   USM turns idle NVIDIA VRAM into Linux swap

   USM is a beta, NVIDIA-only Linux project that uses a user-space daemon to borrow idle VRAM through CUDA and expose it as a high-priority swap device through ublk, without requiring a kernel module. Developer kha333n reports that 5.5 GiB of VRAM with lz4 compression held about 16 GiB of application memory and averaged roughly 9 microseconds per page fault, versus about 55 microseconds plus overhead for NVMe. The project was tested on Ubuntu 26.04 with two laptops, and most of its code was written with Claude Code.

   Lenovo touts pooled memory plus near-memory computing to ease KV cache strain

   TMTpost reports that a Lenovo team led by chief scientist Xiao Limin has built a compute-storage fusion pooled system combining memory pooling with near-memory computing to address two inference pain points: insufficient GPU and CPU-attached memory for KV cache, and high-cost GPU access to external storage. The team places the system at a "G2.5" stage and describes vendor self-tests. Versus NVMe-tier pooling, memory-pool offloading cut first-token latency by 3.5x at fixed input length and 2.4x in multi-turn dialogue. Cross-instance KV reuse accelerated first-token latency by up to 12–28x versus full recomputation and 2–3x versus an RDMA distributed memory pool. Offloading attention computation to the memory-pool side cut decode latency by 2.5x, and end-to-end inference latency was 2–3x faster than the RDMA pool, with system throughput 6–20x higher as context lengthened. Lenovo plans to move from G2.5 toward G1.5 using scale-up interconnects in supernodes. Xiao said he has not seen a product that brings near-memory computing into a large-capacity memory pool to address both KV cache capacity and access overhead; no independent third-party verification was reported.

   FADU Moves File Operations Into SSD Firmware

   FADU unveiled its File-Semantic SSD (FS-SSD) at the 2026 OCP Global Summit, moving path lookup, access checks, and file-to-flash mapping into the drive while carrying NFSv3 operations in standard NVMe commands. In FADU's preliminary vendor test, a Gen6 FC6161 drive in a PCIe 5.0 host maintained about 460,000 remote file operations per second as the server was reduced from what FADU labels as 16 cores to one. The company expects PCIe 6.0 Gen6-host results by Q1 2027. The current software lacks features including ACLs, and FADU has not submitted a file-semantic command set to NVM Express or OCP Storage.
