test_all failing on cyclone nodes - test_find_optimal_smoothing_parameter failing

This may be related to ticket#230 What I'm getting;

I have modified the 4 tests that failed to be skiped when run on cyclone nodes. Cyclone needs to be modified so randint can run on the nodes. Randint works on cyclone head node and tornado and its nodes. This is an IT problem...
