 Building a High-Performance Computing Cluster Using FreeBSD

 6:30pm, Suspenders Restaurant

 Special NYC*BUG meeting with FreeBSD developer Brooks Davis

 Please note that this meeting is not on our normal first
 Wednesday of the month, and that we will not be adjusting our
 other meetings

 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.


 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.
