AutoGNN: End-to-End Hardware-Driven Graph Preprocessing for Enhanced GNN Performance
Seungkwan Kang, Seungjun Lee, Donghyun Gouk +9
Graph neural network (GNN) inference faces significant bottlenecks in preprocessing, which often dominate overall inference latency. We introduce AutoGNN, an FPGA-based accelerator…
A Survey on User-Space Storage and Its Implementations
Junzhe Li, Xiurui Pan, Shushu Yi +1
The storage stack in the traditional operating system is primarily optimized towards improving the CPU utilization and hiding the long I/O latency imposed by the slow I/O devices s…
Revamping Storage Class Memory With Hardware Automated Memory-Over-Storage Solution
Jie Zhang, Miryeong Kwon, Donghyun Gouk +4
Large persistent memories such as NVDIMM have been perceived as a disruptive memory technology, because they can maintain the state of a system even after a power failure and allow…
FastDrain: Removing Page Victimization Overheads in NVMe Storage Stack
Jie Zhang, Miryeong Kwon, Sanghyun Han +3
Host-side page victimizations can easily overflow the SSD internal buffer, which interferes I/O services of diverse user applications thereby degrading user-level experiences. To a…
ZnG: Architecting GPU Multi-Processors with New Flash for Scalable Data Analysis
Jie Zhang, Myoungsoo Jung
We propose ZnG, a new GPU-SSD integrated architecture, which can maximize the memory capacity in a GPU and address performance penalties imposed by an SSD. Specifically, ZnG replac…
Faster than Flash: An In-Depth Study of System Challenges for Emerging Ultra-Low Latency SSDs
Sungjoon Koh, Junhyeok Jang, Changrim Lee +3
Emerging storage systems with new flash exhibit ultra-low latency (ULL) that can address performance disparities between DRAM and conventional solid state drives (SSDs) in the memo…
Exploring Fault-Tolerant Erasure Codes for Scalable All-Flash Array Clusters
Sungjoon Koh, Jie Zhang, Miryeong Kwon +4
Large-scale systems with all-flash arrays have become increasingly common in many computing segments. To make such systems resilient, we can adopt erasure coding such as Reed-Solom…
FUSE: Fusing STT-MRAM into GPUs to Alleviate Off-Chip Memory Access Overheads
Jie Zhang, Myoungsoo Jung, Mahmut Taylan Kandemir
In this work, we propose FUSE, a novel GPU cache system that integrates spin-transfer torque magnetic random-access memory (STT-MRAM) into the on-chip L1D cache. FUSE can minimize…
Amber: Enabling Precise Full-System Simulation with Detailed Modeling of All SSD Resources
Donghyun Gouk, Miryeong Kwon, Jie Zhang +5
SSDs become a major storage component in modern memory hierarchies, and SSD research demands exploring future simulation-based studies by integrating SSD subsystems into a full-sys…
CIAO: Cache Interference-Aware Throughput-Oriented Architecture and Scheduling for GPUs
Jie Zhang, Shuwen Gao, Nam Sung Kim +1
A modern GPU aims to simultaneously execute more warps for higher Thread-Level Parallelism (TLP) and performance. When generating many memory requests, however, warps contend for l…
FlashAbacus: A Self-Governing Flash-Based Accelerator for Low-Power Systems
Jie Zhang, Myoungsoo Jung
Energy efficiency and computing flexibility are some of the primary design constraints of heterogeneous computing. In this paper, we present FlashAbacus, a data-processing accelera…
Understanding System Characteristics of Online Erasure Coding on Scalable, Distributed and Large-Scale SSD Array Systems
Sungjoon Koh, Jie Zhang, Miryeong Kwon +4
Large-scale systems with arrays of solid state disks (SSDs) have become increasingly common in many computing segments. To make such systems resilient, we can adopt erasure coding…
TraceTracker: Hardware/Software Co-Evaluation for Large-Scale I/O Workload Reconstruction
Miryeong Kwon, Jie Zhang, Gyuyoung Park +5
Block traces are widely used for system studies, model verifications, and design analyses in both industry and academia. While such traces include detailed block access patterns, e…
SimpleSSD: Modeling Solid State Drives for Holistic System Simulation
Myoungsoo Jung, Jie Zhang, Ahmed Abulila +5
Existing solid state drive (SSD) simulators unfortunately lack hardware and/or software architecture models. Consequently, they are far from capturing the critical features of cont…
