Solid-state disks (SSDs) are becoming widely used in personal computers and are expected to replace a great portion of magnetic disks in servers and supercomputers. Although many high-speed SSDs are present in the market, both the design of hardware architecture and the details of the flash translation layer (FTL) are not well known. Meanwhile, in the(More)
Web search engine ranks web pages according to their relevance to user queries, which is critical for the success of commercial search engines. Rank Boost algorithm is promising in Web relevance ranking area, while its computation complexity makes our existing implementations (including single node software-based implementation and a FPGA-based accelerator)(More)
Search relevance is a key measurement to judge the usefulness of search engines, which may change a search company’s market cap by tens of billions of dollars. With the ever-increasing scale of the World Wide Web, machine learning technologies have become important tools to improve search relevance rankings. However, these machine learning algorithms are(More)
