This value can be changes at runtime by setting the configuration parameter:

hpx.agas.local_cache_size = …

(or by setting the corresponding environment variable HPX_AGAS_LOCAL_CACHE_SIZE)

HPX_INITIAL_AGAS_MAX_PENDING_REFCNT_REQUESTS
HPX_GLOBALCREDIT_INITIAL

This defines the initial global reference count associated with any created object.

HPX_NUM_IO_POOL_SIZE

This defines the default number of OS-threads created for the different internal thread pools

HPX_NUM_PARCEL_POOL_SIZE
HPX_NUM_TIMER_POOL_SIZE
HPX_SPINLOCK_DEADLOCK_DETECTION_LIMIT

By default, enable minimal thread deadlock detection in debug builds only.

HPX_COROUTINE_NUM_HEAPS

This defines the default number of coroutine heaps.

HPX_HAVE_THREAD_BACKTRACE_DEPTH

By default, enable storing the thread phase in debug builds only.

By default, enable storing the parent thread information in debug builds only.By default, enable storing the thread description in debug builds only. By default, enable storing the target address of the data the thread is accessing in debug builds only. By default we do not maintain stack back-traces on suspension. This is a pure debugging aid to be able to see in the debugger where a suspended thread got stuck. By default we capture only 5 levels of stack back trace on suspension
