Letting GPUs run free by Dan Olds.
From the post:
One of the most interesting things I saw at SC11 was a joint Mellanox and University of Valencia demonstration of rCUDA over Infiniband. With rCUDA, applications can access a GPU (or multiple GPUs) on any other node in the cluster. It makes GPUs a sharable resource and is a big step towards making them as virtualisable (I don’t think that’s a word, but going to go with it anyway) as any other compute resource.
This is a big deal. To me, the future of computing will be much more heterogeneous and hybrid than homogeneous and, well, some other word that means ‘common’ and begins with ‘H’. We’re moving into a mindset where systems are designed to handle particular workloads, rather than workloads that are modified to run sort of well on whatever systems are cheapest per pound or flop.
