Embodiment Construction
[0020] A cluster communication model based on address mapping of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] Such as figure 1 As shown, a high-speed communication model in the structure of a cluster communication model based on address mapping of the present invention is as follows figure 1 As shown, different nodes in the cluster are connected to each other through a memory address mapping device. Each host opens up a section of space in its own memory as the memory access area of other nodes. For sending and receiving data.
[0022] The memory address mapping device (such as NTB, the NTB temporary memory address mapping device is used in the following chapters of this article), can realize memory access between different host systems, and realize the purpose of communication through interrupt registers and temporary registers. Through address translation technology, a section of memory in the local mach...

The invention provides a trunking communication model based on address mapping. The trunking communication model is composed of a plurality of mainframe systems and a plurality of communication modules, wherein the plurality of mainframe systems respectively include a memory address mapping device and a communication module based on memory address mapping, and the memory address mapping device is used for performing memory address mapping among different mainframe systems; compared with the prior art, the trunking communication model based on address mapping achieves RDMA based on memory address mapping, is packaged according to a special communication protocol, directly achieves package forwarding at the communication modules, achieves zero-copy data transmission, fully utilizes physical transmission links among computer mainframes, and achieves improved transmission performance and reduced system losses; the trunking communication model based on address mapping achieves memory address mapping and data transmission based on NTB, and transmits data by using a PCI-E2.0 protocol, thus having good popularization and application values.
Description
technical field [0001] The invention relates to the field of computer cluster system and storage, in particular to a cluster communication model based on address mapping. Background technique [0002] A computer cluster is a computer system that is connected by a group of loosely integrated computer software and / or hardware to perform computing tasks in a highly co-operative manner. In a sense, they can be seen as a computer. The individual computers in a cluster system are usually called nodes and are usually connected by a local area network, but there are other possible connections. Cluster computers are often used to improve the computing speed and / or reliability of individual computers. In general, cluster computers are much more cost-effective than individual computers, such as workstations or supercomputers. [0003] The starting point of computer cluster technology is to provide computer systems with higher availability, manageability, and scalability. A cluster ...
