Explanation
For [
#7773], the FIFO, MC, and LIFO work-requesting schedulers passnuma_sensitive_modeinto their initialization. Each worker builds separate same-domain and permitted remote victim masks. Victim requests use same-domain victims first and use eligible remote domains afterward. The NUMA helper implements levels 0, 1, and 2.set_scheduler_modeno longer forcesenable_stealing_numa. The added victim-mask, domain-selection, and scheduler-mode tests cover the requested behavior. The command-line help and manual document the work-requesting schedulers.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winDocument all NUMA sensitivity levels for ABP and work-requesting schedulers.
The ABP scheduler checks same-domain queues first, but level 1 also restricts cross-domain stealing to boundary workers and nearest domains. Level 2 disables remote stealing. The work-requesting scheduler applies the same level policy to its local and remote victim masks. Update both sections as follows:
📝 Suggested documentation update
queue from which threads will be scheduled only when there is no other work. For -this scheduling policy there is an option to turn on NUMA sensitivity using the -command line option :option:`--hpx:numa-sensitive`. When NUMA sensitivity -is turned on work stealing is done from queues associated with the same NUMA -domain first, only after that work is stolen from other NUMA domains. +this scheduling policy the command line option +:option:`--hpx:numa-sensitive` controls NUMA-sensitive work stealing. The +scheduler checks queues in the same NUMA domain first. At level ``0`` all +workers may then steal across NUMA domains. At the default level ``1`` only +boundary workers may steal from the nearest NUMA domains. At level ``2`` +workers may not steal across NUMA domains. @@ In general, this scheme avoids contention on the work queues as those are always accessed by their own cores only. +Requests first try workers in the same NUMA domain. At level ``0`` all workers +may request work across NUMA domains. At the default level ``1`` only boundary +workers may request work from the nearest NUMA domains. At level ``2`` workers +may not request work across NUMA domains.🤖 Prompt for AI Agents

Fixes #7773
Proposed Changes

This PR is stacked on #7756 because it uses the three-level
numa_sensitive_modeand the shared distance-ordered NUMA-domain helper introduced there. Once #7756 merges, this branch can be rebased so that only the three work-requesting commits remain.Validation:
HPX_WITH_WORK_REQUESTING_SCHEDULERS=ONworkrequesting_numa,workrequesting_random_victim,workrequesting_scheduler_mode,workrequesting_steal, andworkrequesting_suspend_resumepassThe complete scheduler unit group passes 15/16 in this configuration. The remaining
min_tasks_to_steal_stagedfailure is issue #7772 and is fixed separately by #7777.Checklist
