TELLER Enables Cross-Layer Root-Cause Analysis for LLM Inference

TELLER addresses the challenge of root-cause analysis in large language model inference by providing non-intrusive cross-layer diagnostics across the inference engine, backend, CUDA APIs, GPU kernels, and distributed communication. This approach improves on existing profilers and log-based methods...

AI-assisted summary based on the listed source.

Large language model (LLM) inference has evolved from an offline workload into a continuously operated software service, yet root-cause analysis remains difficult because a single request spans the inference engine, Python/C++ backend, host CUDA APIs, GPU kernels, and distributed communication. Existing profilers...

As LLM inference shifts to continuous service operation, understanding performance bottlenecks and failures across complex software and hardware stacks is critical. TELLER's cross-layer analysis helps developers pinpoint issues more effectively, enhancing reliability and efficiency.

Hardware and robotics watchers may want to track whether this becomes a product, benchmark, or deployment signal.
