MIVisionX environment variables

The following environment variables control the runtime behavior of MIVisionX.

Core OpenVX configuration

Environment variable	Values
AGO_DEFAULT_TARGET Sets the default execution target for OpenVX kernels.	"GPU": execute kernels on the GPU "CPU": execute kernels on the CPU Unset: use the library default
AGO_BUFFER_MERGE_FLAGS Controls buffer-merging optimization.	Integer bitmask 0: disable buffer merging Higher values enable more aggressive merging
AGO_THREAD_CONFIG Configures the number of CPU threads used for graph execution.	0: use the default thread count Positive integer: use that many threads
VX_GRAPH_ATTRIBUTE_AMD_OPTIMIZER_FLAGS Sets graph optimizer flags for AMD extensions.	Integer bitmask 0: disable optimizations Positive values enable specific optimizations

GPU and device configuration

Environment variable	Values
GPU_ENABLE_WGP_MODE Controls Workgroup Processor (WGP) mode on RDNA GPUs that support both CU and WGP modes (GPU major version ≥ 10).	0: use CU mode 1 (or any non-zero): use WGP mode (default)

OpenCL configuration

Environment variable	Values
AGO_OPENCL_PLATFORM Overrides the default OpenCL platform selection.	String — name of the OpenCL platform to use
AGO_OPENCL_VERSION_CHECK Controls OpenCL version checking.	String — set to disable or relax version validation
AGO_OPENCL_BUILD_OPTIONS Appends options to the OpenCL kernel compiler invocation.	String — valid OpenCL compiler flags
AGO_OPENCL_DEVICE_INFO Controls OpenCL device information reporting (useful for debugging).	String — controls the verbosity of device info output

Debugging and profiling

Environment variable	Values
AGO_DUMP_GPU Dumps compiled GPU kernel source to disk for inspection.	Set to any non-empty string to enable
