Abstract: Lock access is managed in a data network having an initiator node and a remote target by issuing a lock command from a first process to the remote target via an initiator network interface controller to establish a lock on a memory location, and prior to receiving a reply to the lock command communicating a data access request to the memory location from the initiator network interface controller. Prior to receiving a reply to the data access request, an unlock command issues from the initiator network interface controller. The target network interface controller determines the lock content, and when permitted by the lock accesses the memory location. After accessing the memory location the target network interface controller executes the unlock command. When the lock prevents data access, the lock operation is retried a configurable number of times until data access is allowed or a threshold is exceeded.

Abstract: A data processing device includes a first packet communication interface for communication with at least one host processor via a network interface controller (NIC) and a second packet communication interface for communication with a packet data network. A memory holds a flow state table containing context information with respect to multiple packet flows conveyed between the host processor and the network via the first and second interfaces packet communication interfaces. Acceleration logic, coupled between the first and second packet communication interfaces, performs computational operations on payloads of packets in the multiple packet flows using the context information in the flow state table.

Abstract: A data storage system includes a storage server, including non-volatile memory (NVM) and a server network interface controller (NIC), which couples the storage server to a network. A host computer includes a host central processing unit (CPU), a host memory and a host NIC, which couples the host computer to the network. The host computer runs a driver program that is configured to receive, from processes running on the host computer, commands in accordance with a protocol defined for accessing local storage devices connected to a peripheral component interface bus of the host computer, and upon receiving a storage access command in accordance with the protocol, to initiate a remote direct memory access (RDMA) operation to be performed by the host and server NICs so as to execute on the storage server, via the network, a storage transaction specified by the command.

Abstract: A method for network access of remote memory directly from a local instruction stream using conventional loads and stores. In cases where network IO access (a network phase) cannot overlap a compute phase, a direct network access from the instruction stream greatly decreases latency in CPU processing. The network is treated as yet another memory that can be directly read from, or written to, by the CPU. Network access can be done directly from the instruction stream using regular loads and stores. Example scenarios where synchronous network access can be beneficial are SHMEM (symmetric hierarchical memory access) usages (where the program directly reads/writes remote memory), and scenarios where part of system memory (for example DDR) can reside over a network and made accessible by demand to different CPUs.
