management of statistical score systems (no matter which project you are working, as long as you dedicate your CPU time, you will be high). With such unified management, it is true that the Pande Group has facilitated scientific research institutions! Since Boinc is still in the test debugging phase, it should soon can appear in everyone's sight.

The simplest feet:

"Simplified Element" problem
For example, there is a 6 cm feet, we want the minimum number of scores, you can measure the integers of 1, 2, 3, 4, 5, and 6, how to do it? 1 cm and 4 cm, two lines, I will draw a simple map.
| __ | __ __ __ | __ __ | (vertical line indicates scores 0, 4, 6, each horizontal representation one centimeter)
I don't understand the 77th floor, I explain it, or that example
There are 6 horizontal lines in the example.
If you want to draw a straight line of 1 cm, use the first horizontal line;
If you want to draw a straight line of 2 cm long, use the last two horizontal lines;
If you want to draw a straight line of 3 cm long, use three horizontal lines;
If you want to paint 4 cm long straight line, use four horizontal lines on the left;
If you want to paint 5 cm long straight line, use five horizontal lines on the right;
If you want to draw a straight line of 6 cm long, use all six horizontal lines.
