摘要： Data communications may be carried out in a distributed computing environment that includes a plurality of computers coupled for data communications through communications adapters and an active messaging interface (‘AMI’). In distributed computing environment, data communications may include: receiving in the AMI from an application an eager SEND instruction that describes the location and size of send data in an application SEND buffer; copying by the AMI the send data from the application SEND buffer to a temporary AMI buffer; advising the application of completion of the SEND instruction before sending the SEND data to the receiver; and after advising the application of completion of the SEND instruction, sending the SEND data by the sender to the receiver.

Each compute node including an operating system kernel and a system-level messaging module that is a module of automated computing machinery that exposes a messaging interface to applications. Each compute node including a routing table that specifies, for each of a multiplicity of route identifiers, a data communications path through the compute node. Including to carry out the steps of: receiving in a compute node a data communications packet that includes a route identifier value; retrieving from the routing table a specification of a data communications path through the compute node; and routing, by the compute node, the data communications packet according to the data communications path identified by the compute node's routing table entry for the data communications packet's route identifier value.

摘要： Data communications may be carried out in a distributed computing environment that includes a plurality of computers coupled for data communications through communications adapters and an active messaging interface (‘AMI’). In such an environment, data communications may include: issuing, by a sender to a receiver, an eager SEND data communications instruction to transfer SEND data, the instruction including information describing a location and size of a send buffer in which the SEND data is stored; transmitting, by the sender to the receiver, the SEND data as eager data packets; issuing, by the receiver to the sender in dependence upon data flow conditions, a STOP instruction, the STOP instruction including an order to stop transmitting the eager data packets; and transferring the SEND data by the receiver from the sender's data location to a receive buffer by remote direct memory access (“RDMA”).

摘要： Collective operation protocol selection in a parallel computer that includes compute nodes may be carried out by calling a collective operation with operating parameters; selecting a protocol for executing the operation and executing the operation with the selected protocol. Selecting a protocol includes: iteratively, until a prospective protocol meets predetermined performance criteria: providing, to a protocol performance function for the prospective protocol, the operating parameters; determining whether the prospective protocol meets predefined performance criteria by evaluating a predefined performance fit equation, calculating a measure of performance of the protocol for the operating parameters; determining that the prospective protocol meets predetermined performance criteria and selecting the protocol for executing the operation only if the calculated measure of performance is greater than a predefined minimum performance threshold.
