【摘要】:天文學(xué)研究中經(jīng)常需要通過交叉證認(rèn)將來自多波段多項目天文數(shù)據(jù)聯(lián)系起來統(tǒng)一考慮.當(dāng)前天文數(shù)據(jù)急劇增長,必然導(dǎo)致交叉證認(rèn)的速度過慢.針對這一問題,提出一種在多核環(huán)境下使用Python語言進(jìn)行高效并行計算的方法,與以往的研究結(jié)果相比,速度提高了若干倍.這為下一步的多波段數(shù)據(jù)統(tǒng)計研究和數(shù)據(jù)挖掘打下了良好的基礎(chǔ).
[Abstract]:In astronomical research, cross-validation is often needed to link multi-band and multi-project astronomical data together. The rapid growth of astronomical data is bound to cause the speed of cross-identification to be too slow. In order to solve this problem, an efficient parallel computing method using Python language in multi-core environment is proposed. Compared with the previous research results, the speed is several times faster. This lays a good foundation for the next multi-band data statistics research and data mining.
