%description
rocWMMA is a C++ library for accelerating mixed-precision matrix
multiply-accumulate (MMA) operations leveraging AMD GPU hardware.
rocWMMA makes it easier to break down MMA problems into fragments
and distribute block-wise MMA operations in parallel across GPU
wavefronts. Our API consists of a header library, that you can
use to compile MMA acceleration directly into GPU kernel device
code. This can benefit from compiler optimization in the
generation of kernel assembly, and doesn't incur additional
overhead costs of linking to external runtime libraries or having
to launch separate kernels.
