Abstract: 

This presentation from the PIRL 2020 conference is by David Teksen Aksun of EPFL Intel has released Intel Optane PM in 2019. Instead of emulation techniques, we can use Optane to evaluate previous design approaches for building durable data structures. In this talk, we focus on the in cache line logging (Incll) approach, which puts a log inside a cache line to avoid cache line write-backs in the critical path of the application, as a suitable example. We evaluate Incll with Intel Optane to show that it is a good time to reconsider previous design ideas as Optane characteristics are important. We leave the solution, which uses Optane efficiently, for another talk.
