Abstract

The invention provides a high-performance parallel computing method based on external PCI-E connection. The method includes the steps of (a) connecting all pieces of computer equipment through a PCI-E bus, (b) running a parallel computing program, (c) constructing a virtual memory addressing table, (d) sending virtual memory information, (e) receiving the virtual memory information, (f) judging correctness of the received information, (g) judging whether a virtual memory address is constructed, (h) allocating computing tasks, (i) executing the computing tasks, and (j) obtaining results and providing the results for a user. The data transmission speed between processors is increased in the parallel computing process through the parallel computing method; the parallel computing method is improved, so that the copy data size of a system CPU is reduced, efficiency of parallel computing operation is greatly improved, multiple parallel computing resources are effectively connected for communication, and data are transmitted at a high speed.

Description

technical field [0001] The invention relates to a parallel computing method, more specifically, to a high-performance parallel computing method based on an external PCI-E connection. Background technique [0002] Parallel computing refers to the process of using multiple computing resources to solve computing problems, which can improve the computing speed and processing capacity of the computer system. Generally, multiple processors are used to jointly calculate and solve the same problem, and the problem is decomposed into several parts. Each part Parallel computing is performed by separate processors, and multiple processors are connected in a certain way to form cluster computing resources. After the cluster computing resources complete data processing, the calculation results are fed back to the user. [0003] At present, most of the multi-processor connection methods for parallel settlement are carried out by network connection, that is, by using a computer network car...
