Practical DB-OS Co-Design with Privileged Kernel Bypass

Zhou, Xinjing; Leis, Viktor; Hu, Jinming; Yu, Xiangyao; Stonebraker, Michael (ACM, 2025-02-11)

This paper revisits the longstanding challenge of coordinating database systems with general-purpose OS interfaces, such as POSIX, which often lack tailored support for DB requirements. Existing approaches to this DB-OS ...
SySTeC: A Symmetric Sparse Tensor Compiler

Patel, Radha; Ahrens, Willow; Amarasinghe, Saman (ACM|Proceedings of the 23rd ACM/IEEE International Symposium on Code Generation and Optimization, 2025-03-01)

Symmetric and sparse tensors arise naturally in many domains including linear algebra, statistics, physics, chemistry, and graph theory. Symmetric tensors are equal to their transposes, so in the n-dimensional case we can ...
FHE-Rollups: Scaling Confidential Smart Contracts on Ethereum and Beyond

Zyskind, Guy; Erez, Yonatan; Langer, Tom; Grossman, Itzik; Bondarevsky, Lior (ACM|The 6th ACM International Symposium on Blockchain and Secure Critical Infrastructure, 2024-07-02)

Blockchains ensure that all transactions, including those that execute deterministic programs known as smart contracts, are processed correctly and without interruption. However, blockchains inherently provide no confidentiality ...
