iohann.s.titov@gmail.com Ivan S. Titov hipTensor is AMD's tensor primitives library, covering contraction, reduction and permutation of arbitrary-rank tensors through an einsum-style descriptor API. It is the ROCm counterpart to NVIDIA's cuTENSOR and is implemented on top of the contraction, reduction and elementwise kernel instances that sci-libs/composable-kernel generates, so it requires that package to be built with USE=hiptensor.
