Accelerating the SVD bi-diagonalization of a batch of small matrices using GPUs

•A batched BLAS design based on device function and big-tile setting was proposed on the GPU.•The batched BLAS approach is used to optimize solving the batched bi-diagonalization problem.•For the first time, batched BLAS in HIP code on AMD platform was presented and compared against NVIDIA CUDA plat...
