Start with src/opencl/common.cpp at OpenCLEnv:438 and reproduce ./megpeak -d opencl, comparing its platform discovery with the provided clinfo output. Check the OpenCL initialization path and error handling around clGetPlatformIDs. Done means MegPeak recognizes the NVIDIA OpenCL platform without reporting CL_INVALID_PLATFORM.
