Abstract
Embodiments relate to the orchestration of data shuffling among memory devices of a non-uniform memory access device. An aspect includes a method of orchestrated shuffling of data in a non-uniform memory access device includes running an application on a plurality of threads executing on a plurality of processing nodes and identifying data to be shuffled among the plurality of processing nodes. The method includes registering the data to be shuffled and generating a plan for orchestrating the shuffling of the data. The method further includes disabling cache coherency of cache memory associated with the processing nodes and shuffling the data among all of the memory devices upon disabling the cache coherency, the shuffling performed based on the plan for orchestrating the shuffling. The method further includes restoring the cache coherency of the cache memory based on completing the shuffling of the data among all of the memory devices.
