SGI Tempo cluster management software is designed for rapid deployment, efficient scaling, and reliable operations in the most demanding HPC data centers. While leveraging available open source tools for familiar cluster operations, it also delivers innovation in several key areas. These areas include a scalable and reliable Hierarchical Management Framework (HMF) which speeds deployment while improving performance and resiliency of the management functions. In addition SGI Tempo provides an innovative approach to diskless boot operations which reduces overall memory capacity requirements for diskless servers and increases reliability of the compute node by alleviating the need for a local hard drive which is a common failure component.
