Microsoft is launching HPC++ CompFin Lab, an online HPC service aimed at providing academic computational finance programs with a rich analytic and simulation environment in the context of real market data.  Using this lab, professors will be able to develop models using .NET, Linq and SQL and deploy them via Sharepoint to a 256 core cluster, while students will utilize Excel to specify their experiments, seamlessly submit jobs to the cluster, and visualize the results.  As part of the lab, we are making available a 2TB data set from Reuters with 5 year rick by tick data for S&P500, daily and fundamental data for 10,000 stocks and Mortgage Back Securities pool data.  You can find more information, including screen-casts and white papers, on http://labs.microsofthpc.net/.
