This fix affects the distributed runtime; DirectSession use is unaffected. Before this change, an iterator that used a background prefetching thread might attempt to use a captured FunctionLibraryRuntime from a subgraph that had been deregistered (and hence its FunctionLibraryRuntime would have been deleted). This change introduces a mechanism for "cloning" the necessary parts of the FunctionLibraryRuntime so that it can be owned by the IteratorResource.

The convolution algorithms returned from the stream executor have a flag for whether tensor_ops is enabled. This flag is used when running each algorithm during auto-tunning. However, this flag is not currently represented in the CustomCall representing the auto-tune result. As a result, the algorithm may be run differently after auto-tune. This change adds a constant to the CustomCall for cudnn convolution algorithm selected by auto-tune, to represent whether tensor_ops is enabled during auto-tune. This information is used by convolution thunk to ensure that the algorithm is run with the same flag after auto-tune.

This reduces the duration during which these constants are semantically represented as floats on the host side and are subject to fast-math-like behavior. This is especially important in cases where the exact bit representation of the floating point constant is significant, but also makes progress towards ensuring that e.g. build XLA with -ffast-math does not change the IR we generate.

} -- GitLab From 7575f334ee0879825ceed23928f5e99d0f71b5f8 Mon Sep 17 00:00:00 2001 From: Justin Lebar Date: Tue, 13 Feb 2018 17:16:29 -0800 Subject: [PATCH 151/629] [XLA:GPU] Don't crash when the root instruction of a computation is a multi-output fusion node, and avoid some pointer chasing with tuples. Previously, the kernels we generated would have one argument per *top-level* buffer of the input/output. This was fine for inputs. But it doesn't work for outputs: Imagine you're a node that returns a tuple -- e.g. multi-output fusion -- if all you get is a pointer to the top-level buffer of your output (which should contain pointers to the lower-level buffers at some point, but at the moment is just empty), how are you supposed to figure out where to write your output? (This usually worked because most of the time your output would live inside of the big XLA temp buffer, and kernels always get a pointer to that.) Now we pass all the buffers, top-level and otherwise, to our kernel. In addition, we're now willing to dereference statically tuples that live entirely in XLA's temp buffer. Pointers in input tuples must still be dereferenced dynamically, because the caller has the option of giving us these values or not when invoking XLA. This change makes some parts of BufferAssignment/BufferAllocations more truthful. Previously, if you passed a tuple-shaped input to XLA, we'd say in BufferAllocations that the pointer for some subshape of the param was the *top-level tuple pointer*. XLA then knew that this was a lie and would dereference it accordingly. Now we have an explicit notion of a BufferAllocation pointing to a subshape of an input parameter.

No public methods are exposed, and I've attempted to not throw any errors on __setattr__. Allows dynamic dependencies (track after restore) and restoring variables on assignment to a Checkpointable object, and includes the protocol buffer modifications necessary for saving information with each object. There are still some prominent TODOs: - Stop modifying the graph after the first save/restore (likely cache ops in Checkpointable objects) - Add some overridable methods for saving Python strings when restore() is called, fed when graph building rather than embedded as constants in the graph - Work on the initialization story for graph building. Currently the unit tests rely on collections for this. - Support for more objects, move the prototype modifications in checkpointable_test to core. The diff is larger than I was hoping (mostly deletions and unit tests); that could be reduced a bit (or at least "lines added" converted to "lines deleted") by diffbasing on cl/180950921, which was my first attempt at dynamic dependencies. This CL is more of a re-write than a modification, so sending that one out seems a bit silly. The unit tests are still good, though.
