RCE 35: PVFS Parallel Virtual FileSystem

MP3 (Right Click Save As)

UPDATE: The first version of this show had some encoding issues. The current copy does not.

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.

Brock Palen and Jeff Squyres speak with Samuel Thibault of the University of Bordeaux and INRIA, about hwloc.

Samuel Thibault is an Assistant Professor in the University of Bordeaux (France), working in the Runtime INRIA team. He received his PhD in distribution of HPC application threads over hierarchical machines in 2007, the hierarchy part of which was turned and improved into the hwloc library and tools in 2009. His current research interests now also include scheduling tasks on both CPUs and GPUs, and the use of virtualization for HPC. In a second life, he is also a Debian Developer focused on accessibility support (particularly for blind users), and a GNU/Hurd developer.

Brock Palen and Jeff Squyres speak with Michael DeHaan of Puppet Labs about Puppet, a tool for data center automation.

Michael DeHaan is the product manager for Puppet Labs (http://puppetlabs.com), the makers of Puppet, an open source data center automation and configuration management framework. Puppet provides system administrators with a simplified platform that allows for consistent, transparent, and flexible systems management. Before joining Puppet Labs, Michael created and ran the Cobbler (http://fedorahosted.org/cobbler) project at Red Hat and also helped create Func (http://fedorahosted.org/func).

RCE 31: lammps Clasical Molecular Dynamics

MP3 (Right Click Save As)

Brock Palen and Jeff Squyres speak with Steve Plimpton about the classical MD code Lammps.

Steve Plimpton is a staff member at Sandia National Laboratories, a US DOE laboratory, where he's been a member of the Computation, Computers, Information, and Mathematics center for the past 20 years, currently in the Scalable Algorithms group. His work involves implementing and using scientific simulations designed for parallel supercomputers. Often this includes the creation of efficient parallel algorithms; see http://www.sandia.gov/~sjplimp. He has written and distributes a variety of open-source software, including molecular dynamics, kinetic Monte Carlo, and biological cell simulators, as well as a MapReduce library written on top of MPI.

Brock Palen and Jeff Squyres speak with Jason Stowe of Cycle Computing and Greg Thain of UofW Madison about Condor.

Jason Stowe is the founder and CEO of Cycle Computing(http://www.cyclecomputing.com), a leading provider of open-source, High Performance Computing (HPC) technology on internal desktops, servers, and in the Cloud. Leveraging its expertise with internal HPC, Cycle helps clients provision large-scale, secure HPC clusters in the cloud on demand. Cycle supports open-source Condor & Hadoop, as well as PBS/SGE, to provide innovative administrative functionality and reduce costs in managing small clusters to environments of 30,000+ CPUs. Jason attended Carnegie Mellon and Cornell Universities, guest lectured at Cornell's Johnson Business School, and sits on Amazon's Customer Advisory Board.

Greg Thain is a systems programmer working as a staff member of the Condor Project at the University of Wisconsin - Madison. As part of the core condor flighworthy team, he was worked on many aspects of Condor, including the Condor Parallel Universe, the master-worker framework for parallel computing, and tuning the performance of the system as a whole. Greg has a BS in Computer Sciences from the University of Wisconsin.
