Edge DPU runtime N2Cube support DPU core affinity with the API dpuSetTaskAffinity(), which can be used to dynamically assign DPU tasks to desired DPU cores so that the users can participate in DPU cores' assignment and scheduling as required. DPU cores’ affinity is specified with the second argument coreMask to dpuSetTaskAffinity(). Each bit of coreMask represents one DPU core: the lowest bit is for core 0, second lowest bit is for core 1, and so on. Multiple mask bits can be specified one time but can’t exceed the maximum available DPU cores. For example, the mask value 0x3 indicates that a task can be assigned to DPU core 0 and 1, and it is scheduled right away if either core 0 or 1 is available.
