This paper shows how \"intelligent communication controllers\" (ICCs) help to reduce the immense communication overhead and accumulated latencies to an absolute minimum. Three examples of \"intelligent\" communication schemes are presented: the fully automatic redistribution of multi-dimensional data sets, depthmerge and bucket-sort. We show that these (and other) \"intelligent communication schemes\" can be implemented in hardware with a reasonable effort and that the communication bandwidth is used most efficiently. This results in a good speed-up, good scalability and the maximum utilizable performance for parallel rendering and many other data-parallel algorithms running on our multiprocessor system \"MUSIC\". As an example, we present a simple objectparallel renderer running at interactive frame rates.","PeriodicalId":101947,"journal":{"name":"Proceedings of the IEEE symposium on Parallel rendering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128991118","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}

Volume visualization of such data is a challenging problem. This paper proposes a distributed parallel solution that makes ray-casting volume rendering of unstructured-grid data practical. Both the data and the rendering process are distributed among processors. At each processor, ray-casting of local data is performed independent of the other processors. The global image compositing processes, which require inter-processor communication, are overlapped with the local ray-casting processes to achieve maximum parallel efficiency. This algorithm differs from previous ones in four ways: it is completely distributed, less view-dependent, reasonably scalable, and flexible. Without using dynamic load balancing, test results on the Intel Paragon using from two to 128 processors show, on average, about 60% parallel efficiency.","PeriodicalId":101947,"journal":{"name":"Proceedings of the IEEE symposium on Parallel rendering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116536944","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}
