a20b58845f CUDA_ARCH isn't always defined, so avoid relying on it too much when figuring out which implementation to use for reductions. Instead rely on the device to tell us on which hardware version we're running. 2016-08-03 10:00:43 -07:00

85699850d9 Add missing CUDA kernel to tensor scan op
The TensorScanOp implementation was missing a CUDA kernel launch.
This adds a simple placeholder implementation.

75c333f94c Don't store the scan axis in the evaluator of the tensor scan operation since it's only used in the constructor.
Also avoid taking references to values that may becomes stale after a copy construction.
