- array shape is changed from (3, 1024, 1024) → (3, 8*512, 1024) 4M
- array generation is excluded from time measurement, only indexed subtraction contributes to time measurement
- do not pre-create random arrays, it is generated in each core... requires too much memory for all cores.
- run on sdfmilan047: ana-4.0.58-py3 [dubrovin@sdfmilan047:~/LCLS/con-py3]$ mpirun -n 80 python test-mpi-numpy-hist.py

- shape is decreased in size from (8*512,1024) to (2*512,1024) 1M
