BSDCan-2011 - Brooks Davis - Improving System Management with ZFS
The Zetabyte File System (ZFS) is a modern file system which combines traditional file system features like a POSIX file system interface with RAID and volume management functionality. Features such as snapshot management and file share management are all managed within the ZFS interface. This management interface provides a number of opportunities to simplify system management. In the Technical Computing Services Sub-division of The Aerospace Corporation we are taking advantage of these features in a number of different ways. This talk presents some of the more interesting ones.

EuroBSDCon 2008 - Brooks Davis - Isolating cluster jobs for performance and predictability
The Aerospace Corporation operates a federally funded research and development center in support of national-security, civil and commercial space programs. Many of our 2400+ engineers use a variety of computing technologies to support their work. Applications range from small models which are easily handled by desktops to parameter studies involving thousands of cpu hours and traditional, large scale parallel codes such as computational fluid dynamics and molecular modeling applications. Our primary resources used to support these large applications are computing clusters. Our current primary cluster, the Fellowship cluster consists of 352 dual-processor nodes with a total of 14xx cores. Two additional clusters, beginning at 150 dual-processor nodes each are being constructed to augment Fellowship. As in In any multiuser computing environment with limited resources, user competition for resources is a significant burden. Users want everything they need to do their job, right now. Unfortunately, other users may need those resources at the same time. Thus, systems to arbitrate this resource contention are necessary. On Fellowship we have deployed the Sun Grid Engine scheduler which scheduled batch jobs across the nodes. In the next section we discuss the performance problems that can occur when sharing resources in a high performance computing cluster. We then discuss range of possibilities to address these problems. We then explain the solutions we are investigating and describe our experiments with them. We then conclude with a discussion of future work.

Building a High-Performance Computing Cluster Using FreeBSD
Special NYC*BUG meeting with FreeBSD developer Brooks Davis Since late 2000 we have developed and maintained a general purpose technical and scientific computing cluster running the FreeBSD operating system. In that time we have grown from a cluster of 8 dual Intel Pentium III systems to our current mix of 64 dual, quad-core Intel Xeon and 289 dual AMD Opteron systems. In this talk we reflect on the system architecture as documented in our BSDCon 2003 paper "Building a High-performance Computing Cluster Using FreeBSD" and our changes since that time. After a brief overview of the current cluster we revisit the architectural decisions in that paper and reflect on their long term success. We then discuss lessons learned in the process. Finally, we conclude with thoughts on future cluster expansion and designs. Bio Brooks Davis is an Engineering Specialist in the High Performance Computing Section of the Computer Systems Research Department at The Aerospace Corporation. He has been a FreeBSD user since 1994, a FreeBSD committer since 2001, and a core team member since 2006. He earned a Bachelors Degree in Computer Science from Harvey Mudd College in 1998. His computing interests include high performance computing, networking, security, mobility, and, of course, finding ways to use FreeBSD in all these areas. When not computing, he enjoys reading, cooking, brewing and pounding on red-hot iron in his garage blacksmith shop.

Brooks Davis - Isolating Cluster Jobs for Performance and Predictability
Isolating Cluster Jobs for Performance and Predictability At The Aerospace Corporation, we run a large FreeBSD based computing cluster to support engineering applications. These applications come in all shapes, sizes, and qualities of implementation. To support them and our diverse userbase we have been searching for ways to isolate jobs from one another in ways that are more effective than Unix time sharing and more fine grained than allocating whole nodes to jobs. In this talk we discuss the problem space and our efforts so far. These efforts include implementation of partial file systems virtualization and CPU isolation using CPU sets.

Brooks Davis - Using FreeBSD to Promote Open Source Development Methods
Using FreeBSD to Promote Open Source Development Methods In this talk we present Aerosource, an initiative to bring Open Source Software development methods to internal software developers at The Aerospace Corporation. Within Aerosource, FreeBSD is used in several key roles. First, we run most of our tools on top of FreeBSD. Second, the ports collection (both official ports and custom internal ones) eases our administrative burden. Third, the FreeBSD project serves as an example and role model for the results that can be achieved by an Open Source Software projects. We discuss the development infrastructure we have built for Aerosource based largely on BSD licensed software including FreeBSD, PostgreSQL, Apache, and Trac. We will also discuss our custom management tools including our system for managing our custom internal ports. Finally, we will cover our development successes and how we use projects like FreeBSD as exemplars of OSS development.
