Additional context

Running the program on an Intel GPU shows the error.

The CUDA and HIP programs run successfully on the NVIDIA and AMD GPUs, respectively.

Hi @jinz2014,

Indeed, not every device is required to support every possible combination of matrix data type, size and other parameters.

See the extension specification, there are both compile-time and runtime queries available to see which combinations are supported by a specific device.

In the appendix section you can also find a summary of what is supported on various Intel GPUs.

I think this will be supported when it is supported by wmma and rocm-wmma.
