The deeper lesson: NIST and ISO mandate independent adversarial testing for a reason.https://ure.us/articles/gpu-fleet-aiops-llm-backend-benchmark/Tue, 07 Apr 2026 00:00:00 +0000https://ure.us/articles/gpu-fleet-aiops-llm-backend-benchmark/Benchmarking seven LLM backends as autonomous operators for an 8,000-GPU cluster with six realistic failure scenarios and deterministic checklist scoring.https://ure.us/articles/context-drift-kills-agents-before-latency/Wed, 11 Mar 2026 00:00:00 +0000https://ure.us/articles/context-drift-kills-agents-before-latency/LLM agents on remote hosts drown in unfiltered SSH output. Context drift -- not latency, not cost -- is what kills autonomous fleet operations at scale.https://ure.us/articles/best-local-llm-scaling-coding-swarms/Mon, 09 Mar 2026 00:00:00 +0000https://ure.us/articles/best-local-llm-scaling-coding-swarms/Per-task throughput plateaus at four concurrent agents and holds flat through eight. Agents five through eight are free. The contention wall is a floor.https://ure.us/articles/best-local-llm-coding-agent-swarm/Sat, 07 Mar 2026 00:00:00 +0000https://ure.us/articles/best-local-llm-coding-agent-swarm/MoE is 4.9x faster than Dense when four coding agents share one GPU.

Twenty years later, the same physics governs GPU infrastructure.https://ure.us/articles/predictive-power-conditioning-gpu-clusters/Thu, 18 Dec 2025 00:00:00 +0000https://ure.us/articles/predictive-power-conditioning-gpu-clusters/GPU clusters fail on transitions, not sustained load. Predicting step-loads from workload telemetry helps pre-position power controls and reduce surprise.https://ure.us/articles/hvac-doesnt-create-cold-removes-heat/Sun, 07 Dec 2025 00:00:00 +0000https://ure.us/articles/hvac-doesnt-create-cold-removes-heat/This is the first in a series on thermal management in data center environments. Cooling isn't magic - it's heat removal, at scale.
