RCE 20: Silo

MP3 (Right Click Save As)

Brock Palen and Jeff Squyres speak with Mark Miller on the Silo (wci.llnl.gov/codes/silo) storage format.  Mark also works on the Visit (wci.llnl.gov/codes/visit) project which were our guests on RCE 6.

Be sure to catch Jeff and Brock at SC09 this year in Portland!

Mark received his Ph.D. from U.C. Davis in EE with emphasis on compression of very large datasets for real-time signal processing. I started at LLNL in May of 1995 working on I/O analysis of Silo. From there, I became involved in the ASCI Data Models and Formats effort leading the development of the Sets and Fields (SAF, pronounced 'safe') data modeling system where I also became involved in scalable, parallel I/O. Then, I moved to VisIt, adding scalable rendering as my first major enhancement. Since then, I have been working about 50-75% time on VisIt, 25% time on Silo and, more recently, on ITAPS SciDAC project.

More Shows Comming Soon - Nominate


There will be no show this period.  Both Jeff and I have been very busy.  We will be back with another show soon on Silo (https://wci.llnl.gov/codes/silo/).  Also checkout the old shows, iTunes only shows the last few shows, but all of our old shows are still available, so those of you who are new listeners catchup on what we have been up to.

 Also please nominate any topics you would like to hear about. We do not limit to software projects, hardware or topic discussions/round tables are open also, so please let us know!

RCE 16: Rocks Clusters

MP3 (Right Click Save As)

Brock Palen and Jeff Squyres speak with Mason Katz and Greg Bruno of UCSD (University of California San Diego)  about the Rocks Cluster (http://www.rocksclusters.org/) distribution.

Greg Bruno is a core architect and developer of the Rocks Cluster Distribution and he has been involved with the project since its inception. Over the past 10 years, Rocks has helped "make clusters easy" for scientists from around the world as proven by the Rocks Cluster Registration Page (www.rocksclusters.org/register) where, as of August 2009, over 1,200 clusters have been voluntarily registered. Additionally, Rocks has been recognized by the HPC community by winning six HPCwire awards. He has co-authored four refereed technical conference papers on the topic of Rocks. Dr. Bruno received his Ph.D. from the University of California at San Diego in Computer Science in 2008. Prior to co-founding the Rocks Development Group, he worked at NCR where he developed cluster management software for systems that support the world's largest databases. During his 10 year employment at NCR, he co-authored three awarded patents (Patent Numbers:6,119,159 - 6,308,207 - 6,081,812).

Mason J. Katz is currently the Group Leader for Cluster Development for the San Diego Supercomputer Center (SDSC) at the University of California (UCSD). Mr. Katz received his BS in Systems Engineering from the University of Arizona. He worked for five years as an embedded software engineer on networks of lightning detection sensors. Following this his spent three years working at the University of Arizona on network security protocols (IPSec), and operating systems (x-kernel, Scout). Recently he has spent the last six years working on Windows and Linux commodity clustering (HPVM, Rocks). The focus of his current work is on the Rocks Clustering Distribution, a complete software stack building high performance computing clusters. Rocks has an international user community of several thousand users, and has an international development team of a dozen software developers. In addition, Mr. Katz is actively involved in Pacific Rim Applications and Grid Middleware Assembly (PRAGMA) having served as co-chair for two meetings, and as co-lead for the Resources Working Group.

Brock Palen and Jeff Squyres speak with Narayan Desai and Cory Lueninghoener of Argonne National Laboratory, about BCFG2 (http://trac.mcs.anl.gov/projects/bcfg2).

Narayan Desai is a principal experimental systems engineer at Argonne National Laboratory. He specializes in system software and system management issues, specifically for very large scale parallel computing systems. He has written and spoken widely on these issues, and leads the Bcfg2 configuration management project.

Cory Lueninghoener is a high performance computing system administrator at Argonne National Laboratory.  After starting out on modest-sized clusters while a grad student at the University of Nebraska, he worked his way up the Top500 list and is currently a lead administrator on Intrepid, Argonne's 40 rack BlueGene/P system.  He is especially interested in configuration management on large HPC resources and is an active participant in the Bcfg2 project.
