Flux-Vector-Splitting (FVS) method for Z4 formalism and its numerical analysis (2008)
Yano, Ryosuke, Suzuki, Kojiro, Kuroda, Hisayasu
The previously developed Flux-Vector-Splitting (FVS) method was formulated here for the first-order version of Z4 formalism. Then, the characteristics of this method formulated for Z4 formalism were...

. 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...
Performance of Automatically Tuned Parallel GMRES(m) Method on Distributed Memory Machines (2000)
Hisayasu Kuroda, Takahiro Katagiri, Yasumasa Kanada
this paper, we focussed on the GMRES(m) which is improved GMRES(Generalized Minimal RESidual method) and developed the library for it on distributed memory machines.
