Error Handling
oneMKL error handling relies on the mechanism of C++ exceptions. Should errors occur, they are propagated at the point of a function call where they are caught using standard C++ error handling mechanisms.
Exception Classification
Exception classification in oneMKL is aligned with C++ Standard Library classification. oneMKL introduces a class that defines the base class in the hierarchy of oneMKL exception classes. All oneMKL routines throw exceptions inherited from this base class.
In the hierarchy of oneMKL exceptions, oneapi::mkl::exception is the base class inherited from the std::exception class. All other oneMKL exception classes are derived from this base class.
All oneMKL problem-specific exceptions are listed in the following table.
Exception Class |
Description |
---|---|
oneapi::mkl::unsupported_device |
Reports a problem when the routine is not supported on a specific device |
oneapi::mkl::host_bad_alloc |
Reports a problem that occurred during memory allocation on the host |
oneapi::mkl::device_bad_alloc |
Reports a problem that occurred during memory allocation on a specific device |
oneapi::mkl::unimplemented |
Reports a problem when a specific routine has not been implemented for the specified parameters |
oneapi::mkl::invalid_argument |
Reports problem when arguments to the routine were rejected |
oneapi::mkl::uninitialized |
Reports problem when a handle (descriptor) has not been initialized |
oneapi::mkl::computation_error |
Reports any computation error that occurred inside the oneMKL routine |
oneapi::mkl::batch_error |
Reports errors that occurred inside batch oneMKL routines |
