In this talk, we discuss our efforts to improve the performance of the kernel, while maintaining its numerical accuracy. Our experimental results demonstrate the effectiveness of our approaches.}, author = {Ichitaro Yamazaki and Jesse Barlow and Stanimire Tomov and Jakub Kurzak and Jack Dongarra} }
