About the performance in different matrix layouts #553

Closed diverger closed 4 months ago

diverger commented 4 months ago

I'm porting a project based on cuBlas to clblast. As known, the former assumes all matrices are column majored. But the latter has row major as the default layout in the C++ API. Does it means it will perform better with row major matrices?

No, not necessarily. This will differ per device. You can run the included 'clients' to do benchmarks if you want.
