MPI-over-CXL: Enhancing Communication Efficiency in Distributed HPC Systems
Miryeong Kwon, Donghyun Gouk, Hyein Woo +10
MPI implementations commonly rely on explicit memory-copy operations, incurring overhead from redundant data movement and buffer management. This overhead notably impacts HPC workl…

From Block to Byte: Transforming PCIe SSDs with CXL Memory Protocol and Instruction Annotation
Miryeong Kwon, Donghyun Gouk, Junhyeok Jang +8
This paper explores how Compute Express Link (CXL) can transform PCIe-based block storage into a scalable, byte-addressable working memory. We address the challenges of adapting bl…

CXL Topology-Aware and Expander-Driven Prefetching: Unlocking SSD Performance
Dongsuk Oh, Miryeong Kwon, Jiseon Kim +8
Integrating compute express link (CXL) with SSDs allows scalable access to large memory but has slower speeds than DRAMs. We present ExPAND, an expander-driven CXL prefetcher that…
