RCE 10: SLURM

MP3 (Right Click Save As)

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
(CTSS) operating system. He has spent most of the past 20 years working on computing scheduling issues for the HPC environment including the development of several gang schedulers.

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.

He has been running systems of various types since 87, iPSC/2, Alliant, IBM SP/2, various Linux clusters.
 

Josh Butikofer is the Director of Grid Technologies at Cluster Resources, Inc. He is primarily involved with overseeing and participating in development of the TORQUE Resource Manager and Moab family of products. Josh has been active in the HPC software industry for several years and has been involved in improving the scalability and performance of distributed software since 1999. He graduated summa cum laude from Brigham Young University.
 

RCE 07: Cluster Planning

MP3 (Right Click Save As)

 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).

Brock Palen and Jeff Squyres speak with Brice Goglin of the Open-MX (http://www.open-mx.org) project, a software implementation of Myrinet Express, providing low latency over stock ethernet networks.

 

Brice Goglin is the primary developer of the Open-MX project. He works at the LaBRI laboratory in Bordeaux (France) as an INRIA researcher (the French institute for research in computer science and control). He has
been working on HPC software design for several years, especially on implementing software support for high-speed networks such as Myricom Myrinet and Myri-10G technologies. He earned his PhD at the Ecole
normale superieure de Lyon (France) in 2005. His research topics nowadays include high-speed networking in the context of the convergence between HPC and traditional Ethernet networks, as well as the design of high-performance runtime systems for upcoming NUMA architectures.

about Google's core data management and processing technologies - MapReduce and GFS. This quickly brought Hadoop into the curriculum, and has since resulted in an extensive partnership with the National
Science Foundation (NSF) which makes Google-hosted Hadoop clusters available for research and education worldwide. Beyond his work with Hadoop, he holds patents related to search quality and personalization, and spent a year working in Shanghai. Christophe earned his degree, and remains a visiting scientist, at the University of Washington.
