  Persistent Memory Programming: DAX Mappings, PMDK Libraries, Crash Consistency Without Write-Ahead Logging, and the Optane Legacy

  2021-06-14

  A deep exploration of persistent memory — how DAX enables direct byte-addressable access to non-volatile memory, how the PMDK libraries solve the crash consistency problem at the instruction level, and the lessons of Intel Optane.
