WaferTrans: Enabling IOMMU-free Distributed Virtual Address Translation for Wafer-scale GPUs
Xinru Tang, Jingxiang Hou, Guanghong Wu +2
Wafer-scale GPUs (WSGs) provide sufficient on-wafer bandwidth to make near-lossless Unified Memory feasible. However, existing designs still rely on a CPU-IOMMU to translate remote…

TEMP: A Memory Efficient Physical-aware Tensor Partition-Mapping Framework on Wafer-scale Chips
Huizheng Wang, Taiquan Wei, Zichuan Wang +8
Large language models (LLMs) demand significant memory and computation resources. Wafer-scale chips (WSCs) provide high computation power and die-to-die (D2D) bandwidth but face a…
