Operating system issues for petascale systems
Pete Beckman, Kamil A. Iskra, Kazutomo Yoshii, Susan Coghlan · ACM SIGOPS Operating Systems Review · 2006
Petascale supercomputers will be available by 2008. The largest machine of these complex leadership-class machines will probably have nearly 250K CPUs. These massively parallel systems have a number of challenging operating system issues. In this paper, we focus on the issues most important for the system that will first breach the petaflop barrier: synchronization and collective operations, parallel I/O, and fault tolerance.
