Abstract
Techniques for tracking completion of transfer requests. In one embodiment, a compute node connects to a network adapter (NA). In one embodiment, software running on the compute node contains instructions in which some remote data transfer requests belong to (or are associated with) completion groups. These completion groups may be constructed so that the system may more efficiently determine the completion status of remote transfer requests. In one embodiment, The NA includes a hardware counter for each completion group (CG). In one embodiment, the counter is configured to count when each transfer request in the completion group is received and when each request in the completion group is completed. For example, the counter may increment on receipt and decrement on completion such that a zero indicates completion of all requests in the completion group. In one embodiment, the NA includes a flush register to indicate whether the counter is valid.
