3// The default layout should be column. 
4// This test is disabled because `gfx` layer always initializes Slang to use row-major layout.
5// To test this behavior we need to find a way to make `gfx` use Slang default instead.
6// Unfortunately CPU and CUDA only work with row layout, so they have to be disabled here.
