Aggregate computing is an emerging macropro-gramming paradigm, whose validation is often performed by simulation. In this work, we compare the existing JVM-based toolkits from a performance point of view and show that they can be improved by adopting a different technique for implementing a core part of the semantics, called alignment, based on meta-programming implemented with a compiler plugin. © 2024 IEEE.

Efficiency with respect to energy consumption has increasingly been recognized as an important quality attribute for distributed software systems in embedded and pervasive environments. In this paper we present a framework for estimating the energy consumption of distributed software systems implemented in Java. Our primary objective in devising the framework is to enable an engineer to make informed decisions when adapting a system's architecture, such that the energy consumption on hardware devices with a finite battery life is reduced, and the lifetime of the system's key software services increases. Our framework explicitly takes a component-based perspective, which renders it well suited for a large class of today's distributed, embedded, and pervasive applications. The framework allows the engineer to estimate the distributed system's energy consumption at system construction-time and refine it at runtinie. In a large number of distributed application scenarios, the framework showed very good precision on the whole, giving results that were within 5% (and often less) of the actual energy consumption incurred by executing the software. Our work to date has also highlighted the framework's practical applications and a number of possible enhancements.

Automatic detection of P-wave in an electrocardiogram(ECG) is a crucial task in diagnosis of the presence of arrhythmias. In this paper, we proposed an improved method based on distance transform. Distance transform is an efficient method for locating P-wave critical points, corresponding to subjective judgment of cardiologists. Auxiliary algorithms have also been introduced to improve the precision of distance transform, such as recognition of horizontal segments and rising or declining segment, then, feedback comes to narrow or widen the P wave searching area for the need of distance transform. The method is validated through a QT database. The experiments show that our method provides good results. The average error of P-wave onsets, ends and P-wave location is 8.5ms,10.4ms, and 7.6ms, and P wave boundary point detection accuracy is 98.9%, 97.8% respectively. © 2016 IEEE.

The scheduling problem of Directed Acyclic Graph (DAG) with deadline constraints in a cloud computing environment has not been thoroughly studied. This paper concentrates on maximizing resource utilization and scheduling success rate in such scenarios. To achieve this, a scheduling algorithm based on dynamic downward rank and average input duration(DRAS) is proposed. This algorithm builds upon an enhanced version of the list scheduling approach. The DRAS algorithm is compared with four other scheduling algorithms to evaluate its performance. The comparative analysis demonstrates that the DRAS algorithm outperforms the other algorithms in terms of resource utilization and scheduling success rate. © 2023 IEEE.

Clustering based distributed phylogenetic tree construction

EXPERT SYSTEMS WITH applications 2012年第1期39卷 89-98页

作者： Ruzgar, Esra Erciyes, Kayhan Izmir Univ Comp Eng Dept TR-35350 Izmir Turkey

Phylogenetic tree construction has received much attention recently due to the availability of vast biological data. In this study, we provide a three step method to build phylogenetic trees. Firstly, a density-based clustering algorithm is used to provide clusters of the population at hand using the distance matrix which shows the distances of the species. Secondly, a phylogenetic tree for each cluster is constructed by using the neighbor-joining (NJ) algorithm and finally, the roots of the small phylogenetic trees are connected again by the NJ algorithm to form one large phylogenetic tree. To our knowledge, this is the first method for building phylogenetic trees that uses clustering prior to forming the tree. As such, it provides independent phylogenetic tree formation within each cluster as the second step, hence is suitable for parallel/distributed processing, enabling fast processing of very large biological data sets. The proposed method, clustered neighbor-joining (CNJ) is applied to 145 samples from the Y-DNA Haplogroup G. Distances between male samples are the variation in their set of Y-chromosomal short tandem repeat (STR) values. We show that the clustering method we use is superior to other clustering methods as applied to Y-DNA data and also independent, fast distributed construction of phylogenetic trees is possible with this method.

During the last few years, the concepts of cluster computing and heterogeneous networked systems have received increasing interest. The popularity of using Java for developing parallel and distributed applications that run on heterogeneous distributed systems has also grown rapidly. This paper is a survey of the current projects in parallel and distributed Java. These projects' main common objective is to utilize the available heterogeneous systems to provide high performance computing using Java. These projects were studied, compared and classified based on the approaches used. The study shows three major approaches. One is to develop a system that replaces the Java virtual machine (JVM) or utilizes the available parallel infrastructure such as MPI or PVM. Another is to provide seamless parallelization of multi-threaded applications. The third is to provide a pure Java implementation by adding classes and features that support parallel Java programming. In addition, a number of open issues are identified and discussed in this paper. © 2002 IEEE.

Cloud computing is gaining tremendous momentum in both academia and industry. The application of Cloud computing, however, has mostly focused on Web applications and business applications;while the recognition of using Cloud computing to support large-scale workflows, especially data-intensive scientific workflows on the Cloud is still largely overlooked. We coin the term "Cloud Workflow", to refer to the specification, execution, provenance tracking of large-scale scientific workflows, as well as the management of data and computing resources to enable the execution of scientific workflows on the Cloud. In this paper, we analyze why there has been such a gap between the two technologies, and what it means to bring Cloud and workflow together;we then present the key challenges in running Cloud workflow, and discuss the research opportunities in realizing workflows on the Cloud. © 2011 IEEE.
