Completion tracking for groups of transfer requests

A method, comprising:

• receiving, via a local interface, a plurality of transfer requests from a local compute node, wherein requests of the plurality of transfer requests are associated with a completion group;
• counting, using counter circuitry, when each transfer request associated with the completion group is received;
• transmitting, on a network interface, the plurality of transfer requests;
• counting, using the counter circuitry, when each transmitted transfer request is completed;
• indicating, based on reception of an ordering command from the local compute node, whether a current count of the counter circuitry is valid, wherein the ordering command forces outstanding transfer requests from the local compute node to the network interface ahead of the ordering command;
• and
• determining, based on the counting the reception and completion of the plurality of transfer requests and the indication, completion status of the completion group.

A system, comprising:

• a network adapter comprising:
• a local interface;
• a network interface;
• and
• first counter circuitry;
• wherein the network adapter is configured to:
• receive, via the local interface, a plurality of transfer requests associated with a first completion group;
• count, using the first counter circuitry, a number of received transfer requests associated with the first completion group;
• and
• count, using the first counter circuitry, a number of completed transfer requests associated with the first completion group
• indicate, using a flush indicator based on reception of an ordering command from the local interface, whether a current count of the counter circuitry is valid, wherein the ordering command forces outstanding transfer requests from a local compute node to the network interface ahead of the ordering command.
