1acd8e041c [CK Tile] gemm splitk two stage (#2697)
* Fix a typo

* Use std::variant to call run_gemm_example_with_layouts with the available layout variant combinations

* Use a unified run_gemm_example_prec_type for basic gemm and universal gemm

* Factor out run_gemm_example_prec_type

* Refactor argument parsing in gemm_splitk_two_stage_reduce.cpp

* Parse arguments outside of create_args

* Move the gemm operators to separate structs to facilitate their reuse

* Move the invokers to separate files to facilitate their reuse

* Rename the invoker files for consistency with the examples that use them

* Add fp32 support to the elementwise examples, and produce an error message for unsupported types

* Get rid of four unused variables

* Make two variables const

* Add support for different input-output type combinations in elementwise examples

* Test support for different input and output types in elementwise examples

* Add support for different operations in the elementwise unary tests

* Add support for UnaryConvert in the elementwise unary tests

* Add support for bf16 in elementwise examples, excluding unsupported type combinations

* Make some operator parameters const in ElementWiseKernel

* Remove some unnecessary include statements

* Implement a two-stage GEMM that does a type conversion in the second stage using the elementwise kernel

* Clear workspace instead of output when flushing the cache in SplitKTwoStageInvoker::gemm

* Fix formatting issues reported by clang

* Add back CK_TILE_USE_WMMA related changes

* Use the right prec type for bf16 in the universal GEMM and two stage split K examples

* Add some brackets

* Add some brackets

* Separate the clearing of the GEMM output memory from the cache flushing in the universal GEMM example

* Separate the clearing of the GEMM output memory from the cache flushing in the split K two stage example

* Fix formatting

* No need to call SetZero on ws_m_n_dev_buf here, as clear_gemm_output now does this as part of the kernel preprocessing

* Add fp16 data type to splitk two stage example

* Add preprocessing with optional cache flushing and clearing of output for k_batch > 1 to the basic GEMM example

* Elementwise with generalized nDims

* Adding the n-ary input tensor feature

* Generalize dimensions on top of inputs

* Add TFLOPS + remove std usage for tuples

* 1D basecase optimization

* Cleanup code + refactoring to a common interface

* Generalize to unary and add an example

* Cleanup, refactoring and commenting

* Suggestions for LWPCK-3170: elementwise kernel improvements

* Clang-format: remod.py

* Replace InputTensorType with XDataType as the type of input_tensors

* Add Tuple::apply and use it in ElementWiseKernel::operator to call operation with the exact number of arguments in xs

* Move examples to folder 19_elementwise

* Add missing copyright headers and fix some existing ones

* Replace an assert with throw std::runtime_error in elementwise example

* Avoid reading the output by using make_static_distributed_tensor for y_tile

* Removed two unused includes

* No need to move windows to the next block when each workgroup processes a single tile

* Only copy input tensors to the device

* Use get_warp_size to obtain warp size, and use ceiling division for grid size also for the unary example

* Adding output strides to the kernel, transposition example and update the other examples

* Changes made by remod.py

* Use default template parameter values for memory operation and coherence in a call to make_naive_tensor_view

* Move binary operations to include/ck_tile/ops/elementwise/binary_elementwise_operation.hpp

* Reuse generic reference binary/unary operation in examples + refactoring the transpose reference

* Fix comments in elementwise_example.cpp

- Refer to AMD terminology except when suggesting NVIDIA alternatives in parentheses
- ElementWiseTraits was renamed to ElementWiseShape
- Adopt suggestions made by Copilot when prompted to check for factual or typographical errors

* Simplify CMakeLists.txt and remove the unused variables this uncovers

* Rename a file and fix some copyright statements

* Changes made by script/clang-format-overwrite.sh

* Add basic unit test for ElementWiseKernel

* Remove left-over uninformative comment in apply unit test

* Changes made by clang-format-overwrite.sh

* fixup! Use default template parameter values for memory operation and coherence in a call to make_naive_tensor_view

* Clean up test_tuple_apply.cpp and test_elementwise_1d.cpp

* Use make_uniform_array_with_factory to define h_xs and d_xs_mems_owner as type std::array

* Use a DeviceMem constructor that calls get_element_space_size_in_bytes internally

* Move examples to folder 20_elementwise

* Reduced register pressure on the CK tile elementwise kernel + add 4d input example to be able benchmark against old CK

* Fix CLang formating

* Bump up the elementwise example folder number

* Elementwise: add padding + minor cleanup

* Add Vector Size inference + fix issue with wrong vectorization due to missing GuaranteedLastDimensionVectorStride setting in make_naive_tensor_view

* Add isSupportedArg to Elementwise kernel + addapt example and unit tests

* Fix clang-format on the unit test file
