Abstract
Evolving Modern Storage Stack: I/O Abstraction, Caching and Prefetching.
With the rise of AI and data-intensive applications, the storage stack has become a critical component for performance. At the same time, new storage hardware devices, such as near-storage accelerators, are emerging. However, the storage stack has struggled to keep pace, leading to significant performance bottlenecks. This talk focuses on our works on how to evolve the modern storage stack through three key pieces: I/O abstraction, caching, and prefetching. First, we introduce a new I/O abstraction to reduce dominant I/O overheads and efficiently utilize near-storage computing capabilities. Next, we present a novel caching management solution that spans host and storage devices, optimizing memory resources. Finally, we present a cross-layered (user-level runtime and OS) prefetching mechanism for optimal performance.
About the College of Computing
The Michigan Tech College of Computing, established in 2019, is the first academic unit in Michigan dedicated solely to computing, and one of only a handful such academic units in the United States. The college is composed of two academic departments. The Computer Science department offers four bachelor of science programs in computer science, cybersecurity, data science, and software engineering; four master of science programs in applied computer science, computer science, cybersecurity, and data science; and a doctoral program in computer science. The Applied Computing department offers four bachelor of science programs in cybersecurity, electrical engineering technology, information technology, and mechatronics; two master of science programs in health informatics and mechatronics; and a doctoral program is in computational science and engineering.
