* [XLA] Include kConvolution in the dot-add liveness optimizationGravatar David Majnemer2017-11-10

* Correct an IndexedSlices-related test in replicate_model_fn_test.py.Gravatar Igor Saprykin2017-11-10
| | | | | | I attempted to exercise compute_sum_on_device(IndexedSlices) via the DNNCLassifier test per reviewer's suggestion. This changelist is way to do it correctly. I verified that it indeed triggers the required codepath by adding logging and removing compute_sum_on_device(IndexedSlices) support. PiperOrigin-RevId: 175303333

* [XLA:CPU] Make one of the tile dimensions in the LLVM IR GEMV tunable.Gravatar Sanjoy Das2017-11-10
| | | | | | | | | | | | The tiling dimension corresponding to the number of vector registers in the tile can be changed easily. Expose this value as a backend specific flag so that we can experiment with it to find a good default value. This CL also fixes a bug exposed by a variable tiling factor in the row major GEMV implementation. This wasn't caught before because having tile_rows == tile_cols hides the bug.

* Get rid of IteratorBase::is_exhausted flag since it is not possible to rely ↵Gravatar Saurabh Saxena2017-11-10
| | | | | | | | | | | | | on it unless we lock each call to GetNext which is not preferable. Each iterator now handles saving/restoring exhausted state. As a guideline, we always reset the input_impl(s) when they get exhausted. This can be used as an indicator of exhausted-ness for non-terminal iterators. Also reduces memory overhead. Each iterator should also handle calls to GetNextInternal when it is exhausted. Fixed this for some datasets. Also fix a bug in dataset_serialization_test_base. We were not saving a checkpoint after exhausting the iterator so verify_exhausted_iterator was not really testing restoring an exhausted iterator. PiperOrigin-RevId: 175253023
* Add bfloat support to XLA.Gravatar Yunxing Dai2017-11-10
| | | | | | This is necessary in providing bfloat support in GPU backend. RELNOTES: bfloat support is now added to XLA infra. PiperOrigin-RevId: 175252067
* [XLA] Don't deemphasize nodes inside of subcomputations in dumped XLA graphs.Gravatar Justin Lebar2017-11-10
| | | | | | | | | | Nodes inside of subcomputations (e.g. fusion computations) are always printed by the HLO graph dumper. Before this change, the dumper was not fully aware of this fact, leading it to mark as "deemphasized" (i.e. draw as gray with a dashed outline) nodes that had no business of being deemphasized. PiperOrigin-RevId: 175247474
* Hlo parser: support padding.Gravatar A. Unique TensorFlower2017-11-10
| | | | | | Also, give PaddingConfig its own ToString format. PiperOrigin-RevId: 175239832
* [StreamExecutor] LOG(ERROR) the driver version when cudnnCreate fails.Gravatar Justin Lebar2017-11-10
| | | | | | | | | Previously we LOG(INFO)'ed the driver version, which meant it wouldn't be printed unless you passed --logtostderr. But this information is pretty important, especially since cudnnCreate failing is likely to be a fatal error. PiperOrigin-RevId: 175235628

* De-flakify and re-enable tests in replicate_model_fn_test.py.Gravatar Igor Saprykin2017-11-10
| | | | | | | | "Reduce metric variables" operation is a single operation across all metric variables, which means it is across all eval metrics. Previously, an update op for every eval metric was conditioned on a copy of overall "reduce metric variables" op. The latter was meant to be idempotent and thus the end result was supposed to be correct. However, "reduce metric variables" op consists of a number of variable assignments and thus is not atomic. If execution of two "reduce metric variables" ops interleaves, then the end result might come out to be incorrect. This caused flakiness in replicate_model_fn_test.py. To fix the problem, there is now a single copy of the "reduce metric variables" and every eval metric is associated with that single instance. PiperOrigin-RevId: 175232016

* Make LLVMCompilerTest less stateful.Gravatar Sanjoy Das2017-11-10
| | | | | | | | | | | | Instead of assigning the pre and post optimization to a singleton xla::Compiler object, prefer creating a short-lived CpuCompiler or a GpuCompiler instance on the stack. Without this change, adding a second test case on the (Cpu|Gpu)Compiler in the same process triggers a use-after-free. (Btw, LLVMCompiler should really be spelled LlvmCompiler per Google C++ style, I'll do that rename shortly). PiperOrigin-RevId: 175218617
* [TF:XLA] Clean up unused XLA options and functions.Gravatar A. Unique TensorFlower2017-11-10

* Adds streaming_dynamic_auc to Tensorflow contrib metrics. This metric ↵Gravatar A. Unique TensorFlower2017-11-10
| | | | | | differs from streaming_auc because it uses every prediction as a threshold rather than linearly spaced fixed thresholds. PiperOrigin-RevId: 175217002

* Limit internal fragmentation in BFCAllocator to 128mb per allocation.Gravatar Justin Lebar2017-11-10
| | | | | | | | | | Previously, if you had a very large allocation, it would round up to the next power of 2, and then, if this didn't fit in your GPU's available memory, eat all remaining memory in the device. Now we waste at most 128mb of memory in a large alloc. PiperOrigin-RevId: 175209995

* `replicate_model_fn` supports aggregating gradients in IndexedSlices.Gravatar Igor Saprykin2017-11-10
| | | | | | | | `gradients.gradients` may return computed gradients in IndexedSlices as opposed to a Tensor: https://github.com/tensorflow/tensorflow/blob/r1.4/tensorflow/python/ops/gradients_impl.py#L881. `replicate_model_fn` currently uses math_ops.add_n to aggregate gradients from all towers. It doesn't work with IndexedSlices and thus needs to be handled separately. PiperOrigin-RevId: 175194893
