Best Paper Award at IEEE NVMSA 2018

UNIST CSE J. Hyun Kim, Young Je Moon, Hyunsub Song, Jay H. Park and Professor Sam H. Noh’s paper “μSnap: Embracing Traditional Programming Models
for Persistent Memory through OS Support” received the Best Paper Award at IEEE NVMSA 2018.

μSnap is an operating system support that is based on checkpointing that allows legacy applications to be executed as-is in a persistent memory environment without compromising consistency.
The overhead of μSnap for a wide range of applications turned out to be small and this small cost can be tremendous in the sense that one can transparently guarantee the consistency of all legacy software written under the traditional programming model.

NVMSA is a major international conference for new ideas and research results in the area of non-volatile memory systems and emerging memory technologies.

Paper accepted at MICRO 2018

UNIST CSE CISSR team, NECSST lab researcher Sekwon Lee and Professor Sam H. Noh’s paper entitled “iDO: Compiler-Directed Failure Atomicity for Nonvolatile Memory” has been accepted to MICRO 2018. This work was done in collaboration with Virginia Tech and the University of Rochester.
This paper presents iDO, a compiler-directed approach to failure atomicity with nonvolatile memory. The iDO compiler identifies idempotent instruction sequences, whose re-execution is guaranteed to be sideeffect-free, thereby eliminating the need to log every persistent store.
IEEE/ACM MICRO is one of the world’s best symposium in the field of computer architecture. This symposium brings together researchers in fields related to microarchitecture, compilers, chips, and systems for technical exchange on traditional microarchitecture topics and emerging research areas.
