Source Known Identifiers: A Three-Tier Identity System for Distributed Applications

A multi-paper arXiv feed covering advances in distributed systems, HPC, and ML infrastructure. Key contributions include: SKIDs — a three-tier identifier system (64-bit SKID, 128-bit SKEID with BLAKE3 MAC, and an AES-256-encrypted Secure SKEID) designed for compactness, chronological ordering, zero-lookup origin verification and external confidentiality; NIMBLE and TENT — runtime orchestration/data-plane systems for dynamic multi-path balancing and slice-spraying across heterogeneous intra-node and inter-node GPU interconnects (NVLink, multi-rail RDMA) to improve throughput and fault recovery;
