RCE 39: xCAT Extreme Cloud Administration Toolkit

Brock Palen and Jeff Squyres speak with Egan Ford of IBM and Vallard Benincosa of Sumavi. They took time out to talk about xCAT, The Extreme Cloud Administration Toolkit

MP3 (Right Click Save As)

Vallard Benincosa is a founding engineer of Sumavi Inc, a company dedicated to scaled-out management of data centers. Part of the mission of Sumavi is to provide commercial support for xCAT and to extend its capabilities for the enterprise by focusing on ease of-use. Previous to starting Sumavi, Vallard worked at IBM designing, implementing, and supporting large scale cluster solutions including LANL Roadrunner, Toronto' SciNet, NASA, Honda, ARL, Lucas Film, Two University of California clusters, etc. During these implementations Vallard would write code that would eventually be incorporated into xCAT. Vallard holds an MBA from New York University and a BA in Computer Science from UC Berkeley.

Egan Ford started building Web and HPC Linux clusters in 1999 and was the chief architect for IBM's first large HPC cluster (Los Lobos at the University of New Mexico). Since then Egan has led in the design and implementation of some of IBM's largest systems including AIST, LANL Roadrunner, and the US National Science Foundation Teragrid (teragrid.org). Egan is the creator of IBM's first cluster management solution (xCAT) and co-author of two IBM RedBooks on Linux HPC.

Brock Palen and Jeff Squyres speak with Kay Hunt and Scott Lathrop of TeraGrid.

Kay Hunt is the Project Coordinator for the TeraGrid Campus Champions Program, a national project sponsored by the National Science Foundation. The Campus Champions program supports campus representatives as the local source of knowledge about high-performance computing opportunities and resources. She has responsibility for over 85 Campus Champions located at over 60 institutions who develop relationships between and among faculty and staff. The knowledge and assistance provided by the Champions empower campus researchers, educators, and students to advance scientific discovery. Kay's responsibilities with the TeraGrid, in addition to the Campus Champion program, are working with the Education, Outreach, and Training group and the External Relations group. Kay's primary focus at Purdue University is project management, communications, and outreach. Kay has been with Purdue University over 35 years and has many years experience in information technology and research. She received her Bachelor of Arts degree in Mathematics from Indiana University.

Scott Lathrop splits his time between being the TeraGrid Director of Education, Outreach and Training (EOT) at the University of Chicago/Argonne National Laboratory, and being the Blue Waters Technical Program Manager for Education for NCSA. Lathrop has been involved in high performance computing and communications activities since 1986. Lathrop coordinates education, outreach and training activities among the eleven Resource Providers involved in the TeraGrid project. He coordinates undergraduate and graduate education activities for the Blue Waters project. Lathrop is Co-PI on the NSF funded Computational Science Education Reference Desk (CSERD), a Pathways project of the National Science Digital Library (NSDL) program. Lathrop is the SC11 Conference Chair. Lathrop is project manager for a Department of Education Atlantis project in collaboration with the Cyprus Institute.

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.

MP3 (Right Click Save As)

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.
