摘要： A method including accessing a work control structure (WCS) configured “first-in-first-out” holding work control records (WCRs) each including a field defining work to be carried out and a completion indicator indicating whether the work has completed, and initially set to indicate that the work has not completed: upon fetching a work request (WR) for execution, pushing a WCR corresponding to the WR to the WCS, and: A) inspecting the WCR at a head of the WCS, B) when the completion indicator of the WCR at the head of the WCS indicates that the unit of work associated with the WCR at the head of the WCS has been completed, popping the WCR at the head of the WCS from the WCS, and reporting completion of the WCR at the head of the WCS to a host processor, and C) iteratively performing A, B, and C. Related apparatus and methods are also provided.

摘要： A method for communication includes posting, by a software process, a set of buffers in a memory of a host processor and creating in the memory a list of labels associated respectively with the buffers. The software process pushes a first part of the list to a network interface controller (NIC), while retaining a second part of the list in the memory under control of the software process. Upon receiving a message containing a label, sent over a network, the NIC compares the label to the labels in the first part of the list and, upon finding a match to the label, writes data conveyed by the message to a buffer in the memory. Upon a failure to find the match in the first part of the list, the NIC passes the message from the NIC to the software process for handling using the second part of the list.

摘要： A peripheral device includes a bus interface and an Address Translation Service (ATS) controller. The bus interface is to communicate over a peripheral bus. The ATS controller is to communicate over the peripheral bus, including sending address translation requests and receiving address translations in response to the address translation requests, to cache at least some of the address translations in one or more Address Translation Caches (ATCs), to estimate one or more statistical properties of the received address translations, and to configure the one or more ATCs based on the one or more statistical properties.

摘要： A work descriptor identifying a plurality of workflow tasks to be performed by a hardware device is generated by a host system. A plurality of timestamp logging tasks are added to the work descriptor. Each of the plurality of timestamp logging tasks corresponds to one of the plurality of workflow tasks and instructs the hardware device to log a timestamp in response to an event associated with a respective workflow task. The work descriptor with the plurality of timestamp logging tasks is stored in a work queue of the host system. The work queue is accessible by the hardware device.

摘要： A network device in a communication network includes a controller and processing circuitry. The controller is configured to manage execution of an operation whose execution depends on inputs from a group of one or more work-request initiators. The processing circuitry is configured to read one or more values, which are set by the work-request initiators in one or more memory locations that are accessible to the work-request initiators and to the network device, and to trigger execution of the operation in response to verifying that the one or more values read from the one or more memory locations indicate that the work-request initiators in the group have provided the respective inputs.

摘要： A system includes a host processor, which has a host memory and is coupled to store data in a non-volatile memory in accordance with a storage protocol. A network interface controller (NIC) receives data packets conveyed over a packet communication network from peer computers containing, in payloads of the data packets, data records that encode data in accordance with the storage protocol for storage in the non-volatile memory. The NIC processes the data records in the data packets that are received in order in each flow from a peer computer and extracts and writes the data to the host memory, and when a data packet arrives out of order, writes the data packet to the host memory without extracting the data and processes the data packets in the flow so as to recover context information for use in processing the data records in subsequent data packets in the flow.
