Stephen L. Scott (scottsl@ornl.gov) is a senior research scientist in the Computer Science and Mathematics Division of Oak Ridge National Laboratory – USA. Dr. Scott’s research interest is in experimental systems with a focus on high performance distributed, heterogeneous, and parallel computing. He is a founding member of the Open Cluster Group (OCG) and Open Source Cluster Application Resources (OSCAR) – and has served in the capacity of both release manager and working group chair. Stephen has published numerous papers on cluster and distributed computing and has both a Ph.D. and M.S. in computer science; is a member of ACM, IEEE Computer, and the IEEE Task Force on Cluster Computing.

Dr. Daniel Okunbor is a professor in the Department of Mathematics and Computer Science at Fayetteville State University. He is currently a visiting research scientist in the Computer Science and Mathematics Division of the Computing and Computational Sciences Directorate at Oak Ridge National Laboratory with support from the ORISE/ORAU HBCU/MI Faculty Summer Research Participation Programs. His research includes scientific and distributed computing with emphases on reliability, availability and serviceablity (RAS) in terascale computing; and molecular dynamics simulations of biomolecules.

John Mugler is a research associate working on the SciDAC: Scalable System Software (SSS) and Open Source Cluster Application Resources (OSCAR) projects. Prior to starting at Oak Ridge National Laboratory John was a graduate student at Middle Tennessee State University where he received his M.S. degree in Computer Science in December of 2001. Previously, John worked for an engineering company that specialized in life sciences. His research interests include: high-performance cluster computing, parallel genetic algorithms and networking. John is currently the Release Manager for the OSCAR project.

Thomas Naughton is a research associate working on the SciDAC, Scalablem System Software (SSS), and Open Source Cluster Application Resources (OSCAR) projects. Prior to starting at Oak Ridge National Laboratory, Thomas was a graduate student at Middle Tennessee State University where he received his M.S. degree in Computer Science in December of 2000. Thomas also completed a B.S. in Computer Science and a B.A. in Philosophy at the University of Tennessee at Martin in 1998. His research interests include: high-performance cluster computing, build and configuration systems and networking. Thomas is a member of ACM and was the 2003 OSCAR Working Group Chair.

Since March 2004, Dr. Geoffroy has been an industrial PostDoctorant at INRIA, co-funded by Electricite De France R&D (EDF R&D). Dr. Geffroy carry on methods for building, programming, and using clusters, developing a fully integrated and easy to install software bundle designed for high performance cluster computing. A solution to oer ease programming and ease use of clusters is to used a Single System Image (SSI) as cluster system. Dr. Valle also worked on the creation of a SSI package for the OSCAR, a cluster distrubution which provides a snapshot of the best known methods for building, programming, and using clusters. For that, I have integrated the OSCAR team at the Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA, during one year in the framework of my PostDoctorant position.

Wesley is a Junior studying Computer Science at Tennessee Technological University. He is participating in the Student Undergraduate Laboratory Internship program through the US Department of Energy for the second year. Wesley's research is working on C3 by fixing bugs and adding functionality which also deals with HA-OSCAR.
