    • cuThomasBatch and cuThomasVBatch, CUDA Routines to compute batch of tridiagonal systems on NVIDIA GPUs 

      Valero Lara, Pedro; Martinez Pérez, Ivan; Sirvent, Raül; Martorell Bofill, Xavier; Peña, Antonio J. (Wiley, 2018-01-01)
      Article
      Open Access
      The solving of tridiagonal systems is one of the most computationally expensive parts in many applications, so that multiple studies have explored the use of NVIDIA GPUs to accelerate such computation. However, these studies ...
