* tensorflow: finer-grained Shard parallelizationGravatar A. Unique TensorFlower2016-05-10
| | | | | | | | | | | | | | | | | | | | | | | | Provide finer-grained Shard parallelization for the new non-blocking thread pool. This significantly resembles the parallel for algorithm in eigen executors: we choose a good block size based on amount of work and parallel efficiency, and then use recursive division in halves.
