    Invalid stream.

  enumerator CUPTI_ERROR_INVALID_KIND

    Invalid kind.

  enumerator CUPTI_ERROR_INVALID_EVENT_VALUE

  enumerator CUPTI_ERROR_HARDWARE_BUSY

    The performance monitoring hardware is in use by other client.

  enumerator CUPTI_ERROR_NOT_SUPPORTED

    The attempted operation is not supported on the current system or device.

  enumerator CUPTI_ERROR_UM_PROFILING_NOT_SUPPORTED

    Unified memory profiling is not supported on the system.

    Potential reason could be unsupported OS or architecture.

  enumerator CUPTI_ERROR_UM_PROFILING_NOT_SUPPORTED_ON_DEVICE

    Unified memory profiling is not supported on the device.

  enumerator CUPTI_ERROR_UM_PROFILING_NOT_SUPPORTED_ON_NON_P2P_DEVICES

    Unified memory profiling is not supported on a multi-GPU configuration without P2P support between any pair of devices.

  enumerator CUPTI_ERROR_UM_PROFILING_NOT_SUPPORTED_WITH_MPS

    Unified memory profiling is not supported under the Multi-Process Service (MPS) environment.

    CUDA 7.5 removes this restriction.

  enumerator CUPTI_ERROR_CDP_TRACING_NOT_SUPPORTED

    In CUDA 9.0, devices with compute capability 7.0 don’t support CDP tracing.

  enumerator CUPTI_ERROR_VIRTUALIZED_DEVICE_NOT_SUPPORTED

    Profiling on virtualized GPU is not supported.

  enumerator CUPTI_ERROR_CUDA_COMPILER_NOT_COMPATIBLE

    Profiling results might be incorrect for CUDA applications compiled with nvcc version older than 9.0 for devices with compute capability 6.0 and 6.1.

    Profiling session will continue and CUPTI will notify it using this error code. User is advised to recompile the application code with nvcc version 9.0 or later. Ignore this warning if code is already compiled with the recommended nvcc version.

  enumerator CUPTI_ERROR_INSUFFICIENT_PRIVILEGES

    User doesn’t have sufficient privileges which are required to start the profiling session.

    One possible reason for this may be that the NVIDIA driver or your system administrator may have restricted access to the NVIDIA GPU performance counters. To learn how to resolve this issue and find more information, please visit https://developer.nvidia.com/CUPTI_ERROR_INSUFFICIENT_PRIVILEGES

  enumerator CUPTI_ERROR_OLD_PROFILER_API_INITIALIZED

    Legacy CUPTI Profiling API i.e.

    event API from the header cupti_events.h and metric API from the header cupti_metrics.h are not compatible with the Profiling API in the header cupti_profiler_target.h and Perfworks metrics API in the headers nvperf_host.h and nvperf_target.h.

  enumerator CUPTI_ERROR_OPENACC_UNDEFINED_ROUTINE

    Missing definition of the OpenACC API routine in the linked OpenACC library.

    One possible reason is that OpenACC library is linked statically in the user application, which might not have the definition of all the OpenACC API routines needed for the OpenACC profiling, as compiler might ignore definitions for the functions not used in the application. This issue can be mitigated by linking the OpenACC library dynamically.

  enumerator CUPTI_ERROR_LEGACY_PROFILER_NOT_SUPPORTED

    Legacy CUPTI Profiling API i.e.

    event API from the header cupti_events.h and metric API from the header cupti_metrics.h are not supported on devices with compute capability 7.5 and higher (i.e. Turing and later GPU architectures). These APIs were deprecated in CUDA 12.8 and removed in CUDA 13.0. These are replaced by the host profiling API in the header cupti_profiler_host.h and target profiling API in the header cupti_range_profiler.h which are supported on devices with compute capability 7.5 and higher (i.e. Turing and later GPU architectures). Further, the PC Sampling Activity API and the source/SASS level metrics from the header cupti_activity.h are removed in CUDA 13.0.

  enumerator CUPTI_ERROR_MULTIPLE_SUBSCRIBERS_NOT_SUPPORTED

    CUPTI doesn’t allow multiple callback subscribers.

    Only a single subscriber can be registered at a time. Same error code is used when application is launched using NVIDIA tools like Nsight Systems, Nsight Compute, and cuda-gdb.

  enumerator CUPTI_ERROR_VIRTUALIZED_DEVICE_INSUFFICIENT_PRIVILEGES

    Profiling on virtualized GPU is not allowed by hypervisor.

  enumerator CUPTI_ERROR_CONFIDENTIAL_COMPUTING_NOT_SUPPORTED

    Profiling and tracing are not allowed when confidential computing mode is enabled.

  enumerator CUPTI_ERROR_CMP_DEVICE_NOT_SUPPORTED

    CUPTI does not support NVIDIA Crypto Mining Processors (CMP).

    For more information, please visit https://developer.nvidia.com/ERR_NVCMPGPU

  enumerator CUPTI_ERROR_MIG_DEVICE_NOT_SUPPORTED

    Profiling on Multi-instance GPU (MIG) is not supported.

  enumerator CUPTI_ERROR_SLI_DEVICE_NOT_SUPPORTED

    Profiling on SLI device is not supported.

  enumerator CUPTI_ERROR_WSL_DEVICE_NOT_SUPPORTED

    Profiling on WSL device is not supported.

  enumerator CUPTI_ERROR_INVALID_CHIP_NAME

    For invalid or unsupported chip name passed to cuptiProfilerHostInitialize.

  enumerator CUPTI_ERROR_HES_TRACE_NOT_SUPPORTED_ON_MPS

    Hardware Event System (HES) trace is not supported on MPS.

  enumerator CUPTI_ERROR_UNKNOWN

    An unknown internal error has occurred.
