TECHNIQUE FOR REDUCING THE OVERHEAD OF PROVIDING RESPONSES IN A COMPUTING NETWORK

The invention provides a technique for reducing the overhead of providing responses in a computing network. An endpoint in a network may make posted or non-posted write requests to another endpoint inthe network. For a non-posted write request, the target endpoint provides a response to the requesting endpoint indicating that the write request has been serviced. For a posted write request, the target endpoint does not provide such an acknowledgment. Hence, posted write requests have lower overhead, but they suffer from potential synchronization and resiliency issues. While non-posted write requests do not have those issues, they cause increased load on the network because such requests require the target endpoint to acknowledge each write request. Introduced herein is a network operationtechnique that uses non-posted transactions while maintaining a load overhead of the network as a manageable level. The introduced technique reduces the load overhead of the non-posted write requestsby collapsing and reducing
