@diehlpk Yes, this is expected. We have disabled the schedulers that depend on 128bit atomics on platforms where those are either not available or are not lockfree. We have seen large performance regressions in those cases (especially on ARM).
We're currently working in a fix, at least for x64 systems. ARM would be another matter to be addressed separately.
Expected Behavior
Command line option
--hpx:queuing=local-priority-lifo
worked with HPX 1.9.1 on Arm.Actual Behavior
Command line option --hpx:queuing=local-priority-lifo is not configured in this build. Please make sure 128bit atomics are available.
