Over the past five years we have built and operated a computing cluster for company-wide unclassified technical and scientific computing. In this paper, we discuss our cluster architecture, some of the architectural decisions we faced in the process, a sampling of applications run by our users, and lessons learned from building and operating this cluster.(More)
In this paper we discuss the design and implementation of Fellowship, a 300+ CPU, general use computing cluster based on FreeBSD. We address the design features including configuration management, network booting of nodes, and scheduling which make this cluster unique and how FreeBSD helped (and hindered) our efforts to make this design a reality.
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 In-tel Pentium III systems to our current mix of 64 dual Intel Xeon and 289 dual AMD Opteron systems. This paper looks back on the system architecture as(More)
The advent of affordable high performance computing (HPC) resources, such as computing clusters and grids, has transformed the computational capabilities of many organizations. However, the lack of convenient interfaces to such valuable resources limits their effectiveness, restricting their user base to a small set of highly skilled programmers and(More)
