cuBLAS works with 11.2, but not with 11.3 on RTX 3080 Mobile. On A100 both work

Hello developers-community,

I use the following cubLASS call:

    c = cublasGemmEx(cublas,
        cublasOperation_t::CUBLAS_OP_N,
        cublasOperation_t::CUBLAS_OP_N,
        src_h,
        src_w,
        src_w,
        &alpha,
        dev_x,
        cublasDataType_t::CUDA_R_16F,
        src_w,
        dev_y,
        cublasDataType_t::CUDA_R_16F,
        src_w,
        &beta,
        dev_z,
        cublasDataType_t::CUDA_R_16F,
        src_w,
        cublasComputeType_t::CUBLAS_COMPUTE_16F,
        cublasGemmAlgo_t::CUBLAS_GEMM_DEFAULT);

on RTX 3080 Mobile with cuda 11.2 it works perfectly, but on 11.3 it returns following error.

On entry to GEMM_EX parameter number 9 had an illegal value

All input matrices are half and CUDA_R_16F is valid.

The same code runs perfectly on A100 with 11.3

Why RTX 3080 doesn’t work with 11.3 and cublass?

Thank you!

Do you mind providing an complete example we can run?
