Brock Palen and Jeff Squyres speak with Walter Ligon about PVFS2 the parallel file system.

Walt Ligon completed his PhD in Computer Science at the Georgia Institute of Technology in 1992. Since then he has been a member of the faculty in the Holcombe Department of Electrical and Computer Engineering at Clemson University, where he teaches computer engineering and performs research on high performance computing. Walt’s group developed the Parallel Virtual File System (PVFS) – an open source parallel file system for Linux as part of the Beowulf project at Goddard Space Flight Center in the mid 1990’s. PVFS has since become a project jointly developed at several national labs and universities world wide. Currently Walt’s group is working on techniques for improving small file accesses, metadata accesses, security, and reliability for parallel file systems. Other research activities Walt has been part of have included parallel programming environments and reconfigurable computing architectures. Walt continues to be active in conducting funded research, publishing, and teaching.
