Detailed Description

Lightweight workload-aware policy for deciding whether an internal phase should actually launch parallel work when parallel mode is allowed.

The goal is to avoid forcing every short-lived loop onto the thread pool. Decisions are based on available worker capacity and on the amount of work already visible to the phase, instead of on buried per-loop split sizes.

Member Function Documentation

IsParallelAllowed()

static bool BRepGraph_ParallelPolicy::IsParallelAllowed ( const bool theAllowParallel )

inlinestatic

Check whether parallel execution is allowed and meaningful at all.

ShouldRun() [1/2]

static bool BRepGraph_ParallelPolicy::ShouldRun ( const bool theAllowParallel, const int theWorkers, const Workload & theWorkload )

inlinestatic

Decide whether the estimated workload is large enough to amortize thread-pool launch and synchronization overhead.

ShouldRun() [2/2]

static bool BRepGraph_ParallelPolicy::ShouldRun ( const bool theAllowParallel, const Workload & theWorkload )

inlinestatic

Overload that queries the active worker count lazily.

WorkerCount()

static int BRepGraph_ParallelPolicy::WorkerCount ( )

inlinestatic

Return the effective logical worker count reported by OSD_Parallel.
