Nowadays, more and more program analysis tools adopt pro- filing approaches in order to obtain data dependences because of their ability of tracking dynamically allocated memory, pointers, and array indices. However, ...

Feature extraction is one of the essential parts of multimedia indexing in similarity search and content-based retrieval methods. Most applications that employ these methods also implement their client side interface using web technologies. the world wide web has become a well-established platform for distributed software and virtually all personal computers, tablets, and smartphones are equipped with a web browser. In the past, most applications employed a strict client-server approach, where the client part (running in the browser) handles only the user interface and the server side handles data storage and business logic. However, the client-side technologies leaped forward withthe new HTML5 standard and the web browser has become capable of handling much more complex tasks. In this paper, we propose a model where the multimedia indexing is handled at the client side, which reduces necessary computational power of the server to run a web application that manages large multimedia database. We have implemented an in-browser image feature extractor and compared its performance with a server implementation.
While researchers have concentrated on the optimization of joint redundancy and maintenance mechanism, maintenance in computing systems is quite different from that in traditional systems. Considering a routine monito...

Scheduling algorithms published in the scientific literature are often difficult to evaluate or compare due to differences between the experimental evaluations in any two papers on the topic. Very few researchers share the details about the scheduling problem instances they use in their evaluation section, the code that allows them to transform the numbers they collect into the results and graphs they show, nor the raw data produced in their experiments. Also, many scheduling algorithms published are not tested against a real processor architecture to evaluate their efficiency in a realistic setting. In this paper, we describe Mimer, a modular evaluation tool-chain for static schedulers that enables the sharing of evaluation and analysis tools employed to elaborate scheduling papers. We propose Schedeval that integrates into Mimer to evaluate static schedules of streaming applications under throughput constraints on actual target execution platforms. We evaluate the performance of Schedeval at running streaming applications on the Intel Single-Chip Cloud computer (SCC), and we demonstrate the usefulness of our tool-chain to compare existing scheduling algorithms. We conclude that Mimer and Schedeval are useful tools to study static scheduling and to observe the behavior of streaming applications when running on many core architectures.
Distributed storage systems can provide large-scale data storage and high data reliability by redundant schemes, such as replica and erasure codes. Redundant data may get lost due to frequent node failures in the syst...

this paper presents parallel strategies applied to Harmony Search (HS) on CUDA for solving Traveling Salesman Problem (TSP), which is an NP-hard problem in combinatorial optimization. the implementations are tested with data instances of varying problem size from TSPLIB to measure speedup attained over serial implementation. In our experiment, HSGPU parallel implementation can acquire 32 times speedup as compared with CPU-based implementation.
the rapidly increased data size make large scale scientific database often have a huge time delay between loading data into the system and ready for receiving query request. To solve this problem, we proposed an effic...
