It seems the partitioning of the input dataset is broken. When nprocs > 2 I get this error from pmesh

File "/Users/nhand/Research/Programs/nbodykit/bin/nbkit.py", line 164, in main
result = alg.run()
File "/Users/nhand/Research/Programs/nbodykit/nbodykit/core/algorithms/PaintGrid.py", line 82, in run
real2.unsort(ds[start:end])
File "/Users/nhand/anaconda/lib/python2.7/site-packages/pmesh/pm.py", line 119, in unsort
assert len(flatiter) == self.size

test_paint.py didn't even detect errors in DefaultPainter.py .

Could it be the error-code tests were problematic?

I fixed a bug in pmesh (0.0.18). These two should have been fixed now.
