内容記述 | 月探査衛星かぐやで観測した電界波形データには, 特徴的なバイポーラ型波形が多数確認されている. このバイポーラ型波形を観測データから自動抽出し, 波形の特性を求めるアルゴリズムを開発中であるが, 観測データの総容量が約190GBにも及ぶため, 情報通信研究機構(NICT)のサイエンスクラウド上でPwrakeを用いて並列処理による高速化を図った. 本論文では効率を評価した結果を報告する. Characteristic bipolar waveforms were frequently observed by the electric waveform receiver onboard the lunar orbiter named KAGUYA. An algorithm to extract these bipolar waveforms is now under development, but the total amount of the waveform data is about 190GB and it is too huge to apply the algorithm on a general PC workstation. In the present study, we attempt to accelerate computation time by a parallel and distributed workflow named “Pwrake” implemented on NICT science cloud. We report the evaluation results of the efficiency of the data processing. | |||||
