isCudaAvailable

Fully qualified name: usd_optimize::isCudaAvailable

bool usd_optimize::isCudaAvailable()

Check if a CUDA-capable GPU is available.

This function checks if there is at least one CUDA-capable GPU available on the system by loading the CUDA driver library and querying for devices. The result is cached after the first call for efficiency. Thread-safe.

NOTE: This function is defined in CudaUtils.cpp and lives in the core plugin shared library so that the static state (once_flag + cached result) is shared across all operation plugins. A header-only definition would give each plugin .so its own copy of the statics, defeating the call_once caching.

Returns:

true if a CUDA GPU is available, false otherwise
