- Construct a distributed array. The parameter \"init\" is a function
- that accepts a tuple of index ranges. This function should allocate
- a local chunk of the distributed array and initialize it for the
- specified indices. \"dims\" is the overall size of the distributed
- array. \"procs\" optionally specifies a vector of process IDs to
- use. If unspecified, the array is distributed over all worker
- processes only. Typically, when running in distributed mode, i.e.,
- \"nprocs() > 1\", this would mean that no chunk of the distributed
- array exists on the process hosting the interactive julia prompt.
- \"dist\" is an integer vector specifying how many chunks the
- distributed array should be divided into in each dimension.
