2. CK docker hub#
2.1. Why do I need this?#
To make our lives easier and bring Composable Kernel dependencies together, we recommend using docker images.
2.2. So what is Composable Kernel?#
Composable Kernel (CK) library aims to provide a programming model for writing performance critical kernels for machine learning workloads across multiple architectures including GPUs, CPUs, etc, through general purpose kernel languages, like HIP C++.
To get the CK library:
git clone https://github.com/ROCmSoftwarePlatform/composable_kernel.git
run a docker container:
docker run \
-it \
--privileged \
--group-add sudo \
-w /root/workspace \
-v ${PATH_TO_LOCAL_WORKSPACE}:/root/workspace \
rocm/composable_kernel:ck_ub20.04_rocm5.3_release \
/bin/bash
and build the CK:
mkdir build && cd build
# Need to specify target ID, example below is for gfx908 and gfx90a
cmake \
-D CMAKE_PREFIX_PATH=/opt/rocm \
-D CMAKE_CXX_COMPILER=/opt/rocm/bin/hipcc \
-D CMAKE_CXX_FLAGS="-O3" \
-D CMAKE_BUILD_TYPE=Release \
-D GPU_TARGETS="gfx908;gfx90a" \
..
and:
make -j examples tests
To run all the test cases including tests and examples run:
make test
We can also run specific examples or tests like:
./bin/example_gemm_xdl_fp16
./bin/test_gemm_fp16
For more details visit CK github repo, CK examples, even more CK examples.
2.3. And what is inside?#
The docker images have everything you need for running CK including:
2.4. Which image is right for me?#
Let’s take a look at the image naming, for example “ck_ub20.04_rocm5.4_release”. The image specs are:
“ck” - made for running Composable Kernel
“ub20.04” - based on Ubuntu 20.04
“rocm5.4” - ROCm platform version 5.4
“release” - compiler version is release
So just pick the right image for your project dependencies and you’re all set.
2.5. DIY starts here#
If you need to customize a docker image or just can’t stop tinkering, feel free to adjust the Dockerfile for your needs.
