Ron A. Oldfield is a Ph.D. candidate in Computer Science at Dartmouth College. He received the BS in computer science from the University of New Mexico in 1993. From 1993 to 1997, he worked in the computational sciences department of Sandia National Laboratories, where he specialized in seismic research and parallel I/O. He was the primary developer for the GONII-SSD (Gas and Oil National Information Infrastructure-Synthetic Seismic Dataset) project. For GONII, he implemented a parallel 3D finite-difference acoustic wave propagation code that was used to generate a large synthetic seismic dataset. He also worked on the R&D 100 award-winning project "Salvo", a project to develop a 3D finite-difference prestack-depth migration algorithm for massively parallel architectures. His work with the Salvo focused on minimizing the effect of the massive I/O requirements associated with seismic processing. At Dartmouth, his research targets parallel file systems and parallel I/O for the wide-area distributed systems. He is also an active member of Global Grid Forum.
