CUBLASSTATUSINVALIDVALUE

CUBLASSTATUSINVALIDVALUE is an enumeration value defined within the CUBLAS library, a collection of Basic Linear Algebra Subprograms (BLAS) specifically optimized for NVIDIA GPUs. This status code indicates that one or more of the input arguments provided to a CUBLAS function were invalid. The specific nature of the invalid value can vary depending on the function being called, but it generally pertains to incorrect dimensions, out-of-bounds pointers, or other parameter misconfigurations that prevent the operation from proceeding.

When a CUBLAS function returns CUBLASSTATUSINVALIDVALUE, it signifies that the library could not execute the requested computation due to a problem with the data or parameters passed to it. This is a critical error that requires the calling application to identify and correct the offending argument(s). Common causes include passing null pointers where valid memory addresses are expected, specifying zero or negative dimensions for matrices or vectors, or providing data that does not meet the requirements of the specific BLAS routine. Developers encountering this error should consult the CUBLAS API documentation for the function in question to understand the valid range and types of parameters. Reviewing the arguments passed to the function, especially those related to data sizes and memory locations, is essential for debugging.
