The convergence behavior of many distributed machine learning (ML) algorithms can be sensitive to the number of machines being used or to changes in the computing environment. As a result, scaling to a large number of machines can be challenging. In

Computer systems increasingly rely on heterogeneity to achieve greater performance, scalability and energy efficiency. Because heterogeneous systems typically comprise multiple execution contexts with different programming abstractions and runtimes,

Query rewriting algorithms can be used as a form of query expansion, by combining the user's original query with automatically generated rewrites. Rewriting algorithms bring linguistic datasets to bear without the need for iterative relevance feedbac

In this paper, we investigate near-duplicate detection, particularly looking at the detection of evolving news stories. These stories often consist primarily of syndicated information, with local replacement of headlines, captions, and the addition o

Many phenomena and artifacts such as road networks, social networks and the web can be modeled as large graphs and analyzed using graph algorithms. However, given the size of the underlying graphs, efficient implementation of basic operations such as

The main motivation behind the development of DryadLINQ was to make it easier for non-specialists to write general purpose, scalable programs that can operate on very large input datasets. In order to appeal to non-specialists we designed the program

We present a study of the contributions of three classes of ranking signals: BM25F, a retrieval function that is based on words in the content of web pages and the anchors that link to them; SALSA, a link-based feature that takes all or part of the r

Due to the explosive growth of the web that has occurred throughout its history, many researchers working on web corpora have begun to move toward distributed, data parallel computing. The size of the ClueWeb09 [2] corpus, at approximately one billio

Crawl selection policy has a direct influence on Web search effectiveness, because a useful page that is not selected for crawling will also be absent from search results. Yet there has been little or no work on measuring this effect. We introduce an

Previous scalability experiments found that early precision improves as collection size increases. However, that was under the assumption that a collection's documents are all sampled with uniform probability from the same population. We contrast thi
