进入到这个实现类中,我们可以看到,它主要是通过java AQS和ArrayDeque双端队列来实现的: 在这个队列中,每一个元素被包装成StreamElementQueueEntry,它实际上是Promise的抽象实现(参考Scala的Promise)在这个Entry类中,它会注册回调函数并且判断是否完成然后将消息发送给下游处理: 到这里,我们大概了解到了其基本的工作的原理...
QueuePair发送队列 通过读取ms_async_rdma_receive_buffer与ms_async_rdma_send_buffers来配置注册内存大小,在Device::create_queue_pair()中,会根据ms_async_rdma_send_buffers来创建QueuePair.,即 Infiniband::QueuePair*Device::create_queue_pair(IcfsContext *cct, ibv_qp_type type){ Infiniband::QueuePair *...
