Functions Documentation​

function shouldYieldDynamicWaitThread​

bool shouldYieldDynamicWaitThread(
    uint64_t spin_iteration,
    uint64_t spin_mask
)

function shouldSampleDynamicTick​

inline bool shouldSampleDynamicTick(
    uint64_t cycle,
    uint64_t last_sample
)

Start after a complete warm window, then leave a full window between accepted samples. The runtime additionally requires every cluster member to execute at the sampled cycle, so periodic and externally woken units cannot be measured through permanently idle phases.

function nextPeriodicCycle​

inline uint64_t nextPeriodicCycle(
    uint64_t cycle,
    uint64_t period
)

function isCanceled​

template <typename T >
inline bool isCanceled(
    const PortEnvelope< T > & msg
)

function dynamicWaitThreadYieldSpinMask​

uint64_t dynamicWaitThreadYieldSpinMask(
    bool lookahead_floor_wait
)

function dynamicClusterBurstEnd​

inline uint64_t dynamicClusterBurstEnd(
    uint64_t cycle,
    uint64_t end_cycle,
    uint64_t ready_through_cycle,
    uint64_t next_counter_cycle =UINT64_MAX
)

Bound a dynamic cluster's local burst by every externally visible scheduler frontier. The dependency proof is exclusive: a cluster proven ready through N may execute cycles [cycle, N).
