Abstract: Communication over a computer network with a node having a first port with a point-to-point link connection to a second node having a second port. The first port transmits to the second port a reliable link layer (RLL) packet over the link. The RLL packet comprises a first RLL header and a first data packet, the first RLL header preceding the first data packet, the first RLL header comprising an RLL start-of-frame (SOF) character and an RLL packet sequence number (PSN). If the first port receives an RLL acknowledgment control packet from the link, it acknowledges receipt of the first data packet, and the first port does not retain the first data packet in the buffer. If the first port does not receive the RLL acknowledgment packet from the link, acknowledging receipt of the first data packet, the first port re-transmits from the buffer the first data packet.

Abstract translation: 通过计算机网络与具有具有到具有第二端口的第二节点的点对点链路连接的第一端口的节点进行通信。 第一端口通过链路向第二端口传送可靠的链路层（RLL）分组。 RLL分组包括第一RLL头部和第一数据分组，在第一数据分组之前的第一RLL头部，第一RLL头部包括RLL开始帧（SOF）字符和RLL分组序列号（PSN）。 如果第一端口从链路接收到RLL确认控制分组，则它确认接收到第一数据分组，并且第一端口不保留缓冲器中的第一数据分组。 如果第一端口没有从链路接收到RLL确认分组，则确认接收到第一数据分组，则第一端口从缓冲器重新发送第一数据分组。

Abstract: A system for a message processing system in which messages are transmitted from source nodes to destination nodes. A transmission flow control technique is disclosed in which the source node optimistically sends control information and a data portion of a message, and wherein a destination node discards the data portion of the message if it is unable to accommodate it. The destination node, however, retains enough of the control information to identify the message to the source node, and when the destination node is subsequently able to accommodate the data portion, the destination node issues a request to the source node to retransmit the data portion of the message. Discarding of one message is followed by discards of sequential messages, until the destination node is able to accommodate the data portions of messages. The flow control technique disclosed herein is used, for example, in an environment where buffers are posted to accommodate messages at the destination node, and is particularly suited for conditions arising in multi-tasking systems where the destination node is generally assumed to be prepared to accommodate data, however, if not prepared, is likely not prepared for long periods of time.

Abstract: A message-passing protocol for accommodating early arrival messages passed between source and destination nodes in a computer system with a plurality of asynchronous computing nodes interconnected by bidirectional asynchronous communications channels. The protocol includes transmitting the message from sender to receiver without waiting for a request for the message from the receiver; determining at the receiver if a receive buffer has been posted for the message; and if the receive buffer has not been posted for the message, then either truncating the message by storing its message header in an early arrival queue at the receiver and discarding its data or allocating a temporary receive buffer at the receiver to hold the message data. Upon the receiver being ready to post a receive buffer for an early arrival message, the receiver checks the early arrival queue for the corresponding message header, and if the message header is in the early arrival queue and the message data has been discarded, then the receiver sends a pull request to the sender to retransmit the message to the receiver.

Abstract translation: 一种消息传递协议，用于容纳在具有通过双向异步通信信道互连的多个异步计算节点的计算机系统中的源节点与目的节点之间传递的早到信息。 该协议包括从发送方发送消息到接收方，而不等待来自接收方的消息请求; 在接收器处确定是否已经为消息发布接收缓冲器; 并且如果接收缓冲器尚未被发送给消息，则通过将消息头部存储在接收器的早期到达队列中并且丢弃其数据或者在接收器处分配临时接收缓冲器来保存消息数据来截断该消息。 在接收器准备好发送用于早期到达消息的接收缓冲器的情况下，接收机检查相应消息报头的早期到达队列，并且如果消息报头处于早期到达队列中并且消息数据已被丢弃，则 接收方向发送方发送拉取请求，以将消息重发到接收方。

Abstract: A system and method for providing a memory region/memory window (MR/MW) access notification on a system area network are provided. Whenever a previously allocated MR/MW is accessed, such as via a remote direct memory access (RDMA) read/write operation, a notification of the access is generated and written to a queue data structure associated with the MR/MW. In one illustrative embodiment, this queue data structure may be a MR/MW event queue (EQ) data structure that is created and used for all consumer processes and all MR/MWs. In other illustrative embodiments, the EQ is associated with a protection domain. In yet another illustrative embodiment, an event record may be posted to an asynchronous event handler in response to the accessing of the MR/MW. In another illustrative embodiment, a previously posted queue element may be used to generate a completion queue element in response to the accessing of the MR/MW.

Abstract: A system and method for collective send operations on a system area network are provided. The mechanisms of the illustrative embodiments provide for the creation, modification, and removal of collective send queues (CSQs) that allow the upper level protocol (ULP) used by a consumer to send the same message to a collective set of queue pairs (QPs). In order to use the transport services of a CSQ, a consumer process posts a write work request (WR) to the CSQ. The write WR causes a write work queue element (WQE) to be generated and placed in the CSQ. A channel interface (CI) is provided that effectively copies the write WQE to all of the send queues (SQs) of the QPs in the QP set associated with the CSQ. When all the QPs complete processing of their respective write WQEs, the HCA releases all data segments referenced by the write WR.
