Big data is a rapidly growing customer need. The HPC team is enabling commodity clusters running Windows HPC Server to address the “unstructured” part of the big data workload using the Dryad distributed runtime. We show demos of Dryad and Windows HPC Server,discuss how Dryad and Microsoft SQL Server can be combined in end-to-end solutions that handle both structured and unstructured data,and discuss how to administer Windows HPC Server clusters running Dryad applications.
