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 paper we discuss the problem space
and our efforts so far. These efforts include
implementation of partial file systems vitalization
and CPU isolation using CPU sets.

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.

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.

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.
