Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0024] In the present invention, "disposed on" or "attached to" is used to include a direct contact relationship with a single or multiple components. Moreover, the ordinal numbers used in the specification and claims, such as "first", "second", "number one" or "number two", are used to modify the components claimed for protection, which do not themselves contain and represent the Parts have any previous ordinal numbers, nor do they imply the order of one part with another or in terms of manufacturing methods, and these ordinal numbers are used only to enable a part with a certain designation to be related to another part with the same designation Can make a clear distinction. In a large-scale data processing environment...

Abstract

The invention discloses an astronomical data parallel processing device and method. The astronomical data parallel processing device comprises a computing cluster, wherein the computing cluster comprises a management server, a storage server and a plurality of computing servers; the storage server is used for storing a plurality of astronomical data files, parameter files and astronomical data processing instructions; and the astronomical data processing instructions are executed by the plurality of computing servers at the same time. The astronomical data parallel processing method comprisesthe steps that the management server operates a starting module; the starting module allocates the parallel modules to a plurality of computing servers for operation and allocates a task number to theastronomical data processing program; the parallel module starts an astronomical data processing program, extracts parameters from the parameter file in the storage server according to the task number and inputs the parameters into the astronomical data processing program; and the astronomical data processing program processes the astronomical data files in the storage server according to the parameters and stores results in the storage server.

Description

technical field [0001] The invention relates to the field of astronomical data processing, in particular to a device and method for parallel processing of astronomical data. Background technique [0002] With the continuous construction and precision upgrade of astronomical observation equipment, the ability to collect astronomical data has been greatly enhanced. Astronomical research has entered the era of big data. The original astronomical data processing program cannot meet the time requirements of big data processing. An essential tool for astronomical data processing. [0003] HPC (High Performance Computing System, high-performance computing system) is the main environment for parallel computing. Its core is composed of multiple computing servers with the same architecture, which form a computing cluster through a high-speed network, and then the computing tasks are distributed to different nodes by parallel processing software. Computing server, so as to realize the...
