[ROCm/composable_kernel commit: d405641f06]
Builder
This directory contains the experimental builder feature for composable_kernel.
- Status: In development (October - November 2025)
Overview
The builder provides a high-level, semantically-clear interface for constructing composable kernel operations, with an initial focus on convolution kernels for MIOpen. It leverages modern C++20 features (such as POD structs as non-type template parameters, concepts, and designated initializers) to simplify kernel instantiation and improve developer experience.
This project is a prototype for a more general builder pattern for all of composable_kernel (CK) and CKTile, but is currently limited to formalizing the interface between MIOpen and CK.

CMake Configuration
To enable the experimental builder, configure your build with:
cmake \
-D CMAKE_PREFIX_PATH=/opt/rocm \
-D CMAKE_CXX_COMPILER=/opt/rocm/bin/hipcc \
-D CMAKE_BUILD_TYPE=Release \
-D GPU_TARGETS="gfx942;gfx950" \
-D CK_EXPERIMENTAL_BUILDER=ON \
-D CMAKE_CXX_STANDARD=20 \
-G Ninja \
..
Building and testing
During development, all CK Builder tests can be built with command
ninja test_ckb_all
To execute all tests, run
ls bin/test_ckb_* | xargs -n1 sh -c
Some tests involve building old CK convolution factories, which will take a long time. Hence, one might want to build only single test targets. For example
ninja test_ckb_conv_builder && bin/test_ckb_conv_builder
When adding new tests, please follow the convention where the CMake build target starts with a prefix test_ckb.
This allows us to filter out the CK Builder tests from the set full CK repository tests.
Also, the test_ckb_all target that builds all CK Builder tests relies on having the test_ckb prefix on the CMake build targets.
