With more and more workflow systems adopting cloud as their execution environment, it becomes increasingly challenging on how to efficiently manage various workflows, v irtual machines (VMs) and workflow execution on VM instances. To make the system scalable and easy-to-extend, we design a Workflow as a Service (WFaaS) architecture with independent(More)
One of the greatest challenges in computational chemistry is the design of enzymes to catalyze non-natural chemical reactions. We focus on harnessing the distributed parallel computational power of the Grid to automate the inside-out process of enzyme design using scientific workflow systems. This paper presents a scientific workflow based approach to(More)
e-Science has been greatly enhanced from the developing capability and usability of cyberinfrastructure. This chapter explains how scientific workflow systems can facilitate e-Science discovery in Grid environments by providing features including scientific process automation, resource consolidation, parallelism, provenance tracking, fault tolerance, and(More)
21st Century Smart Manufacturing (SM) is manufacturing in which all information is available when it is needed, where it is needed, and in the form it is most useful [1,2] to drive optimal actions and responses. The 21st Century SM enterprise is data driven, knowledge enabled, and model rich with visibility across the enterprise (internal and external) such(More)
The University of California (UC) has adopted the UCLA Grid Portal (UGP), a Globus Incubator project, to create grids of computational clusters [1] at its campuses. Campus grids can also be accessed system wide via the UC Grid Portal. Developed as a set of portlets for the GridSphere Portal Framework, parts of UGP, such as those for data management and job(More)
Historic manufacturing enterprises based on vertically optimized companies, practices, market share, and competitiveness are giving way to enterprises that are responsive across an entire value chain to demand dynamic markets and customized product value adds; increased expectations for environmental sustainability, reduced energy usage, and zero incidents;(More)
In this paper we describe our experience in investigating private cloud storage solutions and architectures for long-term data archival storage purpose. The storage solution needs in a campus research environment requires reliability and scal-ability up to petabytes of data at the minimum. The key requirements for a reliable and scalable cloud storage(More)
