Problems solved by technology

When a user accesses small-sized scattered data, a large number of network messages generated by the disk-oriented parallel I / O service method will make the network transmission cost far greater than the disk access cost, and network communication becomes a new bottleneck

Embodiment Construction

[0047] Figure 1 is a structural diagram of the current mainstream high-performance computer system parallel I / O system. Nodes in a high-performance computer system are divided into processing nodes (PN) and I / O nodes (ION) according to their main functions. The PN is mainly responsible for computing tasks, on which user applications run. PN sends I / O request to ION. ION has a disk and is mainly responsible for processing PN I / O requests. The parallel I / O structure of a high-performance computer system is divided into a centralized parallel I / O structure (as shown in Figure 1(a)) and a distributed parallel I / O structure (as shown in Figure 1(b) according to the relationship between ION and PN shown). In the centralized parallel I / O structure, PN does not have a disk and is only responsible for computing tasks; ION has a disk and is dedicated to I / O tasks without executing any user applications. ION and PN communicate through high-speed Internet to serve I / O requests from PN...

Abstract

The invention discloses a packet parallel I / O operation method facing to communication. It adds the communication packet structure and master node into computer system. It can get bigger bandwidth of accessing disc drive through synchronizing function of CIO operation interface, and make separate process for reading operation and writing operation. It adopts packet transmission method in both reading and writing operations.

Description

technical field [0001] The invention relates to the input / output technology in the computer field, that is, the I / O technology, especially the parallel I / O service method in the large-scale parallel processing system. Background technique [0002] Due to the unbalanced development between microprocessor technology and disk I / O technology, I / O has become one of the main bottlenecks restricting the overall performance of large-scale parallel computer systems. The use of parallel I / O technology is a way to alleviate this bottleneck. an important technical means. The large-scale parallel computer system distributes and stores files on the disks of multiple I / O nodes through the parallel file system, and provides high-performance parallel I / O through multiple I / O channels and parallel disk I / O services Serve. [0003] The current mainstream parallel I / O subsystem structure can be divided into centralized parallel I / O structure and distributed parallel I / O structure. Nodes in h...
