[CK_BUILDER] Fix two staging-compiler errors in CK builder
code (#4598)
This PR fixes two compiler warnings that report as errors with the
latest compiler:
1. In tensor descriptor, the `operator[]` accessor needs a
`[[clang::lifetimebound]]` attribute.
2. In the unit tests for device buffer, there is a test that explicitly
checks for an error on a pointer that went out of scope, so it needs a
to disable `-Wlifetime-safety-permissive` in the test code.
I ran the CK `smoke-builder` tests with the staging compiler to verify.
This adds some utilities to automatically generate UniqueInputs,
UniqueOutputs, alloc_inputs, alloc_outputs, and validate, based
on a Inputs::reflect() and Outputs::reflect().
This pull request builds on #3267 by proving the "validation" infrastructure, the means to compare a set of `Outputs`.
The design of the validation infrastructure is relatively straight forward:
- Each SIGNATURE should come with a `validate()` implementation, which should be implemented in a similar way that the other functions/types from `testing.hpp` are implemented.
- `validate()` returns a `ValidationReport`, which is a structure that keeps all relevant information about comparing the tensors from two `Outputs`. Note that crucially, `validate()` should not do any reporting by itself. Rather, glue logic should be implemented by the user to turn `ValidationReport` into a relevant error message.
- You can see this clue code for CK-Builder itself in `testing_utils.hpp`, its `MatchesReference()`. This functionality is relatively barebones right now, it will be expanded upon in a different PR to keep the scope of this one down.
The comparison is done on the GPU (using an atomic for now), to keep tests relatively quick. Some notable items from this PR:
- To help compare the tensors and with writing tests, I've written a generic function `tensor_foreach` which invokes a callback on every element of a tensor.
- For that it was useful that the `TensorDescriptor` has a rank which is known at compile-time, so I've changed the implementation of `TensorDescriptor` for that. I felt like it was a better approach than keeping it dynamic, for multiple reasons:
- This is C++ and we should use static typing where possible and useful. This way, we don't have to implement runtime assertions about the tensor rank.
- We know already know the rank of tensors statically, as it can be derived from the SIGNATURE.
- It simpifies the implementation of `tensor_foreach` and other comparison code.
- There are a lot of new tests for validating the validation implementation, validating validation validation tests (Only 3 recursive levels though...). For a few of those functions, I felt like it would be useful to expose them to the user.
- Doc comments everywhere.
* Add README.md for testing
* Add tensor_memory_manager.
* ck-builder: tensor memory manager rebase fixes
This fixes some issues caused by the API being changed recently.
Also, this streamlines the ckt namespace to always be ck_tile::builder::test,
as this is already being used by other tests
Really, this commit should be squashed into the previous,
but I'm keeping it separate for brevity.
* ck-builder: test arguments initial prototype
* ck-builder: test system initial prototype
* ck-builder: fix non-standardized copyright comments
* ck-builder: new prototype
* ck-builder: group testing inputs/outputs into a separate structure
This is basically the return of the tensor memory manager after all,
except that the design is more closely tied to the actual operation.
Using a struct allows us to add additional input/output tensors
without breaking code (by defaulting those new parameters). Note
that the tensors are split into a separate inputs/outputs because we
usually want to allocate the output _twice_: once for the real
computation and once for the reference computation.
* ck-builder: simplify prototype naming; start docs
* ck-builder: update testing readme
* ck-builder: testing documentation
* ck-builder: HipStatusMatcher
This matcher can be used to check HIP status codes and provide
nice and readable error messages.
* ck-builder: tensor_buffer.hpp tests
* ck-builder: conv_fwd.hpp tests
* ck-builder: add example end-to-end test in conv fwd 2d fp16
* ck-builder: simplify extent usage
* ck-builder: update testing doc
* ck-builder: skip end to end test on non-gfx9
* fix check_copyright_year interpreter
/bin/bash is not guaranteed to exist on Linux. Signed,
a NixOS user
* ck-builder: fix copyrights
* ck-builder: reduce conv fwd testing size
This test allocated 24GB of memory, too much for 16GB cards.
