Green Cryptography and Other Optimisations
The spectral decomposition of cryptography into its life-giving components yields an interlaced network oftangential and orthogonal disciplines that are nonetheless invariably grounded by the same denominator: theirimplementation on commodity computing pla ...
EPFL2023Imprecise Store Exceptions
Babak Falsafi, Mathias Josef Payer, Yuanlong Li, Siddharth Gupta, Yunho Oh, Qingxuan Kang, Abhishek Bhattacharjee
Precise exceptions are a cornerstone of modern computing as they provide the abstraction of sequential instruction execution to programmers while accommodating microarchitectural optimizations. However, increasing compute capabilities in deep memory hierar ...
ACM2023Instruction-Level Power Side-Channel Leakage Evaluation of Soft-Core CPUs on Shared FPGAs
Mathias Josef Payer, Mirjana Stojilovic, Shashwat Shrivastava, Ognjen Glamocanin, Jinwei Yao, Nour Ardo
Side-channel disassembly attacks recover CPU instructions from power or electromagnetic side-channel traces measured during code execution. These attacks typically rely on physical access, proximity to the victim device, and high sampling rate measuring in ...
2023Electrical-Level Attacks on CPUs, FPGAs, and GPUs: Survey and Implications in the Heterogeneous Era
Mirjana Stojilovic, Dina Gamaleldin Ahmed Shawky Mahmoud
Given the need for efficient high-performance computing, computer architectures combining CPUs, GPUs, and FPGAs are nowadays prevalent. However, each of these components suffers from electrical-level security risks. Moving to heterogeneous systems, with th ...
2022Do Children Adapt Their Perspective to a Robot When They Fail to Complete a Task?
Pierre Dillenbourg, Elmira Yadollahi, Ana Paiva
Spatial understanding and communication are essential skills in human interaction. An adequate understanding of others' spatial perspectives can increase the quality of the interaction, both perceptually and cognitively. In this paper, we take the first st ...
New York2022Micro-architectural analysis of in-memory OLTP: Revisited
Anastasia Ailamaki, Danica Porobic, Utku Sirin
Micro-architectural behavior of traditional disk-based online transaction processing (OLTP) systems has been investigated extensively over the past couple of decades. Results show that traditional OLTP systems mostly under-utilize the available micro-archi ...
2021Contextual Semi-Supervised Learning: An Approach To Leverage Air-Surveillance and Untranscribed ATC Data in ASR Systems
Petr Motlicek, Juan Pablo Zuluaga Gomez, Amrutha Prasad
Air traffic management and specifically air-traffic control (ATC) rely mostly on voice communications between Air Traffic Controllers (ATCos) and pilots. In most cases, these voice communications follow a well-defined grammar that could be leveraged in Aut ...
ISCA-INT SPEECH COMMUNICATION ASSOC2021Distributed Logless Atomic Durability with Persistent Memory
Babak Falsafi, Alexandros Daglis, Siddharth Gupta
Datacenter operators have started deploying Persistent Memory (PM), leveraging its combination of fast access and persistence for significant performance gains. A key challenge for PM-aware software is to maintain high performance while achieving atomic du ...
2019Improving Main-memory Database System Performance through Cooperative Multitasking
Database systems access memory either sequentially or randomly. Contrary to sequential access and despite the extensive efforts of
computer architects, compiler writers, and system builders, random access to data larger than the processor cache has been s ...
