CACHEFORGE: LLM-Guided End-to-End Generative Cache Replacement Policy for Performance and Hardware Efficiency

Kaushal Mhapsekar, Bita Aslrousta, Brijesh Kumar Bhayana +5

Modern cache replacement designs saturate because they operate within fixed representational structures, hand-crafted and heuristic based feature-engineered predictors, or offline…

CacheFit: The Rising Cost of Cache Replacement and Constraint-Driven Redesign of Last-Level Cache Replacement Policies

Bita Aslrousta, Kaushal Mhapsekar, Darsh Asher +3

The latency, power, and area costs of LLC replacement remain poorly explored not because simulators cannot be instrumented--event counters feeding a power model are routine--but be…

TranScope: What the Software Hides About LLM Training Data, the Hardware Reveals at Scale, and Accelerators Magnify

Joshua Kalyanapu, Darsh Asher, Kaushal Mhapsekar +5

Membership is the root privacy primitive in machine learning: to date, no hardware-based out-of-distribution detection on black-box models has been demonstrated against constant-ti…

An Attack on The Speculative Vectorization: Leakage from Higher Dimensional Speculation

Sayinath Karuppanan, Samira Mirbagher Ajorpaz

This paper argues and shows that speculative vectorization, where a loop with rare or unknown memory dependencies are still vectorized, is fundamentally vulnerable and cannot be mi…
