https://docs.nvidia.com/deploy/driver-persistence/index.html I usually use "nvidia-smi -i <target gpu> -pm ENABLED" to force the driver to be loaded permanently. As for `__nvcc_device_query`, my guess is that it just uses a handful of driver API calls. Nothing unusual, it's probably the standard sequence of cuInit/cuDeviceGetCount/cuDeviceGetAttribute like in this example: https://github.com/NVIDIA/cuda-samples/blob/5f97d7d0dff880bc6567faa4c5e62e389a6d6999/Samples/1_Utilities/deviceQueryDrv/deviceQueryDrv.cpp#L56 ``` checkCudaErrors(cuInit(0)); checkCudaErrors(cuDeviceGetCount(&deviceCount)); for (dev = 0; dev < deviceCount; ++dev) { checkCudaErrors(cuDeviceGetName(deviceName, 256, dev)); ... } ``` https://github.com/llvm/llvm-project/pull/94751 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
