Dr. Stephen L. Scott is a research scientist in the Network and Cluster Computing Group of the Computer Science and Mathematics Division of Oak Ridge National Laboratory (ORNL) - USA. He has received the Ph.D. and M.S. in computer science from Kent State University, Kent, Ohio - USA. He also received a B.A. from Thiel College, Greenville, PA - USA. At Oak Ridge National Laboratory, Stephen's responsibilities include research and development efforts in high performance scalable cluster computing as well as directing research staff in this effort. Primary research interest is in experimental systems with a focus on high performance, scalable, distributed, heterogeneous, and parallel computing. He is also a contributor to the Parallel Virtual Machine (PVM) and Heterogeneous Adaptable Reconfigurable NEtworked SystemS (HARNESS) research efforts at ORNL (http://www.csm.ornl.gov/pvm and http://www.csm.ornl.gov/harness). Stephen is a founding member as well as a steering committee member of The Open Cluster Group (OCG) (http://www.OpenClusterGroup.org). This organization is a consortium of research and industry that is dedicated to making cluster computing practical for high performance computing. Stephen is also a founding member and past working group chair of the OCG's primary working group, Open Source Cluster Application Resources (OSCAR) (http://oscar.sourceforge.net). This working group is dedicated to bringing current "best practices" in cluster computing to all users via a self-installing cluster-on-a-CD suite. He is also a member of ACM, IEEE Computer, and the IEEE Task Force on Cluster Computing. Prior to attending graduate school, Stephen worked various industry positions including one as principal with a business-to-business chemical database startup company.
