Effective system for simulating dust continuum observations on distributed computing resources 本山, 一隆 田中, 義一 合田, 憲人 坂根, 栄作 三浦, 謙一 Motoyama, Kazutaka Tanaka, Yoshikazu Aida, Kento Sakane, Eisaku Miura, Kenichi distributed computing radiative transfer scientific workflow We present an effective system for simulating dust continuum observations by radiative transfer simulations. By using workflow management system RENKEI-WFT, we utilized distributed computing resources and automated a sequence of computational tasks required for radiative transfer modeling, namely, main radiative transfer simulations, pre-/post-processes, and data transfer between computing resources. Our system simultaneously executes a lot of radiative transfer simulations with different input parameters on distributed computing resources. This capability of our system enables us to conduct effective research by radiative transfer simulation. As a demonstration of our system, we simulated dust continuum observations of protoplanetary disk. We performed hydrodynamic simulation modeling photoevaporating protoplanetary disk irradiated by ultra violet radiation from nearby massive stars. Results of this hydrodynamic simulation were used as input data for radiative transfer simulations. Expected spectral energy distributions and intensity maps were obtained by our system. 資料番号: AA0062302017 レポート番号: JAXA-RR-13-010 technical report 宇宙航空研究開発機構(JAXA) Japan Aerospace Exploration Agency (JAXA) 2014-03-31 application/pdf 宇宙航空研究開発機構研究開発報告: 宇宙科学情報解析論文誌: 第3号 JAXA-RR-13-010 155 161 JAXA Research and Development Report: Journal of Space Science Informatics Japan: Volume 3 1349-1113 AA1192675X https://jaxa.repo.nii.ac.jp/record/1967/files/62302017.pdf https://jaxa.repo.nii.ac.jp/records/1967 eng
