Problems solved by technology

[0003] At present, deGridding uses serial processing to process data. Since serial processing is used, that is, a single thread is used to process the data in each cycle one by one, the speed of processing data is too slow, which consumes a lot of time and the utilization of cache space. lower

Abstract

The invention discloses a processing method used for radio astronomy data. Firstly, a target data amount and the number of preset threads are obtained; then the target data amount is divided to obtaina plurality of target data blocks; and finally, the target data blocks are allocated for all threads by a predefined rule to enable all the threads to carry out simultaneous calculation of the targetdata amount. Therefore, in the scheme, the target data amount is divided, and then allocated to the multiple threads for simultaneous processing, the method greatly reduces time, which is required for calculation of the data amount, as compared with a manner of using a single thread for processing on the target data amount in the prior art, at the same time, the target data can be processed quickly, thus it is guaranteed that cache space thereof can be released as soon as possible, and a utilization rate of the cache space is improved. In addition, the invention also discloses processing devices used for the radio astronomy data and a storage medium, of which effects are as above.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a processing method, device and storage medium for radio astronomical data. Background technique [0002] The Square Kilometer Array Astronomical Telescope is the largest synthetic aperture radio astronomical telescope currently under construction in the world. It has multiple intermediate-frequency and low-frequency aperture arrays and is currently distributed in Australia, South Africa, the Netherlands and other countries. The total area is about 1 square kilometer, hence the name "square kilometer array". Among them, deGridding is the data processing link in the square kilometer array astronomical telescope, and 30% of the astronomical data in the entire astronomical telescope needs to be processed by deGridding. Among them, the calculation core of deGridding mainly includes three calculation loops, the outermost loop is the "visual point" calculation loop, and the calculat...
