Hi John, 

Thanks for your reply

how do I convert this array here to a SharedVariableArray?

VariableArray<Vector> phi = Variable.Array<Vector>(topicsNumRange);

Hi Freddy

Assuming you split the data into NumChunks chunks, the code would look something like this:

using DirichletArray=DistributionRefArray<Dirichlet, Vector>;
DirichletArray phiPrior =  new DirichletArray(new Dirichlet(beta));
Range TopicsNum = new Range(K);
SharedVariableArray<Vector> sharedPhi = SharedVariable<Vector>.Random(TopicsNum, phiPrior);
Model = new Model(NumChunks);
VariableArray<Vector> phi = sharedPhi .GetCopyFor(Model)

Then use phi as before in your model. You will have to explicitly do several passes, looping over the chunks as shown in the documented scalar example.
