PRAXO-CORE OpenCL Sample

OpenCL is a compute API, not an independent contract implementation. This sample reuses the C Core's JSON parser and runs a trivial OpenCL kernel, showing one way to host GPU/compute work alongside a PRAXO-CORE tool implementation. It does not implement an agent loop, wire codec, or provider adapter.

Build and run

Install OpenCL headers, an ICD loader, and a device. On Debian/Ubuntu:

sudo apt-get install -y ocl-icd-opencl-dev pocl-opencl-icd
cc -std=c11 -DCL_TARGET_OPENCL_VERSION=300 \
  -I language/c/include -I language/c/src \
  examples/opencl/sample.c language/c/src/json.c \
  -lOpenCL -lm -o build/opencl-sample
./build/opencl-sample

POCL provides a CPU device when no GPU ICD is installed. CI uses the same packages and command.

Usage

The sample parses a PRAXO tool-call JSON value with px_parse and runs an OpenCL kernel that adds one to each element. A real integration would dispatch compute work from a tool callback and return the result as JSON; OpenCL itself does not implement the PRAXO-CORE contract.

Release

No separate tag. The sample reuses the C package c/v0.2.0.
