Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The InfiniBand architecture is a "transition cable" technology that supports multiple concurrent links, each of which can run at 2.5Gbps. This architecture has a speed of 500MB / s for one link, 2GB / s for four links, and 6GB / s for 12 links. InfiniBand technology is not used for general network connections, and its main design purpose is for server-side connection problems. Therefore, InfiniBand technology will be applied between servers and servers (such as replication, distributed work, etc.), between servers and storage devices (such as SAN and direct storage attachments), and between se...

The invention relates to the field of a computer application technology and computer vision, in particular to a method for real-time scheduling of multiple high-precision three-dimensional scene data on the basis of InfiniBand. The method includes the steps that an RAID is established, an RAID cabinet is connected to a server through an RAID card, an InfiniBand network is set up by means of an InfiniBand network card and a network switch, the server serving as a node has access to the InfiniBand network, a terrain submodule is generated through terrain generation software and source data, and terrain is stored on the server; all prepared data, software and hardware are combined together to build a terrain server; an IG host has access to the InfiniBand network through the InfiniBand network card and optical fibers. According to the method, it is guaranteed that a system operates stably and efficiently, a data forecasting scheduling algorithm based on view frustums and time priorities is put forward on this basis, terrain data are scheduled and released in an internal storage according to view frustum culling prejudgment and existence time of data blocks in the internal storage, and therefore internal storage consumption of the system is reduced and data scheduling efficiency is improved.
Description
technical field [0001] The invention relates to the fields of computer application technology and computer vision, in particular to a method for real-time dispatching of massive amounts of high-precision three-dimensional scene data based on InfiniBand. Background technique [0002] In recent years, with the rapid development of the CPU as the core device of computer hardware, the gap between the computing power of the processor and the data scheduling efficiency of the memory is getting wider and wider, and this gap will continue to expand in the future. In order to reduce the impact on system performance caused by data transmission delay, most computers today adopt a hierarchical storage structure. The characteristics of this structure are: 1. The closer the memory is to the CPU, the smaller the storage capacity and the faster the data access speed; 2. When exchanging data between memories of different storage levels, data blocks can be used as the basic unit. Among them,...
