These utilities enable a clean, expressive **Given-When-Then** (Given-When-Then) testing pattern that separates test setup, execution, and validation. + +## Overview + +Testing GPU kernels typically involves significant boilerplate: allocating device memory, initializing test data, launching kernels, and validating results. The utilities in this directory abstract away these repetitive tasks, allowing you to focus on defining test cases and verifying correctness. + +The core components are: + +- **`Args`**: A struct template that holds runtime parameters for a specific test case +- **`TensorMemoryManager`**: A helper class that manages GPU memory allocation and initialization +- **`Validator`**: A utility that performs on-GPU validation and integrates with GoogleTest/GoogleMock + +Together, these components enable a structured approach to kernel testing that mirrors the Given-When-Then pattern commonly used in behavior-driven development. + +## The Given-When-Then Testing Pattern + +The Given-When-Then pattern organizes tests into three distinct phases: + +1. **Given**: Set up the preconditions and test data +2. **When**: Execute the action being tested +3. **Then**: Verify the expected outcome + +This structure makes tests easier to read, write, and maintain. Each phase has a clear purpose, and the testing utilities are designed to support this workflow. + +### Given: Defining the Test Case + +The "Given" phase establishes the context for your test. This includes both the compile-time characteristics of the kernel and the runtime parameters for the specific test case. + +#### `ConvSignature` + +The `ConvSignature` defines the **mathematical contract** that the kernel must satisfy. It specifies compile-time properties such as: + +- Spatial dimensionality (1D, 2D, or 3D) +- Convolution direction (Forward, Backward Data, Backward Weight) +- Tensor memory layout (e.g., NHWC, NCHW) +- Data types (FP32, FP16, BF16, etc.) +- Fused element-wise operations (e.g., Bias, ReLU) + +The signature is enforced at compile time using C++20 concepts, ensuring type safety and enabling compile-time optimizations. + +```cpp +struct ConvSignature { + static constexpr int spatial_dim = 2; + static constexpr ck_tile::builder::ConvDirection direction = + ck_tile::builder::ConvDirection::FORWARD; + static constexpr ck_tile::builder::GroupConvLayout2D layout = + ck_tile::builder::GroupConvLayout2D::NHWGC_GKYXC_NHWGK; + static constexpr ck_tile::builder::DataType data_type = + ck_tile::builder::DataType::FP16; + static constexpr ck_tile::builder::ElementwiseOperation elementwise_operation = + ck_tile::builder::ElementwiseOperation::NONE; + static constexpr ck_tile::builder::GroupConvDeviceOp device_operation = + ck_tile::builder::GroupConvDeviceOp::IMPLICIT_GEMM; +}; +static_assert(ck_tile::builder::ConvSignatureDescriptor); +``` + +#### `Args` + +The `Args` struct template provides the **runtime parameters** for your test case. It is parameterized by the `ConvSignature` and contains fields for tensor dimensions, strides, dilations, and other dynamic properties. + +```cpp +ck_tile::testing::Args args = { + .batch_size = 128, + .num_groups = 1, + .input_channels = 64, + .output_channels = 128, + .input_height = 56, + .input_width = 56, + .filter_height = 3, + .filter_width = 3, + .stride_height = 1, + .stride_width = 1, + .dilation_height = 1, + .dilation_width = 1, + .pad_height = 1, + .pad_width = 1, +}; +``` + +#### `TensorMemoryManager` + +The `TensorMemoryManager` is the primary tool for the "Given" phase. It takes the `Args` and handles all GPU memory management: + +- **Allocation**: Automatically allocates device memory for all input and output tensors based on the signature and runtime dimensions +- **Initialization**: Provides methods to initialize tensor data directly on the GPU, avoiding costly host-to-device transfers +- **Access**: Exposes tensor pointers and metadata needed for kernel execution and validation + +```cpp +ck_tile::testing::TensorMemoryManager dev_mem(args); +dev_mem.initialize(); // Initialize tensors on GPU with default pattern +``` + +The `TensorMemoryManager` can initialize data with various patterns (e.g., random values, sequential values, constant values) to suit different testing needs. + +### When: Executing the Kernel + +The "When" phase is where you execute the kernel being tested. This involves selecting an algorithm and using the `Builder` to generate the kernel. + +#### `ConvAlgorithm` + +The `ConvAlgorithm` defines the **implementation strategy** for the kernel. It specifies low-level details such as: + +- Thread block dimensions and tile sizes +- GEMM implementation (XDL or WMMA) +- Data transfer vectorization +- Pipeline scheduling + +```cpp +struct ConvAlgorithm { + // Thread block configuration + static constexpr auto thread_block = /* ... */; + + // Gridwise GEMM configuration + static constexpr auto gridwise_gemm = /* ... */; + + // Block transfer configuration + static constexpr auto block_transfer = /* ... */; + + // Additional tuning parameters + // ... +}; +static_assert(ck_tile::builder::ConvAlgorithmDescriptor); +``` + +#### Building and Running the Kernel + +The `Builder` combines the `ConvSignature` (what to compute) with the `ConvAlgorithm` (how to compute it) to generate a runnable kernel operation. + +```cpp +using ConvOp = ck_tile::builder::Builder::op; + +// Launch the kernel with tensor pointers from TensorMemoryManager +ConvOp::Run( + dev_mem.input_ptr(), + dev_mem.weight_ptr(), + dev_mem.output_ptr(), + args +); +``` + +### Then: Verifying the Results + +The "Then" phase validates that the kernel produced the expected output. + +#### `Validator` + +The `Validator` class encapsulates the validation logic. It performs on-GPU correctness checks by comparing the kernel's output against a reference implementation or expected properties. + +```cpp +ck_tile::testing::Validator validator(args, dev_mem); +``` + +The `Validator` provides methods that return GoogleMock matchers, enabling clean integration with GoogleTest: + +```cpp +EXPECT_THAT(validator.result(), validator.is_ok()); +``` + +The `is_ok()` matcher checks that the output is numerically correct within acceptable tolerances. The `Validator` can also provide more detailed diagnostics, such as: + +- Maximum absolute error +- Maximum relative error +- Number of mismatched elements +- Specific locations of errors + +## Complete Example + +Here's a complete test that demonstrates the Given-When-Then pattern: + +```cpp +#include +#include "ck_tile/builder/conv_signature_concepts.hpp" +#include "ck_tile/builder/conv_algorithm_concepts.hpp" +#include "ck_tile/builder/conv_builder.hpp" +#include "ck_tile/testing/tensor_memory_manager.hpp" +#include "ck_tile/testing/validator.hpp" + +// Define the convolution signature +struct ConvSignature { + static constexpr int spatial_dim = 2; + static constexpr ck_tile::builder::ConvDirection direction = + ck_tile::builder::ConvDirection::FORWARD; + static constexpr ck_tile::builder::GroupConvLayout2D layout = + ck_tile::builder::GroupConvLayout2D::NHWGC_GKYXC_NHWGK; + static constexpr ck_tile::builder::DataType data_type = + ck_tile::builder::DataType::FP16; + static constexpr ck_tile::builder::ElementwiseOperation elementwise_operation = + ck_tile::builder::ElementwiseOperation::NONE; + static constexpr ck_tile::builder::GroupConvDeviceOp device_operation = + ck_tile::builder::GroupConvDeviceOp::IMPLICIT_GEMM; +}; +static_assert(ck_tile::builder::ConvSignatureDescriptor); + +// Define the convolution algorithm +struct ConvAlgorithm { + // Algorithm configuration details... + // (Omitted for brevity) +}; +static_assert(ck_tile::builder::ConvAlgorithmDescriptor); + +TEST(ConvolutionTest, Forward2D_FP16) { + // ===== GIVEN: Set up the test case ===== + + // Define runtime parameters + ck_tile::testing::Args args = { + .batch_size = 128, + .num_groups = 1, + .input_channels = 64, + .output_channels = 128, + .input_height = 56, + .input_width = 56, + .filter_height = 3, + .filter_width = 3, + .stride_height = 1, + .stride_width = 1, + .dilation_height = 1, + .dilation_width = 1, + .pad_height = 1, + .pad_width = 1, + }; + + // Allocate and initialize GPU memory + ck_tile::testing::TensorMemoryManager dev_mem(args); + dev_mem.initialize(); + + // ===== WHEN: Execute the kernel ===== + + using ConvOp = ck_tile::builder::Builder::op; + + ConvOp::Run( + dev_mem.input_ptr(), + dev_mem.weight_ptr(), + dev_mem.output_ptr(), + args + ); + + // ===== THEN: Verify the results ===== + + ck_tile::testing::Validator validator(args, dev_mem); + EXPECT_THAT(validator.result(), validator.is_ok()); +} +``` + +## Benefits of This Approach + +1. **Clarity**: The Given-When-Then structure makes tests self-documenting. Each phase has a clear purpose. + +2. **Reduced Boilerplate**: The utilities handle memory management, initialization, and validation, eliminating repetitive code. + +3. **Type Safety**: The use of C++20 concepts ensures that signatures and algorithms are well-formed at compile time. + +4. **Flexibility**: The `Args` struct can be easily extended to support different test scenarios, and the `TensorMemoryManager` supports various initialization patterns. + +5. **Integration**: The `Validator` integrates seamlessly with GoogleTest/GoogleMock, providing familiar assertion syntax. + +6. **Maintainability**: Changes to the testing infrastructure are localized to the utility classes, not scattered across individual tests. + +## Future Enhancements + +Potential improvements to the testing utilities include: + +- Support for custom reference implementations in the `Validator` +- Performance benchmarking utilities +- Automatic test case generation from parameter ranges +- Enhanced error reporting with visual diffs +- Support for multi-GPU testing scenarios diff --git a/experimental/builder/include/ck_tile/builder/testing/conv_args.hpp b/experimental/builder/include/ck_tile/builder/testing/conv_args.hpp new file mode 100644 index 0000000000..a3b3a81ad8 --- /dev/null +++ b/experimental/builder/include/ck_tile/builder/testing/conv_args.hpp @@ -0,0 +1,195 @@ +// Copyright (c) Advanced Micro Devices, Inc.
