@Tiramisu most sparse networks like DBNs are modeled as graphs and hence Dmitriy had mentioned a graph-based solution.
The question for you is "What/Which platform is of most interest to u - a graph-based solution or an algebraic solution? " If its an algebraic solution you are looking for, Mahout provides the physical and logical operators for that and we are also in the process of rolling out native physical operators in the next release. I believe (correct me here) that you are trying to use matrix multiplications for ur DBN solution, if so the suggestion would be to create a javacpp - MPI bridge. Based on your interest and your requirements, we can take this conversation further. Thanks for reaching out.
