CoCoA: An in-CXL Switch Collective Communication Accelerator

The Message Passing Interface (MPI) is widely adopted in high-performance computing (HPC) systems to support scalable inter-process communication. While HPC systems are theoretically expected to offer high performance, they often fall short in practice due to the overhead from MPI. In particular, MPI collective communi...

Accelerating Data Preprocessing for Efficient Vision Model Inference on Jetson Edge Device

Data preprocessing is a crucial part of deep learning workflows on edge devices. However, decoding data saved in JPEG format is very compute-intensive and occupies a major portion of the preprocessing pipeline. Therefore, increasing the decoding speed is vital for improving overall throughput, especially for inputs wit...

HAT-MPI: Hierarchical Auto Tuning of MPI Inter-Node Communication on InfiniBand Clusters

This work presents HAT-MPI, an ML-based framework that identifies the UCX Eager-Rendezvous protocol threshold and the optimal collective algorithm on InfiniBand HPC clusters and introduces two complementary techniques that improve the conventional data collection and evaluation workflow, namely LLM-assisted HPC hardwar...
