Using send buffers and receive buffers for sending messages among nodes in a network

A system for transmitting messages among nodes in a network, comprising:

• at least one processor;
• and
• a computer readable storage medium having computer program code executed by the processor to perform operations as a sending node to send message in the network to other nodes comprising receiving nodes, the operations comprising:
• providing a send buffer for each of at least one receiving node comprising one of the nodes to which messages are sent, wherein each of the at least one receiving node includes at least one receive buffer to receive messages from the send buffer at the sending node, wherein the send and receive buffers for a message being sent from the sending node to one of the at least one receiving node have corresponding entries;
• requesting from a buffer manager a buffer entry for a send buffer and a receive buffer pair for a message, wherein the send buffer is in the sending node and the receive buffer is in a receiving node;
• indicating in the message, to send to the receiving node, the buffer entry for the send buffer and the receive buffer pair;
• and
• sending, from the send buffer of the sending node, the message to the receiving node indicating the buffer entry to cause the receiving node to include the message in the indicated buffer entry in the receive buffer the receiving node maintains for the node from which the message is sent.
