CI

In addition to Github Actions whisper.cpp uses a custom CI framework:

https://github.com/ggml-org/ci

It monitors the master branch for new commits and runs the ci/run.sh script on dedicated cloud instances. This allows us to execute heavier workloads compared to just using Github Actions. Also with time, the cloud instances will be scaled to cover various hardware architectures, including GPU and Apple Silicon instances.

Collaborators can optionally trigger the CI run by adding the ggml-ci keyword to their commit message. Only the branches of this repo are monitored for this keyword.

It is a good practice, before publishing changes to execute the full CI locally on your machine:

mkdir tmp

# CPU-only build
bash ./ci/run.sh ./tmp/results ./tmp/mnt

# with CUDA support
GG_BUILD_CUDA=1 bash ./ci/run.sh ./tmp/results ./tmp/mnt

Environment Variables

The CI script supports several environment variables to control the build:

Variable	Description
GG_BUILD_CUDA	Enable NVIDIA CUDA GPU acceleration
GG_BUILD_SYCL	Enable Intel SYCL acceleration
GG_BUILD_VULKAN	Enable Vulkan GPU acceleration
GG_BUILD_METAL	Enable Metal acceleration on Apple Silicon
GG_BUILD_BLAS	Enable BLAS CPU acceleration
GG_BUILD_OPENVINO	Enable OpenVINO support
GG_BUILD_COREML	Enable Core ML support for Apple Neural Engine
GG_BUILD_LOW_PERF	Limit tests for low-performance hardware
GG_BUILD_TEST_MODELS	Comma-separated list of models to test (e.g. "tiny.en,tiny,base,medium", defaults to all models unless GG_BUILD_LOW_PERF is set)
