NOVA in the Linux Weekly News
The NOVA file system was recently written up in the Linux Weekly News.
NOVA's goal is to provide a high-performance, full-featured, production-ready file system tailored for byte-addressable non-volatile memories (e.g., NVDIMMs and Intel's soon-to-be-released 3DXpoint DIMMs). It combines design elements from many other file systems to provide a combination of high-performance, strong consistency guarantees, and comprehensive data protection.
Graduation Party!
NVSL students family and friends joined newly minted Drs. Yang "Robert" Liu, Meenakshi Sundaram Bhaskaran, Michael Wei, and Yanqin Jin for lunch before the graduation ceremony. We were especially happy to have so mayn of their parents and family members in attenance.
Another NVSL alumn, Akshatha Gangadharaiah, was also in the graduation ceremony.
Best of luck to all of you, and thank you for all your hard work! We will miss you!
Presenting Drs. Bhaskaran and Liu!
Yang "Robert" Liu and Meenakshi Sundaram Bhaskaran successfully defended their dissertations on the 9th and 8th of December, respectively. Robert's work on "Systems and Algorithm Support for Efficient Heterogeneous Computing with GPUs" broke new ground in integrating GPUs and conventional processors. Sundaram, in the meantime, developed new ways of integrating non-volatile memories into systems at multiple levels with "Micro-Architecture and Systems Support for Emerging Non-Volatile Memories."
Robert is headed to Western Digital. Sundaram is setting off on a great (and secret) adventure.
We will miss you both, and wish you all the best!
Hung Wei is a Professor at NCSU!
Our own Hung Wei Tseng has just started his new position at North Carolina State University. Hung Wei did his PhD at UCSD with Dean Tullsen and then joined my group as a post-doc.
Congratulations, Hung Wei!
NOVA Written up in Storage Mojo
Robin Harris, well-known storage blogger has put up a nice piece about NOVA and it's potential role in systems equipped with non-volatile main memory technologies like Intel's 3D XPoint. You can read about it here. Thanks Robin!
NVSL Releases NOVA, a File System for Non-volatile Main Memory
NOVA is a log-structured file system designed for byte-addressable, non-volatile memories. NOVA is fully POSIX compliant so that existing applications need not be modified to run on NOVA. NOVA bypasses the block layer and OS page cache, writes to NVM directly and reduces the software overhead.
NOVA combines a novel logging scheme and journalling to provide strong consistency guarantees, good scalability, and fast recovery time. NOVA maintains a private log for each iNode, allowing for concurrent accesses, updates, and recovery from system failures.
Andiry will present NOVA at the USENIX FAST conference in February.
Read the paper.
Congratulations Professor Zhang!
Dr. Yiying Zhang has just completed her post-doc in the NVSL and has moved to Purdue as an Assistant Professor. Hurray!
Steve Interviewed for USENIX ;Login:
Rik Farrow, editor of USENIX ;Login: (USENIX's technology magazine) interviewed Steven about the future of storage, where researchers can have the most impact in the area of SSDs, and the future non-volatile memories.
Michael Wei Receives NSF Graduate Research Fellowship
The NSF awards these fellowships across science, engineering, and math-related disciplines. They are very prestigious.
From the NSF web site: The National Science Foundation's Graduate Research Fellowship Program (GRFP) helps ensure the vitality of the human resource base of science and engineering in the United States and reinforces its diversity. The program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based master's and doctoral degrees at accredited US institutions.
Way to go, Michael!
