Embodiment 1

[0031] The invention proposes a novel hierarchical control HPCS based on OPS and optical multicast. Taking two-level HPCS as an example, the first level is defined as the master node, and the second level is the slave node. The master node has n slave nodes; each slave node has m CPUs. The master node has the highest management level, manages and controls n slave nodes, and the slave nodes manage their own m CPUs, and so on, which can achieve multi-level expansion. Define the signal forwarded from the slave node to the master node as an uplink signal, and the signal forwarded from the master node to the slave node as a downlink signal.

[0032] The signals generated by the m CPUs of each slave node are connected to the switching unit of the slave node through Dense Wavelength Division Multiplexing (DWDM) technology, and similarly, the signals generated by n slave nodes are connected to the master node through DWDM technology.

[0033] Through the control channel, the CPUs re...

Abstract

The present invention discloses a grading control computer system based on the optical packet switch and optical multicast, including at least two groups of CPUs (A), and optical interconnection switching devices linked between the CPUs (A). The optical interconnection switching devices include at least a first level node (1) and a second level node (2). The current HPCS usaully takes use of the centralized control mode: each port has to send the request signals to a central dispatcher after it generates a business, and if the distance is longer, it may introduce a trip delay having a larger request and answer signal. The present invention adopts a grading controlled management style, in which the node is only needed sent requests to the local control unit, thus it can greatly reduce such delay, and at the same time, can reduce the storage and computing pressure of each level control unit.

Description

technical field [0001] The invention relates to a hierarchical control computer, in particular to a hierarchical control computer system based on optical packet switching and optical multicasting. Background technique [0002] In the past few years, in the field of technology, the development of computing resources often cannot keep up with the needs of applications. In some specialized fields such as quantum physics experiments and global climate simulations, it is necessary to share a large amount of measurement data to strengthen the ability of analysis and calculation. At the same time, in order to meet the needs of industries and fields such as scientific research, resource environment, manufacturing and service industries, it is hoped to develop a number of large-scale application systems based on high-performance computing and grid technology to realize resource sharing and collaboration in industries and fields Work, improve the productivity of the industry, and pro...
