NVM-enabled Host-side Caches

The goals of this NVM Caching project are to:

  • develop selective caching algorithms that better utilize non-datapath NVM caches on the host,
  • develop a model for component availability and failure domains leading to a fault-tolerant write caching design for systems,
  • develop co-operative cache partitioning techniques for DRAM and NVM enabled caches, and
  • develop data reduction techniques for host-side NVM caches.
