“…GLARE [6]) propose approaches to install and deploy scientific applications with less involvement of administrators. Projects like CGSP2 [2] support traditional legacy software tools to be packaged and wrapped as Web Services so that they can be manually transferred to and invoked on other nodes without reinstallation. Though all these studies more or less address dynamic deployment of applications from different perspectives, none of them have taken the improvement of overall system performance into account.…”

SUMMARYGrid applications are normally deployed on computing nodes beforehand, which may cause the undesirable situation that some of these nodes (with hot applications deployed) are always busy whereas the others are consistently idle. Therefore, the overall performance (e.g. throughput and load balancing) of such a Grid system would be seriously degraded. In this paper, we present the idea of Hierarchical and Dynamic Deployment of Application (HDDA) in Grid to improve the system performance. With HDDA, an application can be dynamically deployed and undeployed when necessary. In order to reduce the overhead caused by HDDA, the Average Latency Ratio Minimum (ALR-MIN) replacement strategy is also proposed. It deploys applications to nodes with minimum ALR of Node (NALR), and evicts applications with minimum increment of ALR. The results of the experiment we conducted on ChinaGrid show that HDDA can achieve 10 and 24% less average complete time (ACT) than the schemes of non-HDDA and Static Deployment of Application (SDA), respectively. Additionally, throughput and load balancing of HDDA are also better than the other two schemas. Results of the simulation performed on a simulator particularly developed for this research show that our ALR-MIN replacement strategy results in 17% less relative delay-time of jobs than the well-known Least Recently Used (LRU)-based strategies in a typical setting.

“…As a result, BPEL-based specifications might be one of the prospective ways to fill the gap of scarcity in chemical research on scientific workflow of requirement and workflow standards. It also requires GRS [16] on CGSP [17]- [19], [36] to complete the experiments which content usage of legacy programs. We also develop a visual scientific workflow designer, which is a graphical representation of the BPEL specification simple for chemoinformatics studies.…”

Chemical research is an exploring and improving process to obtain the preferable experiment result. The complex and frequently changing research in traditional way is time-consuming, expending energy and repetitive work. The emergence of scientific workflow congregating orchestrating distributed resources and scientific instruments on the Grid environment possibly solves these problems in chemical research by automating experiment process. BPEL as the de-facto workflow language standard provides the standardized environment to perform chemical research on scientific workflow by utilizing distributed resources on Grid in parallel. This paper discusses requirements of chemical research of scientific workflow on Grid and analyses the features of BPEL. The features conduce to the workflow fulfilling the optimizing chemical experiment effectively by satisfying the scalability and reliability requirements of chemical research on scientific workflows. Finally, the case study demonstrates feasibility of BPEL applied on chemical research, which proves that BPEL is exactly suitable for chemical research on Grid.

In the recent years, many efforts have been made for the development of the Grid workflow systems. Currently most Grid workflow systems focus on data analysis function or specific Grid applications, while building large-scale scientific collaborative applications is still not easy for common users. In this paper, requirement of Grid workflow spanning multiple grids was introduced firstly. Then, a highly scalable, more usable Grid workflow framework is proposed. The framework provides abstract components that facilitate Grid-based workflow construction, and can integrate multiple Grids' resources into a single system with an intuitive graphical user interface. Furthermore, a prototype system based on this framework was developed, along with a simple bioinformatics application workflow as a demonstration.
