> Zymtrace: Zero-instrumentation continuous profiling for CPU and GPU workloads, providing actionable insights to optimize performance, debug faster & reduce cloud costs

Zymtrace is a distributed, zero-instrumentation continuous profiler for CPU and GPU workloads. It correlates GPU metrics, CUDA/SASS-level flamegraphs, and host CPU profiles to pinpoint bottlenecks in inference, training, and general-purpose code, then turns them into concrete optimization actions to improve throughput per GPU, per watt, and per dollar.
