WebDescription of basic methods: ConcurrentQueue(size_t initialSizeEstimate) Constructor which optionally accepts an estimate of the number of elements the queue will hold enqueue(T&& item) Enqueues one item, allocating extra space if necessary try_enqueue(T&& item) Enqueues one item, but only if enough memory is already … WebJun 4, 2024 · TBB Concurrent Hash map. 10,499. You HashCompare::hash () returns sizeof (int), which, I guess, means every entry maps into the same bucket. It seems like you are not using it as a hash table, more of a linked list. You could try using Boost's hash:
