Electromagnetic scattering calculation usually has the characteristics of large-scale calculation, high space-time complexity, and high precision requirement. For the background and objectives of complex environment, it is difficult for a single computer to achieve large-scale electromagnetic scattering calculation and to obtain corresponding large data. Therefore, we use Finite-Difference Time-Domain (FDTD) combined with Internet of Things, cloud computing, and other technologies to solve the above problems. In this paper, we focus on the FDTD method and use it to simulate electromagnetic scattering of electrically large objects. FDTD method has natural parallelism. A computing network cluster based on MPI is constructed. POSIX (Portable Operating System Interface of UNIX) multithreading technology is conducive to enhancing the computing power of multicore CPU and to realize multiprocessor multithreading hybrid parallel FDTD. For two-dimension CPU and memory resources, the Dominant Resource Fairness (DRF) algorithm is used to achieve load balancing scheduling, which guarantees the computing performance. The experimental results show that the hybrid parallel FDTD algorithm combined with load balancing scheduling can solve the problem of low computational efficiency and improve the success rate of task execution.<\/jats:p>","DOI":"10.1155\/2019\/7309431","type":"journal-article","created":{"date-parts":[[2019,6,23]],"date-time":"2019-06-23T19:33:28Z","timestamp":1561318408000},"page":"1-9","source":"Crossref","is-referenced-by-count":1,"title":["Hybrid Parallel FDTD Calculation Method Based on MPI for Electrically Large Objects"],"prefix":"10.1155","volume":"2019","author":[{"given":"Qingwu","family":"Shi","sequence":"first","affiliation":[{"name":"Department of Information Engineering, School of Electronics and Information Engineering, Harbin Institute of Technology, Harbin 150001, China"},{"name":"College of Information Science & Electronic Technique, Jiamusi University, Jiamusi 15407, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6135-3174","authenticated-orcid":true,"given":"Bin","family":"Zou","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, School of Electronics and Information Engineering, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3595-0001","authenticated-orcid":true,"given":"Lamei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, School of Electronics and Information Engineering, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Desheng","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Information Science & Electronic Technique, Jiamusi University, Jiamusi 15407, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2019.04.048"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s10878-015-9847-0"},{"volume":"28","journal-title":"Journal of Telemetry, Tracking and Command","year":"2007","key":"3"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/TSC.2018.2867482"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2018.2791424"},{"issue":"2","key":"6","doi-asserted-by":"crossref","first-page":"790","DOI":"10.1109\/TII.2017.2739340","volume":"14","year":"2018","journal-title":"IEEE Transactions on Industrial Informatics"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2018.2871084"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2018.2808910"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.2018.1800078"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/MAP.2011.6028417"},{"year":"2011","key":"12"},{"year":"2001","key":"13"},{"issue":"5","key":"14","first-page":"133","volume":"20","year":"2010","journal-title":"Computer Technology and Development"},{"year":"2011","key":"15"},{"issue":"5-3","key":"16","first-page":"226","volume":"23","year":"2007","journal-title":"Microcomputer Information"},{"year":"2011","key":"17"},{"year":"2014","key":"18"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/7309431.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/7309431.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/7309431.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T12:46:20Z","timestamp":1569242780000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2019\/7309431\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,23]]},"references-count":17,"alternative-id":["7309431","7309431"],"URL":"https:\/\/doi.org\/10.1155\/2019\/7309431","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2019,6,23]]}}}
