XPR: An Extensible Cross-Platform Point-Based Differentiable Renderer
Steve Rhyner, Sankeerth Durvasula, Aleksandr Kovalev +7
Point-based differentiable rendering underpins modern 3D reconstruction, novel-view synthesis, and learning-based graphics pipelines, but developing new rendering methods often req…
RowPress Vulnerability in Modern DRAM Chips
Haocong Luo, Ataberk Olgun, A. Giray Yağlıkçı +6
Memory isolation is a critical property for system reliability, security, and safety. We demonstrate RowPress, a DRAM read disturbance phenomenon different from the well-known RowH…
PIM-Opt: Demystifying Distributed Optimization Algorithms on a Real-World Processing-In-Memory System
Steve Rhyner, Haocong Luo, Juan Gómez-Luna +6
Modern Machine Learning (ML) training on large-scale datasets is a very time-consuming workload. It relies on the optimization algorithm Stochastic Gradient Descent (SGD) due to it…
Read Disturbance in High Bandwidth Memory: A Detailed Experimental Study on HBM2 DRAM Chips
Ataberk Olgun, Majd Osseiran, Abdullah Giray Yaglikci +6
We experimentally demonstrate the effects of read disturbance (RowHammer and RowPress) and uncover the inner workings of undocumented read disturbance defense mechanisms in High Ba…
ABACuS: All-Bank Activation Counters for Scalable and Low Overhead RowHammer Mitigation
Ataberk Olgun, Yahya Can Tugrul, Nisa Bostanci +6
We introduce ABACuS, a new low-cost hardware-counter-based RowHammer mitigation technique that performance-, energy-, and area-efficiently scales with worsening RowHammer vulnerabi…
