First, mathematical model
The model of the map spirit is modified: [1] has a recording strip with unlimited plurality of memory cells, and the change in content of each memory cell is limited, usually represented by binary "0" and "1", storage unit division Block organization; [2] Unlimited multiple reads and write heads with limited internal state, each read writing is responsible for a memory block. The read writing should be left or right on the record tape or not moving on the record tape. In operation, the map is read according to its internal state and the content of the current storage unit, and the contents of the internal state and the storage unit are changed according to the established rules. And determine the direction of movement of the writing head next step. [3] There is a function that can read the status of other read-write heads through this function. For more than half a century, mathematicians, computer scientists have proposed a variety of calculation models proved to be the same as the same map. This may be because they have the hardware level and network performance that have never been like today. Today, the network transmission bottleneck will gradually be broken, and the grid calculation will become the inevitability of computer history. It is appropriate to make it suitable for new computing modes. The above model may be called "grid map spirit".
Second, the program mode von. The program of the Nobiman structure uses the same memory, transmitted via the same bus, as shown below:
Von. Timing relationship between Nogan structural program
Harvard structure program directive flow timing relationship
The e-commerce grid platform uses Harvard structure program model. The compilation method of programming language is used to compile into Harvard structure mode.
The definition of object-oriented programming language (semantic) is the meaning of the various grammar components configured in object-oriented programming languages. Definition: General use of comparative natural language to describe. Formal method: Use mathematical symbols to be defined in a manner without ambiguous. Pseudo-compilation can make a translation, and run multiple times. Suitable for greater energy optimization work front end: Completion of analysis work (object analysis recognition) lexical analysis: Identify minimal grammar units. Grammatical analysis: Identify individual syntax structure. Semantic analysis: Determine type, type / operation legality check, identification meaning, and corresponding processing, static semantic check. Back end: Complete integrated work (unrelated compilation implementation machine independent) Optimization: Improve the quality of the target code. Target code generation
Third, the hierarchical structure creates a distributed application structure that is uninterrupted, uninterrupted, across the LAN, WAN, and Internet platforms to meet complex, evolving business needs. The structure that can be adapted to this environment is a grid computational hierarchical architecture. Grid computational hierarchical architecture can be better, multi-layer distributed structures, and more preferable information and more preferable Program execution performance. The following levels: data and program channel layers, hardware interface layers, asynchronous execution, and transmission control layers, data encryption layers, and corporate application layers. The hierarchical vertical direction generates the corresponding business functionality in the corresponding virtual device in the enterprise application layer.
IV. A major feature of safety model grid calculation is his openness, which is the security of this openness to the Internet. The security is a serious threat. In order to ensure that its healthy and orderly development must provide strong guarantees on cybersecurity. This platform provides end-to-end, enhanced authentication, integrity, and confidentiality.
5. Business model defines enterprise application logic as a virtual device.
Sixth, the profit model of software license software depends on the use of business and individual to virtual equipment, suitable for many varieties of small sales volume.
Seven, this system advantage This system platform can easily realize enterprise-class applications such as e-commerce applications, distributed search engines. At the same time, you can give full play to the efficiency of the hardware system.
Flexibility This system provides a functional extension through virtual equipment, itself has a lot of flexibility.
Eight, external expressions of e-commerce grid platform and development tools, grid browser.
