MCP Shows What the Agent Did. eBPF Shows Why the GPU Stalled.

14h ago · 9 min read · MCP exposes the agent’s tool calls. eBPF exposes the kernel events that explain why those tool calls returned what they returned. TL;DR The Model Context Protocol (MCP) is converging on an industry st

nvidia-smi Reports 97% Utilization While the GPU Sits Idle

1d ago · 3 min read · TL;DR A GPU shows 97% utilization in nvidia-smi, but training throughput is a fraction of what benchmarks promise. The GPU is not computing; it is waiting. Data loading workers are starving the traini

Catching a vLLM Latency Spike with eBPF and an Open-Weight LLM

4d ago · 7 min read · TL;DR A vLLM latency spike was debugged using a fully open source stack: eBPF kernel tracing + MiniMax M2.7 (open-weight model via Ollama) + MCP (open protocol). The AI autonomously called 4 tools, i

MCP Tools Are New API Surfaces. eBPF Sees What They Actually Touch.

5d ago · 4 min read · An MCP tool call is a tiny line of agent code that fans out to syscalls, library calls, and kernel paths the agent has no view of. TL;DR Through April and early May, vendors shipped MCP servers in bat

A Cluster Stall Looks Healthy on Every Host. The Cause Is in the Pattern Across Hosts.

6d ago · 11 min read · Eight ranks on two hosts. Every per-host metric reads healthy. Rank 5 enters the barrier 290ms late. The cause lives in a cross-rank query, not in any single host’s trace. TL;DR Eight ranks on two hos
