Abstract

The invention discloses a data processing method and device for radioastronomy data, wherein the data processing method comprises an outermost layer circulation processing process, a middle layer circulation processing process and an innermost layer circulation processing process. The method comprises the following step of allocating the calculation quantity of each time of iteration in the outermost layer circulation processing process to different threads, wherein each thread uses a vectorization instruction. According to the embodiment, a multi-thread task schedule method is used for allocating the calculation quantity of each time of iteration; the load calculation balance performance of each thread is improved; the deGridding is subjected to efficient optimization; and the performanceis greatly improved.

Description

technical field

[0001] The invention belongs to the field of computers, in particular to a data processing method and device for radio astronomy data. Background technique

[0002] The international astronomical project "Square Kilometer Array" astronomical telescope (SKA, Square Kilometer Array). This project aims to build the world's largest synthetic aperture radio astronomy telescope. It has 3000 parabolic dish antennas with a diameter of 15 meters and 250 sets of intermediate frequency and low frequency aperture arrays. The distribution range is greater than 3000 kilometers. The sensitivity of the currently largest radio telescope array (JVLA) has been increased by about 50 times, which is about 10,000 times higher than that of my country's current largest single-aperture radio telescope (FAST). According to the plan, the amount of data collected by SKA per second is greater than 12Tb, which requires the sum of the performance of almost all supercomputers in the TOP500 ...
