[0044] Example:

[0045] like Figure 1-Figure 5 As shown, in a first aspect, an embodiment of the present invention provides a multi-layer message mechanism distributed cluster communication management method, comprising the following steps:

[0046] S1. Build a multi-layer message ring;

[0047] Further, based on the first aspect, in some embodiments of the present invention, the multi-layer message ring includes a first-layer message ring, a second-layer message ring and a third-layer message ring, wherein:

[0048] The first-layer message ring includes service control information, which is used in conjunction with the MPI distributed computing model; the second-layer message ring includes routing information and triggering information, which is used to complete the routing forwarding of signaling, the triggering and synchronization of the working sequence between low-level execution modules; the third-layer message ring has timing characteristics, which is used to realize the working sequence and resource management within the low-level execution module. The low-level execution module includes an instruction executor, an execution management unit, a computing unit, a transmission unit, etc.

[0049] In some embodiments of the present invention, the first-layer message ring: a variable-length message ring, which has certain business control information inside and can be used in conjunction with the MPI distributed computing model. For example, for a multi-server cluster system using multi-layer messages, the cluster system is composed of traditional servers and slave device ends, and has the characteristics of multi-tasking. Assuming that there are multiple tasks (a single task corresponds to a process) in the current multi-server cluster system. Data transmission or communication between, the message protocol package of the first-layer message ring can be applied to both traditional servers (dimensional transmission) and between traditional servers and slave device ends (longitude transmission).

[0050] For the multi-tasking of traditional servers, the processing function of the first-layer message ring will call the MPI distributed computing model interface for transmission processing;

[0051] For the use of traditional servers and slave devices in conjunction, in addition to the above transmission, message transmission between the traditional server and the slave device is also added.

[0052] The second layer message ring: has routing information, source address and destination address information, and control information (trigger type and semaphore type), which can complete the routing forwarding of signaling and combine with the third layer message ring to realize the triggering and synchronization of the working sequence between low-level execution modules.

[0053] The third-level message ring has a more compact timing feature and provides synchronization and mutual exclusion features. The third-level message package contains the executor status, mutex address and type, and data flow information. Using the above information, the internal working timing and resource management of the low-level execution module can be realized. Through the executor status and mutex, the start, wait, and stop states of the corresponding processing unit can be controlled to complete the control of the working timing of the low-level execution module; combined with the data flow information, the communication transmission process can also be controlled, thereby realizing the resource scheduling of multiple tasks (a single task occupies multiple execution bodies).

[0054] Further, based on the first aspect, in some embodiments of the present invention, the multi-layer message mechanism distributed cluster communication management method further includes the following steps: performing longitude signaling transmission between message rings of each layer.

[0055] Further, based on the first aspect, in some embodiments of the present invention, the multi-layer message mechanism distributed cluster communication management method further includes the following steps: dimensional message transmission is performed within each layer of the message ring.

[0056] The message ring is divided into three layers, including the first layer message ring, the second layer message ring and the third layer message ring, which have the following characteristics:

[0057] Messages can be transmitted between the first-layer message ring, the second-layer message ring and the third-layer message ring, which is called longitude signaling transmission.

[0058] Message passing within the first-layer message ring, message passing within the second-layer message ring, and message passing within the third-layer message ring are called: dimensional message passing.

[0059] The message rings at each layer are interrelated, mainly including the relationship between the content formats of the protocol packets at each layer and the logical relationship between the data transmission at each layer, including:

[0060] The relationship between protocol packets at each layer: the signaling content of the first layer message is the second layer message packet, and the message content of the second layer message is the third layer message packet.

[0061] Each layer of message ring performs logical association for data transmission, such as Figure 3 As shown, including:

[0062] A1. The first-layer message packet enters the dimension judgment step: judge whether the first-layer message packet is dimension transmission, if yes, enter the first-layer message loop for transmission, otherwise, enter the longitude transmission, enter the second-layer message loop, and execute step A2;

[0063] A2, the second layer message packet enters the dimension judgment step: judge whether the second layer message packet is dimension transmission, if so, enter the second layer message ring for transmission, otherwise, enter the longitude transmission and enter the third layer message ring;

[0064] A3. Entering the third layer message ring, it is transmitted to the final processing unit.

[0065] S2. Acquire and use each layer of message rings according to the preset message ring transmission packet protocols of each layer to transmit messages between the working nodes in the distributed cluster according to the task requirements.

[0066] Further, as shown in Table 1 (Table 1 is the first layer message ring transmission packet protocol), based on the first aspect, in some embodiments of the present invention, the first layer message ring transmission packet protocol in the above-mentioned preset message ring transmission packet protocols of each layer includes a frame header, a valid communication byte, a spare code, a protocol type, a default code, a data type, a request ID+communication type, a signaling content, a checksum high eight bits, a checksum middle eight bits, a checksum eighth bit, and a frame tail.

[0068]

[0069] Furthermore, if Figure 4 As shown, based on the first aspect, in some embodiments of the present invention, the second layer message ring transmission packet protocol in the above-mentioned preset message ring transmission packet protocols includes CRC check, signaling and packet header, routing, source address, destination ID, trigger type and semaphore type.

[0070] Furthermore, if Figure 5 As shown, based on the first aspect, in some embodiments of the present invention, the third layer message ring transmission packet protocol in the above-mentioned preset message ring transmission packet protocols includes CRC check, signaling + data flow information and packet header, source address, destination ID, executor status, mutex address and mutex type.

[0071] In some embodiments of the present invention, after the corresponding multi-layer message ring is constructed, each distributed cluster storage computing node uses the above-constructed message rings to transmit different data, and the message rings of different levels in each cluster correspond to each other, and transmit different data in a targeted manner. The message rings of each layer in each cluster can also transmit data to each other. The three-layer message ring constructed based on the present invention is associated with each other, and each layer of the message ring can also transmit data independently, so as to realize the efficient transmission of messages of each working node of the distributed cluster.

[0072] In order to solve the problems in the prior art, the present invention adopts a multi-layer message ring mechanism to transmit messages between distributed cluster storage computing nodes, which greatly improves the transmission efficiency.

The present invention adopts a hierarchical message mechanism, the multi-layer message ring protocol is clearly decoupled, the message package protocols at each level are rich, and the message rings also complete signal transmission with each other, which solves the problem of multiple message layers in distributed clusters (the division of multiple message layers is unclear, and the problem of mutual invasion of message layers), greatly improves the transmission efficiency of distributed cluster messages, and constructs a cluster solution based on a message mechanism.

[0073] like Figure 6As shown, in a second aspect, an embodiment of the present invention provides a multi-layer message mechanism distributed cluster communication management system, including: a multi-layer construction module 100 and a hierarchical transmission module 200, wherein:

[0074] A multi-layer construction module 100 is used to construct a multi-layer message ring;

[0075] The hierarchical transmission module 200 is used to obtain and use each layer of message rings according to the preset message ring transmission packet protocols of each layer to transmit messages between the working nodes in the distributed cluster according to the task requirements.

[0076] In order to solve the problems in the prior art, the system builds a multi-layer message ring through the cooperation of a multi-layer construction module 100 and a hierarchical transmission module 200, and then transmits messages between different message rings based on the preset message ring transmission packet protocol of each layer in combination with different task requirements.

The independence and decoupling of individual layer message rings; the hierarchical message ring combines messages and data according to requirements; the present invention realizes efficient transmission of cluster messages. With a clearly hierarchical message mechanism, signal transmission can be completed between message rings, which solves the problem of multiple message layers in distributed clusters, greatly improves the efficiency of distributed cluster message transmission, and constructs a cluster solution based on a message mechanism.
