Abstract: Technologies for improving throughput in a network include a node switch. The node switch is to obtain expected performance data indicative of an expected data transfer performance of the node switch. The node switch is also to obtain measured performance data indicative of a measured data transfer performance of the node switch, compare the measured performance data to the expected performance data to determine whether the measured data transfer performance satisfies the expected data transfer performance, determine, as a function of whether the measured data transfer performance satisfies the expected data transfer performance, whether to force a unit of data through a non-minimal path to a destination, and send, in response to a determination to force the unit of data to be sent through a non-minimal path, the unit of data to an output port of the node switch associated with the non-minimal path. Other embodiments are also described.

Abstract: Technologies for extending triggered operations include a host fabric interface (HFI) of a compute device configured to detect a triggering event associated with a counter, increment the counter, and determine whether a value of the counter matches a trigger threshold of a triggered operation in a triggered operation queue associated with the counter. The HFI is further configured to execute, one or more commands associated with the triggered operation upon determining that the value of the counter matches the trigger threshold, and determine, subsequent to the execution of the one or more commands, whether the triggered operation corresponds to a recurring triggered operation. The HFI is additionally configured to increment, in response to a determination that the triggered operation corresponds to a recurring triggered operation, the value of the trigger threshold by a threshold increment and re-insert the triggered operation into the triggered operation queue. Other embodiments are described herein.

Abstract: Technologies for synchronizing triggered operations include a host fabric interface (HFI) of a compute device configured to receive an operation execution command associated with a triggered operation that has been fired and determine whether the operation execution command includes an instruction to update a table entry of a table managed by the HFI. Additionally, the HFI is configured to issue, in response to a determination that the operation execution command includes the instruction to update the table entry, a triggered list enable (TLE) operation and a triggered list disable (TLD) operation to a table manager of the HFI and disable a corresponding table entry in response to the TLD operation having been triggered, the identified table entry. The HFI is further configured to execute one or more command operations associated with the received operation execution command and re-enable, in response to the TLE operation having been triggered, the table entry. Other embodiments are described herein.

Abstract: Technologies for generating triggered conditional events operations include a host fabric interface (HFI) of a compute device configured to receive an operation execution command message associated with a triggered operation that has been fired, process the received operation execution command message to extract and store argument information from the received operation execution command, and increment an event counter associated with the fired triggered operation. The HFI is further configured to perform a triggered compare-and-generate event (TCAGE) operation as a function of the extracted argument information, determine whether to generate a triggering event, generate the triggering event as a function of the performed TCAGE operation, insert the generated triggered event into a triggered operation queue, and update the value of the event counter. Other embodiments are described herein.

Abstract: Technologies for managing a queue on a compute device are disclosed. In the illustrative embodiment, the queue is managed by a host fabric interface of the compute device. Queue operations such as enqueuing data onto the queue and dequeuing data from the queue may be requested by remote compute devices by sending queue operations which may be processed by the host fabric interface. The host fabric interface may, in some embodiments, fully manage the queue without any assistance from the processor of the compute device. In other embodiments, the processor of the compute device may be responsible for certain tasks, such as garbage collection.

Abstract: Techniques are disclosed to throttle bandwidth imbalanced data transfers. In some examples, an example computer-implemented method may include splitting a payload of a data transfer operation over a network fabric into multiple chunk get operations, starting the execution of a threshold number of the chunk get operations, and scheduling the remaining chunk get operations for subsequent execution. The method may also include executing a scheduled chunk get operation in response determining a completion of an executing chunk get operation. In some embodiments, the chunk get operations may be implemented as triggered operations.
