Our concept-base conversions are fragile and too complex. We want to refactor to straightforward functions
for each intance trace class template. This change adds unit test coverage to make that refactoring safer.
* ck-builder: explicitly delete forward declarations
Before, these functions were seen as a forward declaration for an existing function.
If no actual implementation overload could be found, these would be selected and
a linker error or warning would be generated. By marking these functions as explicitly
deleted, they incorrect invocations are generated as compile error instead.
* ck-builder: ckt::run plumbing for reference conv
This implements the ckt::run plumbing for the reference convolution
implementation and sets up the first complete end-to-end test.
* ck-builder: make validation system check for all-zeros
When both the actual and reference output are both all zero bits,
there is probably something wrong in the test framework.
* ck-builder: proper implementation+tests for TensorDescriptor::is_packed
* ck-builder: fix typos
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.
Refactors the way the number of XDL (matrix multiply-accumulate) instructions per wave is calculated and used in the grouped convolution forward implementations, especially to better support WMMA (Wave Matrix Multiply-Accumulate) instructions and 16x16 tiles.
The changes use MXdlPerWave instead of NXdlPerWave to increase number of waves per M dim.
Introduces a polymorphic describe() method to BaseOperator that enables runtime introspection of kernel configurations through a unified interface.
Key changes:
* Add virtual describe() method to BaseOperator returning Description objects
* Implement describe() in 6 device operation classes (conv fwd/bwd variants)
* Create conv_describe.hpp with factory function for ConvDescription
* Extract type definitions to conv_types.hpp to resolve circular dependencies
* Add InstanceStringDescription for kernels without full ConvDescription support
Other Improvements:
* Update tests to use describe() instead of GetInstanceString()
* Remove circular dependency include from conv_traits.hpp
* Add ODD_C to ConvFwdSpecialization enum and fix OddC mapping
* Replace silent fallback in conv_layout() with compile-time error
This provides a foundation for runtime kernel introspection and better tooling support for analyzing and debugging kernel configurations.
* 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.
