. In this paper, we describe an auto-tuning methodology for the parallel tridiagonalization to attain high performance. By searching the optimal set of three parameters for the performance, a highly...
Performance of Automatically Tuned Parallel GMRES(m) Method on Distributed Memory Machines (2000)
Hisayasu Kuroda, Takahiro Katagiri, Yasumasa Kanada
. As far as the presently available public parallel libraries are concerned, users have to set parameters, such as a selection of algorithms, an unrolling level, and a method of communication. These...
