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.

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.
