Abstract: A smart NIC (Network Interface Card) is provided with features to enable the smart NIC to operate as an in-line NIC between a host's NIC and a network. The smart NIC provides pass-through transmission of network flows for the host. Packets sent to and from the host pass through the smart NIC. As a pass-through point, the smart NIC is able to accelerate the performance of the pass-through network flows by analyzing packets, inserting packets, dropping packets, inserting or recognizing congestion information, and so forth. In addition, the smart NIC provides a lightweight transport protocol (LTP) module that enables it to establish connections with other smart NICs. The LTP connections allow the smart NICs to exchange data without passing network traffic through their respective hosts.

Abstract: A method including fetching a group of instructions, where the group of instructions is configured to execute atomically by a processor, is provided. The method further includes scheduling at least one of the group of instructions for execution by the processor before decoding the at least one of the group of instructions based at least on pre-computed ready state information associated with the at least one of the group of instructions.

Abstract: A method including fetching a group of instructions, where the group of instructions is configured to execute atomically by a processor is provided. The method further includes decoding at least one of a first instruction or a second instruction, where: (1) decoding the first instruction results in a processing of information about a group of instructions, including information about a size of the group of instructions, and (2) decoding the second instruction results in a processing of at least one of: (a) a reference to a memory location having the information about the group of instructions, including information about the size of the group of instructions or (b) a processor status word having information about the group of instructions, including information about the size of the group of instructions.

Abstract: A method including fetching a group of instructions, including a group header for the group of instructions, where the group of instructions is configured to execute by a processor, and where the group header includes a field including locking information for at least one operand is provided. The method further includes storing a value of the at least one operand in at least one operand buffer of the processor and based on the locking information, locking a value of the at least one operand in the at least one operand of the buffer such that the at least one operand is not cleared from the at least one operand buffer of the processor in response to completing the execution of the group of instructions.
