The open web ran on an unwritten bargain: sites admitted crawlers, and search engines sent visitors back. Public measurements show that bargain breaking under AI crawlers and agent…
Hardware-Transparent I/O Governance in Disaggregated Heterogeneous Storage
Rajarshi Chowdhury, Akshay Shah, Sue K. Lee
Shared-nothing disaggregated storage clusters that serve both latency-sensitive databases and opaque block-volume workloads face two governance problems unsolved by existing schedu…
uringscope: Portable, Low-Overhead Observability for io_uring
Rajarshi Chowdhury
io_uring moves I/O submission and completion into shared-memory rings. This makes it fast, and it also makes it invisible. strace sees only the ring setup, and the kernel tracepoin…
