In the proposed method, the message passing interface (MPI) is used to connect each core-group (CG) and the registor level massaging passing interface (RL-MPI) is used to connect the slave core on each computing processing element (CPE) cluster, which efficiently overcomes the bottleneck caused by discrete memory accessing. Numerical results show that the performance of DGTD on SW26010 CPU can be dramatically improved by using RL-MPI.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"461 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114417370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various different ground plane sizes that can cover almost all the current portable devices such as mobile phone, PAD, tablet and notebook computer are considered. The variation trend between the ground plane size and the antenna bandwidth potential clearly demonstrates how the ground plane size affects the performance of the LTE antenna. The conclusion drawn in this work is confirmed by a real LTE antenna design and the LTE antenna designs reported in the literature.","PeriodicalId":198124,"journal":{"name":"2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114418494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
