Congestion management techniques for communication networks are described. In an example embodiment, an apparatus may comprise circuitry, a communication component for execution by the circuitry to receive a send request identifying a message to be received from an initiator device via a packet transfer process and transmit an acceptance to grant the send request, and a scheduling component for execution by the circuitry to determine whether to defer the packet transfer process and in response to a determination to defer the packet transfer process, select a value of a delay parameter to be included in the acceptance. Other embodiments are described and claimed.

Congestion management techniques for communication networks

Techniques are disclosed for algorithmic mapping of logical process identifiers in order to provide highly-scalable end-point addressing in multi-node systems capable of performing massively parallel applications. In particular, nodes initiating inter-process communication with a target process may use an initiator-side translation process that performs an algorithmic mapping to translate a logical process identifier (e.g., a rank/processing element) into a target physical node identifier and a target local process identifier. The initiating node may then use hardware fabric of a multi-node network to route the inter-process communication to an appropriate node. A node may receive an inter-process communication and may use a target-side translation process in hardware to translate the target virtual process identifier into a local process identifier for the node. The node may then execute an operation in accordance with the inter-process communication, such as a get or set against a memory associated with the node.
