“WineFS: a hugepage-aware file system for persistent memory that ages gracefully” is the title of the new paper presented at the 28th ACM Symposium on Operating Systems Principles (SOSP).

The new paper, written under the scope of the BigHPC Project, is focused on how a novel hugepage-aware PM file system can eliminate the effect of modern persistent-memory’s (PM) performance degrading significantly with usage.

According to the authors, “WineFS combines a new alignment-aware allocator with fragmentation-avoiding approaches to consistency and concurrency to preserve the ability to use hugepages”. Results show that WineFS can, not only resist the effect of aging, but also outperform state-of-the-art PM file systems in un-aged or aged settings.

The paper was presented at the ACM SOSP 2021 on the 29th and 30th of October, a forum for researchers, developers, programmers and teacher of computer systems technology from around the world. This year’s event was conducted virtually, with content delivered through Zoom webinars.

The authors of the paper were Rohan Kadekodi from the University of Texas at Austin, Saurabh Kadekodi from Carnegie Mellon University, Soujanya Ponnapalli from University of Texas at Austin, Harshad Shirwadkar from Google, Greg Ganger from Carnegie Mellon University, Aasheesh Kolli from Penn State University and VMware Research, Vijay Chidambaram from University of Texas at Austin and VMware Research.
