TL;DR
Bounded Reclamation of User-space Memory Mappings makes reclamation latency a first-class resource that can be accounted for, thereby improving isolation and reliability in edge clouds.
Edge computing solutions have become a crucial part of the industry, delivering fast, flexible and scalable applications close to the end users, with typical use cases including dynamic content creation, image resizing and chatbots. Cloudflare Workers is one such framework, which handles millions of HTTP requests per s...
When the aggregate working set of active processes exceeds physical RAM capacity, the machine experiences memory pressure. Applications may therefore slow down before the kernel kills a process. Linux provides several ways to observe and respond: Pressure Stall Information (PSI) can detect memory-related task stalls, z...
SerMC is proposed, a memory-controller-based tripwire mechanism that validates accesses when metadata arrives from Dynamic Random Access Memory and extends enforcement to DRAM-bound accesses issued by both processors and DMA-capable devices, and provides practical average-case overhead but still exposes a clear worst-c...
SmartNICs promise hardware offloading for network applications like traffic analysis and virtual host dispatching. However, due to memory bandwidth limitations, SmartNICs are unable to effectively accelerate applications like intrusion detection and deep packet inspection that require high-speed reassembly. We argue th...
