Modern Information Retrieval Systems match the terms of a user query with available documents in their index and return a large number of Web pages generally in the form of a ranked list. It becomes almost impractical at the user end to examine every returned document, thus necessitating the need to look for some means of result optimization. In this paper, a novel result optimization technique based...
To overpass the speed gap between processor and main memory; cache memory is used. Cache memory is having hierarchical structure, including level 1 cache (L1), level 2 cache (L2) etc. Effective page replacement algorithm will result in effectual utilization of cache. L1 is having rich temporal locality while L2 is having poor temporal locality, thus same replacement algorithms for both the levels...
Access to the Internet and WWW is growing extensively, which results in heavy network traffic. To reduce the network traffic proxy server is used. Proxy server reduces the load of server. If the cache replacement algorithm of proxy server's cache is efficient then proxy server will be helpful to reduce the network traffic in more efficient manner. In this paper we are considering proxy server cache...
The increasing complexity and dynamics in IT infrastructure and the emerging Cloud services present challenges to timely incident/problem diagnosis and resolution. In this paper we present a problem determination platform with multi-dimensional knowledge integration (e.g. configuration data, system vital data, log data, related tickets) and enablement for efficient incident and problem management...
We present a tool called BugFix that can assist developers in fixing program bugs. Our tool automatically analyzes the debugging situation at a statement and reports a prioritized list of relevant bug-fix suggestions that are likely to guide the developer to an appropriate fix at that statement. BugFix incorporates ideas from machine learning to automatically learn from new debugging situations and...
Prior work has shown that computing dynamic slices of erroneous program values can greatly assist in locating the root cause of erroneous behavior by identifying faulty statements in sequential programs. These dynamic slices represent backward transitive closure over exercised read-after-write data dependences and control dependences. However, for a multithreaded program executing on a processor,...
