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.
