Publication number: 20220011966Abstract: Methods and apparatus for reduced network load with receiver-managed offset (RMO) PUT or GET messages. An RMO PUT message including an RMO key, data, and a length is sent from an initiator to a target, where the RMO key is extracted by a Network Interface controller (NIC), SmartNIC, or Infrastructure Processing Unit and used to identify an address or address offset of a memory buffer in a target memory at which to write the data. An RMO GET message is sent from an initiator to a target and includes an RMO key, a source buffer on the target, and a length. The target processes the RMO GET, reads the length of data from its source buffer, and returns a message to the initiator including the RMO key, the read data, and the length. The RMO key is extracted and used to identify an address or address offset of a memory buffer in a memory on the initiator in which to write the read data.Type: ApplicationFiled: September 24, 2021Publication date: January 13, 2022Inventors: David KEPPEL, David M.

Publication number: 20200233814Abstract: Examples described herein relate to a computing system supporting custom page sized ranges for an application to map contiguous memory regions instead of many smaller sized pages. An application can request a custom range size. An operating system can allocate a contiguous physical memory region to a virtual address range by specifying a custom range sizes that are larger or smaller than the normal general page sizes. Virtual-to-physical address translation can occur using an address range circuitry and translation lookaside buffer in parallel. The address range circuitry can determine if a custom entry is available to use to identify a physical address translation for the virtual address. Physical address translation can be performed by transforming the virtual address in some examples.Type: ApplicationFiled: February 10, 2020Publication date: July 23, 2020Inventors: Farah E. FARGO, Mitchell DIAMOND, David KEPPEL, Samantika S. SURY, Binh PHAM, Shobha VISSAPRAGADA

Patent number: 10178041Abstract: Technologies for aggregation-based message processing include multiple computing nodes in communication over a network. A computing node receives a message from a remote computing node, increments an event counter in response to receiving the message, determines whether an event trigger is satisfied in response to incrementing the counter, and writes a completion event to an event queue if the event trigger is satisfied. An application of the computing node monitors the event queue for the completion event. The application may be executed by a processor core of the computing node, and the other operations may be performed by a host fabric interface of the computing node. The computing node may be a target node and count one-sided messages received from an initiator node, or the computing node may be an initiator node and count acknowledgement messages received from a target node. Other embodiments are described and claimed.Type: GrantFiled: September 23, 2015Date of Patent: January 8, 2019Assignee: Intel CorporationInventors: James Dinan, Mario Flajslik, David Keppel, Ulf R.
