A Barrier-Free Synchronization Algorithm for Multi-Engine AI Accelerators
Chungha Sung, Nikil V. Shyamsunder, Hanliang Zhang +2
Multi-engine AI accelerators such as AWS Trainium comprise specialized compute engines that execute in parallel, and the compiler must synchronize the data dependencies between the…
Conflict Extraction in Probabilistic Datalog Analyses
Siyu Chen, Chungha Sung, Xuyang Li +1
Probabilistic extensions of Datalog enable static analyses such as pointer analysis, data race detection, and side-channel analysis to rank alarms by likelihood, but this added exp…
Axon: A Synthesizing Superoptimizer for Tensor Programs
Akash Kothari, Shaowei Zhu, Daniel Kroening +1
Writing high performance kernels for AI accelerators requires deep expertise in tiling, instruction selection, data layout, and operator fusion placing a significant burden on prog…
Data-Driven Synthesis of Provably Sound Side Channel Analyses
Jingbo Wang, Chungha Sung, Mukund Raghothaman +1
We propose a data-driven method for synthesizing a static analyzer to detect side-channel information leaks in cryptographic software. Compared to the conventional way of manually…
Debreach: Mitigating Compression Side Channels via Static Analysis and Transformation
Brandon Paulsen, Chungha Sung, Peter A. H. Peterson +1
Compression is an emerging source of exploitable side-channel leakage that threatens data security, particularly in web applications where compression is indispensable for performa…
Mitigating Power Side Channels during Compilation
Jingbo Wang, Chungha Sung, Chao Wang
The code generation modules inside modern compilers such as GCC and LLVM, which use a limited number of CPU registers to store a large number of program variables, may introduce si…
Datalog-based Scalable Semantic Diffing of Concurrent Programs
Chungha Sung, Shuvendu Lahiri, Constantin Enea +1
When an evolving program is modified to address issues related to thread synchronization, there is a need to confirm the change is correct, i.e., it does not introduce unexpected b…
CANAL: A Cache Timing Analysis Framework via LLVM Transformation
Chungha Sung, Brandon Paulsen, Chao Wang
A unified modeling framework for non-functional properties of a program is essential for research in software analysis and verification, since it reduces burdens on individual rese…
Modular Verification of Interrupt-Driven Software
Chungha Sung, Markus Kusano, Chao Wang
Interrupts have been widely used in safety-critical computer systems to handle outside stimuli and interact with the hardware, but reasoning about interrupt-driven software remains…
