Automating Performance Bottleneck Identification with the TraceLens Agent
- 30 September 2026
GPUs are valuable resources, and it is imperative to make training and inference workloads on them as efficient as possible. Bottlenecks in these workloads can arise from multiple sources, and mitigations vary depending on the source. For example, a kernel may execute well below its achievable throughput, a collective may remain exposed on the critical path, or the device may sit idle while waiting on host-side dispatch. Identifying these bottlenecks is the first step to improving end-to-end performance.
TraceLens: Democratizing AI Performance Analysis
- 27 April 2026
Profiling modern AI workloads produces huge traces that are hard to interpret. Framework profilers record thousands of operations, kernels, and communication events, and engineers often end up staring at tools like Perfetto UI doing manual calculations. TraceLens speeds this up: it consumes existing framework traces and turns them into structured summaries and comparisons, allowing you to move on to the actual diagnosis and optimization.
