Structure of Dated
, , that to choose?

  Structure technical of Dated

1.
Principle: The model of architecture of the type “” is founded on the exploitation of several identical processors, working in parallel and sharing a common memory.

Disadvantages: Is the memory single, the synchronization of the access to the memory by the various processors is the main disadvantage of this type D? structure.

2.
Principle: The model of architecture of the type “” is founded on the exploitation of a big number of processors. Each processor has its own memory.
Disadvantage: Need for the specific developments. The processing must be provided for as of the design for an execution on this type of architecture.

3.  
Principle: With of the type “”, the computers are organized in “bunch”. They are inter-connected by fast connections Ethernet. On the plan of the principle, operation is rather close to architecture .
Disadvantage: Does the program to be carried out have imperatively to be developed for this type D? structure.

Recommendation

As for all information processing systems, the technical architecture of Dated will be chosen and dimensioned by taking account of volumetry, the number of users and the charge of potential activity.
Not easy to define for a project in continual development. Attention with under-dimensioning and do not hesitate to throw an eye over the achievements of competition.

Some manufacturers

This list is neither exhaustive, nor preferential

• a site manufacturer but having pitch badly of infos
  
• IBM the system of Went back to IBM
  
• acle 10g the system of Went back to Oracle
