Research direction

Start by locating the existing distarray test modules and the test harness for launching IPython engines. Review how random inputs, distributed dimensions, ufuncs, and reductions are currently tested. Done means a separate fuzz-testing module covers the requested engine counts, array sizes, distribution mixes, fundamental operations, and listed edge cases.

Written by the indexing model from the issue text.

Description

enhancement

For robustness, it would be good to have a separate test module that:

  • is run with a random number of IPython engines (between 1 and 20 or so, inclusive)
  • creates random distarrays with random sizes in each dimension (between 0 and 1e6, inclusive)
  • with a random mix of undistributed, block distributed, and block cyclic distributed dimensions
  • that tests ufuncs, reductions, and other fundamental stuff

We could test the edge cases in a separate test class as well -- size of zero in one or more dimensions, all dimensions undistributed, using a view with just one target /engine, etc.
