calculateImplicitMap()

static AffineMap calculateImplicitMap ( VectorType  sequentialType, VectorType  distributedType  )

static

Currently the distribution map is implicit based on the vector shape.

In the future it will be part of the op. Example:

%0 = gpu.warp_execute_on_lane_0(%arg0) -> (vector<1x16x2xf32>) {
  ...
  gpu.yield %3 : vector<32x16x64xf32>
}

Would have an implicit map of: (d0, d1, d2) -> (d0, d2)
