I am confused here, it seems to me this is not an error of the plan. The iteration set is defined as ```elem = op2.Set(2)``` which translate to ```elem = op2.Set([2,2,2,2])``` (see base.py::class Set) shoudn't it be defined as ```elem = op2.Set([0,2,2,2])``` ? in which case the plan is:
```
PPlan
nblocks: 1
nelems: [2]
offset: [0]
ncolors / core / owned: 1 / 0 / 0
pcolors: [0]
blkmap: [0]
ncolblk: [1]
```
