Stephen Toub - MSFT
PLINQ enables developers to scale up computations in order to leverage the multiple cores available in modern hardware. For many problem domains, this is quite useful and sufficient. What happens, however, when a workload being processed is so big that even a manycore machine is insufficient to adequately handle the load? This can be the case ...
