Atomic operations

摘要

The disclosed embodiments relate to a communication device for use in a node of a system having a plurality of nodes. Each of the plurality of nodes may include network interface controllers ("NICs") and each of the NICs may have an atomic operation logic device therewith. The atomic operation logic may receive from a requester a packet that contains a request to perform an atomic operation. Then the atomic operation logic may determine that the atomic operation is being requested from the information within the packet. The atomic operation logic may also respond to the requester to indicate whether the atomic operation has been performed.
