The receiving computing device is further configured to compare the descriptors to determine whether the descriptors match. Upon finding a match, the receiving computing device is still further configured to perform an operation corresponding to the inspection entries whose descriptor matches the descriptor of the message.

Abstract: 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.

Abstract: This disclosure is directed to a system for event dissemination. In general, a system may comprise a plurality of devices each including an event dissemination module (EDM) configured to disseminate events between the plurality of devices. New events may be generated during the normal course of operation in each of the plurality of devices. These events may be provided to at least one device designated as a network dispatch location. The network dispatch location may initiate the dissemination of the events. For example, each device may place received events into a local event queue within the device. The placement of an event into the local event queue may cause a counter in the EDM to increment. Incrementing the counter may, in turn, cause a trigger operation module in the EDM to perform at least one activity including, for example, forwarding the event to other devices within the plurality of devices.

Abstract: Technologies for one-side remote memory access communication include multiple computing nodes in communication over a network. A receiver computing node receives a message from a sender node and extracts a segment identifier from the message. The receiver computing node determines, based on the segment identifier, a segment start address associated with a partitioned global address space (PGAS) segment of its local memory. The receiver computing node may index a segment table stored in the local memory or in a host fabric interface. The receiver computing node determines a local destination address within the PGAS segment based on the segment start address and an offset included in the message. The receiver computing node performs a remote memory access operation at the local destination address. The receiver computing node may perform those operations in hardware by the host fabric interface of the receiver computing node. Other embodiments are described and claimed.

Abstract: Systems, apparatuses and methods may provide for detecting an outbound communication and identifying a context of the outbound communication. Additionally, a completion status of the outbound communication may be tracked relative to the context. In one example, tracking the completion status includes incrementing a sent messages counter associated with the context in response to the outbound communication, detecting an acknowledgement of the outbound communication based on a network response to the outbound communication, incrementing a received acknowledgements counter associated with the context in response to the acknowledgement, comparing the sent messages counter to the received acknowledgements counter, and triggering a per-context memory ordering operation if the sent messages counter and the received acknowledgements counter have matching values.

The transceiver module may further be configured to write the data portion to the memory buffer at the destination address; and the offset handler module may further be configured to update the offset counter based on the data size indicator.
