Cold memory rebalancing exhibits unique challenges to the existing memory overcommitment mechanisms, such as page tracking under Transparent Huge Pages (THP) and frequent remapping of page tables, leading to a series of throughput and latency issues. In this paper, we propose Blowfish, a memory o...

Enterprise SSDs integrate substantial computing resources (e.g., ARM processor and onboard DRAM) to handle I/O bursts. However, these resources significantly raise SSD monetary cost and suffer severely underutilized in JBOF deployments due to the sporadic nature of I/O bursts. In this paper, we p...

Modern GPU workloads increasingly rely on dynamic and fine-grained memory allocation, yet GPU memory management remains CPU-centric. In current GPU runtimes, allocation metadata updates, page-table construction, translation-state propagation, and TLB shootdowns are largely serialized through the...
