Sandia Line of LWKs

Sandia National Laboratories has been engaged in operating systems research for high-performance computing for more than two decades. The focus has always been extremely parallel systems and the most efficient systems software possible to complete the scientific work demanded by the laboratories’ mission. This chapter provides a chronological overview of the operating systems developed at Sandia and the University of New Mexico. Along the way we highlight why certain design decisions were made, what we have learned from our failures, and what has worked well. We summarize these lessons at the end of the chapter, but hope that the more detailed explanations in the text may be useful to future HPC OS designers.
