AI Technical Summary

Problems solved by technology

However, in the fully connected system, the cost of cables for connecting each information processing device increases, and problems such as complicated cable routing are conceivable.
Therefore, it is considered difficult to apply the full connection method to a system with a large number of information processing devices

Embodiment Construction

[0045] figure 1 is an overall configuration diagram of the information processing system in Embodiment 1. exist figure 1 In , the information processing system has a topology in which nodes N are connected to form a 2-dimensional ring. which is figure 1 In , the nodes located at the left and right ends are respectively connected by the same numbers of (0), (1), ..., (5). Likewise, the nodes located at the upper and lower ends are respectively connected by the same numbers of (10), (11), . . . , (15). As a result, each node is connected in a two-dimensional ring.

[0046] Here, each node N is an information processing device. exist figure 1 In the configuration example of , there are 6 nodes N arranged in the + / -x direction (horizontal direction in the figure), and 6 nodes are arranged in the + / -y direction (vertical direction in the figure), for a total of 36 nodes N. In addition, in figure 1 Among them, the right direction is the +x direction, and the down direction i...

Abstract

In an information processing system including information processing devices multi-dimensionally connected with one another, each of the information processing devices compares a position of a destination information processing device in a dimension to which data are transmitted with a position of an own information processing device in the same dimension, and if the position of the own information processing device matches a position one information processing device before the destination information processing device as a result of the comparison, controls the virtual channel to which the data are allocated such that the virtual channel is changed to another one.

Description

technical field [0001] The present invention relates to an information processing system, for example, an information processing system in which a plurality of information processing devices are multi-dimensionally connected to each other, an information processing device, a control method of an information processing device, a control program of an information processing device, and a computer-readable recording medium storing the control program. Background technique [0002] An information processing system in which a plurality of information processing devices are connected to each other is called a parallel computer system. In a parallel computer system, as a network connecting multiple information processing devices, one of the most ideal ways is a one-to-one connection between each information processing device and all other information processing devices on the system, which is called full connection (full connection). connection) way. However, in the fully-connecte...
