Abstract

A method and apparatus for performing operations by network interface cards in a network of computers. A network interface card is configured to receive a message and to interpret the message to identify a primitive operation to be performed. The primitive operation is one of a plurality of primitive operations that are performed to perform an operation. The primitive operation is performed by the network interface card and a trigger signal is generated in response to performing the primitive operation. The trigger signal is interpreted to identify a triggered message. The triggered message identifies a next one of the plurality of primitive operations to be performed. The triggered message is transmitted back to the network interface card or to another network interface card in the network for processing.

Dependent claims

A method of performing an operation by a network interface card for a host computer that connects the host computer to a network, the method comprising:

receiving a message;
interpreting the message to identify a primitive operation to be performed, wherein the primitive operation is one of a plurality of primitive operations that are performed to perform the operation;
performing the primitive operation;
generating a trigger signal in response to performing the primitive operation;
interpreting the trigger signal to identify a triggered message, wherein the triggered message identifies a next one of the plurality of primitive operations to be performed;
transmitting the triggered message back to the network interface card for the host computer or to another network interface card for another computer on the network, and further comprising:
receiving the triggered message by the network interface card or the other network interface card;
interpreting the triggered message, by the network interface card or the other network interface card, to identify another primitive operation to be performed, wherein the other primitive operation is another one of the plurality of primitive operations that are performed to perform the operation;
performing the other primitive operation by the network interface card or the other network interface card;
generating another trigger signal, by the network interface card or the other network interface card, in response to performing the other primitive operation;
interpreting the other trigger signal, by the network interface card or the other network interface card, to identify another triggered message, wherein the other triggered message identifies a further next one of the plurality of primitive operations to be performed;
and
transmitting the other triggered message by the network interface card or the other network interface card.

A method of performing an operation by a network interface card for a host computer that connects the host computer to a network, the method comprising:

receiving a message comprising a message tag;
using the message tag to identify an entry in a match table, wherein the entry in the match table identifies a primitive operation to be performed, wherein the primitive operation is one of a plurality of primitive operations that are performed to perform the operation;
performing the primitive operation;
changing a value of a counter in response to performing the primitive operation;
using the value of the counter to identify a triggered message, wherein the triggered message comprises a triggered message tag identifying a next one of the plurality of primitive operations to be performed;
transmitting the triggered message back to the network interface card for the host computer, and further comprising:
receiving the triggered message by the network interface card;
using the triggered message tag to identify another entry in the match table, wherein the other entry in the match table identifies another primitive operation to be performed, wherein the other primitive operation is another one of the plurality of primitive operations that are performed to perform the operation;
performing the other primitive operation by the network interface card;
changing the value of the counter in response to performing the other primitive operation;
using the value of the counter to identify another triggered message, wherein the other triggered message comprises another triggered message tag identifying a next one of the plurality of primitive operations to be performed;
and
transmitting the other triggered message.
