The SuperB project plans to produce and analyzes bulk of dataset two times bigger than the actual HEP experiment. In this scenario one of the main issues is to create a new cluster setup, able to scale for the next ten years and to take advantage from the new fabric technologies, included multicore and graphic programming units (GPUs). In this paper we propose a new site-wide cluster setup for Tier1 computer facilities, aimed to integrate storage and computing resources through a mix of high density storage solutions, cluster file system and Nx10Gbit/s network interfaces. The main idea is overcome the bottleneck due to the storage-computing decoupling through a scalable model composed by nodes with many cores and several disks in JBOD configuration. Preliminary tests made on 10Gbit/s cluster with a real SuperB use case, show the validity of our approach.","PeriodicalId":167131,"journal":{"name":"2011 First International Conference on Data Compression, Communications and Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125806623","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}

Co Tracks algorithm has been projected for a lossy compression of GPS data, exploiting analogies between all their spatio-temporal features. The original contribution of this algorithm is the consideration of the altitude of the track, an elaboration of 3D data and a dynamic vision of the moving point, because the speed, tightly linked to the time, is supposed to be one of the significant parameters in the uniformity search. Minimum Bounding Box has been the tool employed to group data points and to generate the key points of the approximated trajectory. The compression ratio, resulting also after a further Huffman coding, appears attractively high, suggesting new interesting developments of this new technique.","PeriodicalId":167131,"journal":{"name":"2011 First International Conference on Data Compression, Communications and Processing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114504084","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}

Cache Friendly Burrows-Wheeler Inversion 缓存友好的陋居-惠勒反转

Inversion of the transform is a bottleneck in practice. Inversion takes linear time, but, for each symbol decoded, folklore says that a random access into the transformed string (and so a CPU cache-miss) is necessary. In this paper we show how to mitigate cache misses and so speed inversion. Our main idea is to modify the standard inversion algorithm to detect and record repeated sub strings in the original string as it is recovered. Subsequent occurrences of these repetitions are then copied in a cache friendly way from the already recovered portion of the string, short cutting a series of random accesses by the standard inversion algorithm. We show experimentally that this approach leads to faster runtimes in general, and can drastically reduce inversion time for highly repetitive data.","PeriodicalId":167131,"journal":{"name":"2011 First International Conference on Data Compression, Communications and Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125845245","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}

We will here show how Catalog a can be used to achieve efficient data mining and information retrieval by means of lexical ontology associated to terminology-based automatic textual analysis. Also, we will show how accurate data compression is necessary to build efficient textual analysis software. Therefore, we will here discuss the creation and functioning of a software for semantic-based terminological data mining, in which a crucial role is played by Italian simple and compound-word electronic dictionaries. Lexicon-Grammar is one of the most profitable and consistent methods for natural language formalization and automatic textual analysis it was set up by French linguist Maurice Gross during the '60s, and subsequently developed for and applied to Italian by Annibale Elia, Emilio D'Agostino and Maurizio Martin Elli. Basically, Lexicon-Grammar establishes morph syntactic and statistical sets of analytic rules to read and parse large textual corpora. The analytical procedure here described will prove itself appropriate for any type of digitalized text, and will represent a relevant support for the building and implementing of Semantic Web (SW) interactive platforms.","PeriodicalId":167131,"journal":{"name":"2011 First International Conference on Data Compression, Communications and Processing","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123407640","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}
