Abstract: Examples described herein relates to a network interface apparatus that includes packet processing circuitry and a bus interface. In some examples, the packet processing circuitry to: process a received packet that includes data, a request to perform a write operation to write the data to a cache, and an indicator that the data is to be durable and based at least on the received packet including the request and the indicator, cause the data to be written to the cache and non-volatile memory. In some examples, the packet processing circuitry is to issue a command to an input output (IO) controller to cause the IO controller to write the data to the cache and the non-volatile memory. In some examples, the cache comprises one or more of: a level-0 (L0), level-1 (L1), level-2 (L2), or last level cache (LLC) and the non-volatile memory comprises one or more of: volatile memory that is part of an Asynchronous DRAM Refresh (ADR) domain, persistent memory, battery-backed memory, or memory device whose state is determinate even if power is interrupted to the memory device. In some examples, based on receipt of a second received packet that includes a request to persist data, the packet processing circuitry is to request that data stored in a memory buffer be copied to the non-volatile memory.

Abstract: Examples may include a method of compiling a declarative language program for a virtual switch. The method includes parsing the declarative language program, the program defining a plurality of match-action tables (MATs), translating the plurality of MATs into intermediate code, and parsing a core identifier (ID) assigned to each one of the plurality of MATs. When the core IDs of the plurality of MATs are the same, the method includes connecting intermediate code of the plurality of MATs using function calls, and translating the intermediate code of the plurality of MATs into machine code to be executed by a core identified by the core IDs.

Abstract: Method and system for performing data movement operations is described herein. One embodiment of a method includes: storing data for a first memory address in a cache line of a memory of a first processing unit, the cache line associated with a coherency state indicating that the memory has sole ownership of the cache line; decoding an instruction for execution by a second processing unit, the instruction comprising a source data operand specifying the first memory address and a destination operand specifying a memory location in the second processing unit; and responsive to executing the decoded instruction, copying data from the cache line of the memory of the first processing unit as identified by the first memory address, to the memory location of the second processing unit, wherein responsive to the copy, the cache line is to remain in the memory and the coherency state is to remain unchanged.

Abstract: Apparatus, methods, and systems for tuple space search-based flow classification using cuckoo hash tables and unmasked packet headers are described herein. A device can communicate with one or more hardware switches. The device can include memory to store hash table entries of a hash table. The device can include processing circuitry to perform a hash lookup in the hash table. The lookup can be based on an unmasked key include in a packet header corresponding to a received data packet. The processing circuitry can retrieve an index pointing to a sub-table, the sub-table including a set of rules for handling the data packet. Other embodiments are also described.

Abstract: Technologies for enforcing coherence ordering in consumer polling interactions include a network interface controller (NIC) of a target computing device which is configured to receive a network packet, write the payload of the network packet to a data storage device of the target computing device, and obtain, subsequent to having transmitted a last write request to write the payload to the data storage device, ownership of a flag cache line of a cache of the target computing device. The NIC is additionally configured to receive a snoop request from a processor of the target computing device, identify whether the received snoop request corresponds to a read flag snoop request associated with an active request being processed by the NIC, and hold the received snoop request for delayed return in response to having identified the received snoop request as the read flag snoop request. Other embodiments are described herein.

Abstract: Apparatus and methods implementing a hardware queue management device for reducing inter-core data transfer overhead by offloading request management and data coherency tasks from the CPU cores. The apparatus include multi-core processors, a shared L3 or last-level cache (“LLC”), and a hardware queue management device to receive, store, and process inter-core data transfer requests. The hardware queue management device further comprises a resource management system to control the rate in which the cores may submit requests to reduce core stalls and dropped requests. Additionally, software instructions are introduced to optimize communication between the cores and the queue management device.

Abstract: Technologies for providing information to a user while traveling include a mobile computing device to determine network condition information associated with a route segment. The route segment may be one of a number of route segments defining at least one route from a starting location to a destination. The mobile computing device may determine a route from the starting location to the destination based on the network condition information. The mobile computing device may upload the network condition information to a crowdsourcing server. A mobile computing device may predict a future location of the device based on device context, determine a safety level for the predicted location, and notify the user if the safety level is below a threshold safety level. The device context may include location, time of day, and other data. The safety level may be determined based on predefined crime data.
