[PyTorch] RFC: Add tuple inline storage #64066

swolchok · 2021-08-26T23:44:46Z

Stack from ghstack:

I noticed a bunch of time being spent heap-allocating Tuples
in the unpickler. 1-, 2-, and 3-element Tuples are apparently common
enough that they get their own bytecode instructions, so I decided to
try also giving them their own representation. We store up to 3
IValues inline in Tuple rather than doing a second heap allocation
for a std::vector<IValue>.

aten/src/ATen/core/ivalue_inl.h

 struct TORCH_API Tuple : c10::intrusive_ptr_target {
 private:
-  std::vector<IValue> elements_;
+  TupleElements elements_;


Why do we need that new TupleElements class instead of just using a c10::SmallVector<IValue, 3>?

lw · 2021-08-27T08:52:23Z

torch/csrc/distributed/autograd/rpc_messages/propagate_gradients_req.cpp

  autogradMessageId = tupleElements.back().toInt();
-  tupleElements.pop_back();
  autogradContextId = tupleElements.back().toInt();
-  tupleElements.pop_back();


Why are you removing these pop_back() calls? Unless I'm missing something obvious, without them autogradMessageId and autogradContextId will be the same. This can't possibly be correct. Didn't any test catch it? CC @pritamdamania87

Yes, this doesn't seem right.

torch/csrc/jit/api/module.cpp

  // call forward pre_hooks
  for (const auto& pre_hook : pre_forward_hooks) {
-    auto tuple_input = c10::ivalue::Tuple::create(inputs);
+    auto tuple_input = c10::ivalue::Tuple::create(std::move(inputs));


I don't think you can safely move inputs since it could be re-used by later loop iterations.
