<p>
This method basically takes given argument and splits it into a collection
of <span class="xref">Apache.Ignite.Core.Impl.Compute.IComputeJob</span> using provided grid size as indication of how many node are
available. These jobs will be randomly mapped to available Ignite nodes. Note that
if number of jobs is greater than number of Ignite nodes (i.e, grid size), the grid
nodes will be reused and some jobs will end up on the same Ignite nodes.</p>
