[CK_BUILDER] Update developer notes in the CK Builder source
directories (#5038)
## Motivation
This PR updates the developer notes for the CK Tile builder. It captures the current state of the implementation in more detail, and frames the description around the need to have true facade.
There is no functional change, only better alignment of developer notes with the current code.
This doc clearly explains the current technical debt: that we have created many facades that expose
the implementation details. There is an expanded section on reflection that explains how unified
reflection will help clarify the unified builder design.
Additional changes are just better accounting for the current state of the code, including previously
undocumented operations. A few typos and cosmetic issues are cleaned up, too.
* ck-builder: tensor copy function
This function copies one tensor to another, so that the memory
layout can be changed between them.
* ck-builder: fix ck::bhalf literals
These types don't work properly.
* ck-builder: abstract compare_elements in gpu_verification.hpp and make builder use it
This reduces the amount of duplicated code a bit.
* ck-builder: add flat tensor iterator
This "iterator" type pretends to be a pointer, useful for passing
tensors to functions expecting pointer-like types.
* ck-builder: integrate validation with ck gpu verification
By templating the gpu_verify function over iterators, we can use
the new FlatTensorIterator to adapt the function to multi-
dimensional tensors without changing either implementation
too much.
* ck-builder: add check_by_accumulations
This changes the gpu_verification.hpp code to also accept "iterator"
types for the relevant gpu_verify and gpu_reduce_max functions.
* ck: fix test_gpu_verification GenerateRandomData for bhalf
is_integer_it<bhalf_t> yields true, but it is not actually
an integer.
* ck: make gpu_verification kernels be proper persistent kernels
Previously these were using a hardcoded value for the grid size. This
commit changes that so that the grid size is automatically derived
from the kernel's occupancy and the number of multiprocessors on
the GPU.
* ck: clean up gpu_verification.hpp using block_reduce
This implements a small generic block reduce function, and rewrites
the rest of gpu_verification.hpp using that function to clean it up
a bit.
* ck-builder: doc typos
* ck-builder: update testing readme with validation interface.
* ck-builder: rebase fixes + review comments
* ck-builder: fix device integer generation with float types
Passing bfloat here causes a nans due to type_convert performing
a bitcast.
* ck: another bhalf_t bug
CK expects that int-generation with ck::bhalf_t yields bhalf integers,
not unsigned integers. This makes the logic of FillUniformRandInteger
compatible with GeneratorTensor_2<InDataType>, however idiotic that
may be.
This is mostly adjustments to enum values so that the docs align correctly with the current code.
Also updated the calendar scope of the project to extend through March 2026.
* 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.
