Brock Palen and Jeff Squyres speak with Paul Hargrove of the Berkley Labratory Checkpoint Restart (BLCR) project, for checkpointing, restartaring and migrating HPC applications. Notes: All library code is LGPL; kernel module and the (small) user-space utils are GPL. There is also support for BLCR in SLURM 2.0 which is not mentioned in the show. Since 2000, Paul has been a Principle Investigator in the Future Technologies Group (FTG) at Lawrence Berkeley National Laboratory (LBNL). His general area of work can be described as systems software and runtime environments for High Performance Computing (HPC). His current research interests include Checkpoint/Restart, Partitioned Global Address Space (PGAS) languages, and high-performance cluster networks. Current projects include Berkeley Lab Checkpoint/Restart (BLCR) for Linux, Global Address Space Networking (GASNet), and Berkeley Unified Parallel C (UPC). Paul received his Ph.D. from Stanford University in 2003. RCE 11: UM Atlas

Brock Palen and Jeff Squyres speak with Shawn McKee from The University of Michigan about the Atlas (altas.ch) detector, part of the Large Hadron Collider (lhc.web.cern.ch/lhc/) at Cern. Panda Information: https://twiki.cern.ch/twiki/bin/view/Atlas/Panda Shawn McKee (Ph.D., UM 1991) is a high-energy astrophysicist and research scientist at the University of Michigan. He is currently a member of the ATLAS experiment at the Large Hadron Collider at CERN. His work has been central to advancing computing technology to address the simulation and data analysis requirements of ATLAS. ATLAS, with its multi-Petabyte per year data flow, represents a significant challenge for even the existing computing infrastructure of 2009. Since 2006, Shawn has been the Director of the ATLAS Great Lakes Tier-2 (AGLT2) computing center, located at the University of Michigan and Michigan State University, one of five such centers in the US providing computing resources to support ATLAS simulation and data analysis. In 2001, he was appointed Network Project Manager for US ATLAS to plan for and develop the necessary network environment to support the US ATLAS computing model. He is co-chair of the High-Energy and Nuclear Physics (HENP) Internet2 Working Group, which is addressing similar problems in the context of all of high-energy and nuclear physics experiments.

Brock Palen and Jeff Squyres speak with Moe Jette and Danny Auble of LLNL about the SLURM Resource Manager. Danny Auble joined the SLURM team in 2004 to develop the port to the IBM bluegene infrastructure. Since then he has been the primary on many parts of SLURM including the tree fanout used for communication with the slurmd's, the accounting system, and the multifactor priority plugin. He began working at Lawrence Livermore National Laboratory in 2001, soon after graduating from Brigham Young University. Morris Jette has been the SLURM project leader since its inception in 2001. He began systems programming at Lawrence Livermore National Laboratory in 1980, helping to develop the Cray Time-Sharing System RCE 09: HDF5

Brock Palen and Jeff Squyres speak wtih Mike Folk and Quincey Koziol of The HDF Group about the HDF5 file API. Mike Folk is President and Executive Director of The HDF Group. Mike led the NCSA HDF project from 1988 until 2006, when The HDF Group became an independent, non-profit company dedicated to meeting the needs of HDF users and assuring access to their data for the long haul. Mike’s first programming job was in 1961, as a student at the University of North Carolina. Later Mike taught high school math in the U.S. and Africa, got a PhD in CS from Syracuse University, then taught computer science at the university level for 18 years. Mike’s modest list of publications include the book File Structures, a Conceptual Toolkit, by Folk and Zoellick (1987, 1991). Quincey Koziol has been with The HDF Group (THG) since its founding and started with the HDF group in 1991, when it was still part of the National Center for Supercomputing Applications. He serves as the Director of Software Development for THG, overseeing the design and architecture of the HDF5 software, as well as providing software engineering leadership for THG. Quincey received his Bachelor's degree in Electrical Engineering from the University of Illinois and is pursuing his Master's degree in Computer Science from the U of I also.

Brock Palen and Jeff Squyres have a short discussion with Douglas Eadline and Jeff Layton about planning of the construction of HPC clusters. Douglas Eadline, Ph.D. has worked with parallel computers since 1988 (anyone remember the Inmos Transputer?). He has a large amount of experience (and opinions) with parallel software tools and and application performance. Doug has been building and using Linux clusters since 1995. One of his current interests is in Personal Clusters. Presently, he is Editor of ClusterMonkey.net, Senior HPC Editor at Linux Magazine, and an instructor/consultant. Jeff Layton is a long-time cluster monkey and all round cluster enthusiast having been a customer, admin, developer, writer, and now works for a cluster vendor. He works at Dell as the HPC Enterprise Technologist. Previously he worked for Panasas, Linux Networx, Lockheed Martin, Boeing, NASA, and was a professor of Aeronautical Engineering for a time (this makes him seem much older that he really is). Jeff writes for Cluster Monkey (www.clustermonkey.net), Linux Magazine (www.linux-mag.com), Dell Tech Center (www.delltechcenter.com/page/hpcc), and his own feeble attempt at a blog - ClusterBuffer (clusterbuffer.wetpaint.com).
