The 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 you can participate in DPU core assignment
and scheduling, as required. DPU core 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 cannot 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.
