Examples include a computing system having a direct memory access (DMA) engine pipeline, a plurality of processing cores, each processing core including a core pipeline, and a memory coupled to the DMA engine pipeline and the plurality of processing cores. The computing system includes a pipeline selector coupled to the plurality of processing cores and the DMA engine pipeline, the pipeline selector to, during initialization, determine at least one threshold for pipeline selection for the computing system, and during runtime, select one of the core pipelines or the DMA engine pipeline to execute a memory copy operation in the memory based at least in part on the at least one threshold.

Adaptive pipeline selection for accelerating memory copy operations

Technologies for managing a single-producer and single-consumer ring include a producer of a compute node that is configured to allocate data buffers, produce work, and indicate that work has been produced. The compute node is configured to insert reference information for each of the allocated data buffers into respective elements of the ring and store the produced work into the data buffers. The compute node includes a consumer configured to request the produced work from the ring. The compute node is further configured to dequeue the reference information from each of the elements of the ring that correspond to the portion of data buffers in which the produced work has been stored, and set each of the elements of the ring for which the reference information has been dequeued to an empty (i.e., NULL) value. Other embodiments are described herein.
