We exert a good deal of effort ensuring that the APIs we provide are consistent within Parallel Extensions as well as with the rest of the .NET Framework.  This is from many angles, including behavior and general design, but also naming.  So when there are slight differences in naming, it raises questions.One occurrence of such a ...

Attached to this post are the slides we presented. (It turns out that the PDC site does allow you to submit an evaluation for a precon.  If ...

PLINQ Ordering

There is a natural tension between ordering and performance in a parallel partitioning system such as PLINQ, which we addressed as guidance in the Dec07 CTP documentation:  “Although you can opt into ordering, this does come at a cost to performance because it constrains the options which PLINQ can use for executing a query, so it ...
