If you are programmer you only have to write two functions: map and reduce. :)&nbsp; From what I understand Dyrad is even higher level in that it can describe a graph of operations that might take multiple maps and reduces otherwise. Basically it helps you write something more concise that might require a larger program with MapReduce. I think that's just the nature of Linq in action. Linq can represent a graph of operations in a single statement, to so easy to do with standard code. I don't think this signifies some mathematical difference between the two at the low level (I didn't get any hint that Dyrad could do parallelize things that MapReduce can't).</p> <p>&nbsp;</p> <p>But DyradLINQ might be the most awesome thing since slice bread, but right now the only significant difference to me about something like Hadoop or this DyradLINQ is I can not legally use DyradLINQ. I don't care if you told me DyradLINQ was worse the Hadoop, the fact that it is designed for .NET means I would use it. </p> <p>&nbsp;</p> <p>So you can sell it to me but quite frankly it's useless unless you license it better. Hadoop is fully open source and you can use it in commercial products. Why is DyradLINQ so restricted?</p> <p>&nbsp;</p>http://channel9.msdn.com/posts/Charles/Expert-to-Expert-Erik-Roger-Barga-Introduction-to-Dryad-and-DryadLINQ/?CommentID=479242Thu, 16 Jul 2009 19:37:25 GMThttp://channel9.msdn.com/posts/Charles/Expert-to-Expert-Erik-Roger-Barga-Introduction-to-Dryad-and-DryadLINQ/?CommentID=4792420http://channel9.msdn.com/479242/WebViewBug.aspx?EVT=0It was a somewhat interesting video. &nbsp; MapReduce is an in fact a fairly high level programming abstraction.
