Problems solved by technology
[0004] Due to the overhead of a large amount of software processing, the traditional core-level communication protocol makes its users unable to obtain the communication performance that the underlying high-performance network hardware can provide.
Although the user-level communication protocol enables its users to obtain performance close to that provided by the underlying network hardware by reducing software overhead, it is ultimately limited by the performance of the computer network hardware.

Embodiment Construction
[0024] figure 1 A user-level parallel communication method between computers based on an intelligent network card. This method first fragments a large message, and the original message is divided into several small message fragments, and then the communication control module divides these messages in a round-robin manner. Fragments are distributed to multiple sets of networks in turn to achieve parallel transmission between different message fragments. Here, message fragmentation becomes the smallest unit of transmission for each network, and the message fragments of a certain message can be transmitted through multiple sets of networks at the same time.
[0025] The figure shows the core process of parallel communication on the parallel communication system composed of two sets of communication networks, where the arrows indicate the steps in the parallel communication process. A parallel communication process includes the following 9 steps:

A method for user-level parallel communication between computers, using multiple sets of high-performance networks that support smart network cards for interconnection between computers, and adding support to the operating system core space device driver and user space communication library that implements user-level communication protocols For parallel communication devices, data is automatically split and spliced among multiple sets of interconnection networks during transmission. The method can realize parallel, copy-free, and order-preserving message transmission between computers, and enables users to obtain the aggregation performance provided by multiple sets of interconnected network hardware. The method makes the parallel communication process transparent to the upper layer user and the lower layer communication network, and avoids increasing user burden and modification and dependence on a specific network. This method is suitable for systems where a single interconnection network cannot meet the performance requirements for inter-computer communication.
Description
technical field [0001] The invention relates to the technical field of parallel communication between computers, in particular to a method for user-level parallel communication between computers based on an intelligent network card. Background technique [0002] In recent years, although the growth rate of computer network bandwidth exceeds the processing capacity of processors, in many cases the communication performance of computer network is still the bottleneck restricting system performance, and the communication performance of a single network cannot meet the demand. At present, most of the super servers used in the world adopt a cluster structure, and present a large-scale symmetric multiprocessor (Symmetric Multiprocessor, SMP) or cache-related non-uniform memory access (Cache Coherent Non-uniform Memory Access, CC-NUMA). Even the trend of building fleets. In this type of system, a single set of high-performance Internet is difficult to meet the communication perfor...
