MapReduce: LINQ to HPC vs Daytona ?

Using LINQ to HPC, its also possible to implement a MapReduce
var mapped = source.SelectMany(mapper);
var groups = mapped.GroupBy(keySelector);
return groups.SelectMany(reducer);why is MS Research working on another MapReduce implementation (project Daytona - http://research.microsoft.com/en-us/projects/azure/daytona.aspx ), when LINQ to HPC is already cloud ready and capable of implementing MapReduce?

Hi,
Sorry for the late reply.
Linq to HPC and Daytona have different designs and focus. With Daytona, it is easy to do Iterative MapReduce.
Another news: LinqToHPC project was dropped at Microsoft. See web site: http://social.microsoft.com/Forums/en-US/windowshpcdevs/thread/43e8a6d3-eb7e-4ddf-9e54-189b487ef0df
Daytona is still in active and supported mode.
Thanks.
