CROSS-CHANNEL NETWORK OPERATION OFFLOADING FOR COLLECTIVE OPERATIONS
First Claim
1. A Network Interface (NI), comprising:
- a host interface, which is configured to receive from a host processor of a node one or more cross-channel work requests that are derived from an operation to be executed by the node;
a plurality of work queues for carrying out transport channels to one or more peer nodes over a network; and
control circuitry, which is configured to accept the cross-channel work requests via the host interface, and to execute the cross-channel work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.

Abstract
A Network Interface (NI) includes a host interface, which is configured to receive from a host processor of a node one or more cross-channel work requests that are derived from an operation to be executed by the node. The NI includes a plurality of work queues for carrying out transport channels to one or more peer nodes over a network. The NI further includes control circuitry, which is configured to accept the cross-channel work requests via the host interface, and to execute the cross-channel work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.

-
in a Network Interface (NI) that includes a plurality of work queues for carrying out transport channels to one or more peer nodes over a network, receiving from a host processor of a node one or more cross-channel work requests that are derived from an operation to be executed by the node; and executing the cross-channel work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A computer software product, comprising a computer-readable storage medium in which program instructions are stored, which instructions, when read by a computer, cause the computer to receive from a host processor of a node one or more cross-channel work requests that are derived from an operation to be executed by the node, and to execute the cross-channel work requests using a plurality of work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.
