    <div class="sphx-glr-thumbcontainer" tooltip="Parallel-region profiling is disabled by default. This example enables it with a bounded collector, runs an Abs model, and inspects an immutable report. Passing hardware_counters=True explicitly requests the Linux grouped perf_event_open backend. Linux may require CAP_PERFMON or a permissive kernel.perf_event_paranoid setting. The backend rejects rather than scales multiplexed groups, so derived metrics exist only when time_running equals time_enabled. It also marks multi-thread regions unsuitable because a thread-bound perf group cannot represent their aggregate work. Unsupported platforms and denied counters retain portable timing; None is distinct from a valid zero.">
