InkStream: Real-time GNN Inference on Streaming Graphs via Incremental Update

no code implementations20 Sep 2023 Dan Wu, Zhaoying Li, Tulika Mitra

Our experiments with three GNN models on four large graphs demonstrate that InkStream accelerates by 2. 5-427$\times$ on a CPU cluster and 2. 4-343$\times$ on two different GPU clusters while producing identical outputs as GNN model inference on the latest graph snapshot.

Neural Network Inference on Mobile SoCs

no code implementations24 Aug 2019 Siqi Wang, Anuj Pathania, Tulika Mitra

Mobile devices are empowered with heterogeneous multi-processor Systems-on-Chips (SoCs) to process ML workloads such as Convolutional Neural Network (CNN) inference.

oo7: Low-overhead Defense against Spectre Attacks via Program Analysis

2 code implementations16 Jul 2018 Guanhua Wang, Sudipta Chattopadhyay, Ivan Gotovchits, Tulika Mitra, Abhik Roychoudhury

In this paper, we propose oo7, a static analysis approach that can mitigate Spectre attacks by detecting potentially vulnerable code snippets in program binaries and protecting them against the attack by patching them.
