* Begin introducing NUMA support for CPU threads and memoryGravatar A. Unique TensorFlower2018-06-29
| | | | | | | | | | | | | | by extending the core/platform API with some basic functionality. The new functions allow: 1. Determining how many NUMA nodes are available. 2. Setting the executing thread to be bound to a particular node, or not bound at all. 3. Allocating memory affiliated with a particular node. This change introduces the API only, there is not yet a real implementation. PiperOrigin-RevId: 202724194

* Allow gradients() calls from inside a function wrt captured tensors.Gravatar Skye Wanderman-Milne2018-06-29
| | | | | | | | The overall approach is to teach the gradients code how to traverse the implicit edges between captured external tensors and ops inside the function body. PiperOrigin-RevId: 202705929

* Auto tracking for Python lists assigned to attributes of Model/CheckpointableGravatar Allen Lavoie2018-06-29
| | | | | | | | | | | | Conceptually lists just get replaced with a list-like wrapper. A shallow copy is maintained for error checking (since appends to it aren't monitored, we can't do restore-on-create for variables unless it's being modified through the wrapper). There are lots of other details. I gave up on generalizing our isinstance(obj, (list, tuple)) checks and just subclassed list. Behaving like a list means the type should be unhashable, which requires some workarounds when we're collecting objects (object-identity collections, and object-identity versions of weak reference containers). Adds a decorator for exempting whole methods from automatic dependency tracking so we don't need to track down every last self.inputs = [] statement to avoid polluting dependencies. There's a TODO for tuples and dictionaries. PiperOrigin-RevId: 202703271

* Add a method that calls the python function backing a _PolymorphicFunction.Gravatar Akshay Agrawal2018-06-29
| | | | | | | | | This is at the least useful for testing behavioral differences between a wrapped Python function and the corresponding graph functions. Prior to this change, decorating a Python function with `@function.defun` would render the Python function inaccessible. PiperOrigin-RevId: 202685407

* [XLA] Add key-value version of Sort HLO.Gravatar Michael Kuperstein2018-06-29
| | | | | | This is only currently implemented in the evaluator backend, and even that implementation is partial - the key and value type must match. PiperOrigin-RevId: 202673122

* [tf.data] Optimize the implementation of DeserializeSparseOp<Variant>.Gravatar Derek Murray2018-06-29
| | | | | | The most expensive part of this kernel is the index construction. The optimized implementation builds the new index matrix at most once, rather than performing up to 3 passes (adding a leading dimension, `SparseTensor::Concat()` and `Reshape()`), and adds a specialized codepath for the common case of stacking together rank-1 SparseTensors. PiperOrigin-RevId: 202669432

* Handle nested tuples in GpuTransferManager.Gravatar Adrian Kuegel2018-06-29
| | | | | | | | This became necessary when the TOKEN primitive type was added. In some models, an existing tuple T is extended to (T, token[]). Also add the TOKEN case to a switch statement where it was missing. PiperOrigin-RevId: 202643759
* [XLA] Add new helper xla::Iota().Gravatar Peter Hawkins2018-06-29
| | | | | | | | Start a new client library "numeric", after the C++ <numeric> header where std::iota lives. [TF:XLA] Replace uses of XlaHelpers::Iota() with xla::Iota(). Add a helper to get the XLA type of an operator input. PiperOrigin-RevId: 202636221
* [XLA] Make XlaBuilder op construction methods private. Change remaining ↵Gravatar Peter Hawkins2018-06-29
