The recent rise of byte-addressable non-volatile memory technologies is blurring the
dichotomy between memory and storage. In particular, they allow programmers to have …

This paper presents PPA (Persistent Processor Architecture), simple microarchitectural
support for lightweight yet performant whole-system persistence. PPA offers fully transparent …

Persistency models define the persist-order that controls the order in which stores update
persistent memory (PM). As with memory consistency, the relaxed persistency models …

This paper investigates whole-system persistence (WSP) that ensures hassle-free crash
consistency for all programs while simultaneously leveraging both advantages of the non …

Computer systems designers are building cache hierarchies with higher capacity to capture
the ever-increasing working sets of modern workloads. Cache hierarchies with higher …

Persistent memory enables a new class of applications that have persistent in-memory data
structures. Recoverability of these applications imposes constraints on the ordering of writes …

Nonvolatile memory (NVM) technologies have gained increasing attention thanks to their
density and durability benefits. However, leveraging NVM can cause a crash consistency …

Byte-addressable non-volatile memory (NVM) is a promising technology that provides near-
DRAM performance with scalable memory capacity. However, it requires atomic data …

As cloud workloads increasingly adopt the fault-tolerant Function-as-a-Service (FaaS)
model, demand for improved performance has increased. Alas, the performance of FaaS …

Supporting atomic durability of updates for persistent memories is typically achieved with
Write-Ahead Logging (WAL). WAL flushes log entries to persistent memory before making …
