Blackcomb 2: Hardware-Software Co-design for Non-Volatile Memory in Exascale Systems
- Hewlett Packard Enterprise, Palo Alto, CA (United States)
Fast non-volatile memory (NVM) offers game-changing opportunities to rethink traditional system architectures; to address their energy inefficiencies; to leverage the new devices for greater performance; and to exploit the new capability of non-volatility to enhance system resilience, even in the face of larger system scale and degraded reliability of components. However, the devil is in the details, and to reap such potential benefits we must address challenges that arise when the contents of memory survive application failure, when software becomes responsible for managing the contents of CPU caches, and when memory accelerators blur the line between hardware and software. Building on the accomplishments of the Blackcomb Project, funded in 2010, we have identified, evaluated, and optimized promising NVM hardware and software technologies that are essential to provide the necessary memory capacity, performance, resilience, and energy efficiency in exascale systems.
