return results_processed;

The collect result function simply iterates over all devices and each stream of every device and calls the process_result function to try to process any available results.

__host__ bool process_result(const u32 device_num,

const u32 stream_num,

const size_t chunk_size)

{

bool result;

bool stop_event_hit = (cudaEventQuery(memcpy_from_stop_event[device_num][stream_num]) == cudaSuccess);

// Space is avaiable if network_out_idx is not

// more than the total queue length behind

bool output_space_avail = ((completed_idx - network_out_idx) < MAX_OUT_QUEUED_PACKETS);
