Development of an international matrix-solver prediction system on a French-Japanese international grid computing environment

Suzuki, Yoshio; Kushida, Noriyuki; Tatekawa, Takayuki; Teshima, Naoya; Caniou, Y.*; Guivarch, R.*; Dayde, M.*; Ramet, P.*

The "Research and Development of International Matrix-Solver Prediction System (REDIMPS)" project, which is founded by the Strategic Japanese-French Cooperative Program on "Information and Communications Technology including Computer Science" with CNRS and JST, aims at improving the "Test for Large System of Equations (TLSE)" sparse linear algebra expert system by establishing an international grid computing environment between Japan and France. Here, we have established the interoperable environment between French and Japanese grid middleware (DIET and AEGIS), and have confirmed that TLSE can rely on this French and Japanese interoperable environment for researchers to select a matrix-solver suitable to their each application program. By this study, we proposed to the French and Japanese researchers the environment in which they can obtain useful information for the improvement of their application program.

Toward an international sparse linear algebra expert system by interconnecting the ITBL Computational Grid with the Grid-TLSE platform

Kushida, Noriyuki; Suzuki, Yoshio; Teshima, Naoya; Nakajima, Norihiro; Caniou, Y.*; Dayd$'e$, M.*; Ramet, P.*

Proceedings of 8th International Meeting on High Performance Computing for Computational Science (VECPAR '08) (CD-ROM), p.424 - 429, 2008/06

In the present paper, the methodology of interoperability between ITBL and Grid-TLSE is described. Grid-TLSE is an expert website to provides user assistance in choosing the right solver for its problems and appropriate values for the control parameters of the selected solve. The time to solution of linear equation solver strongly depends on the type of problem, the selected algorithm, its implementation and the target computer architecture. Grid-TLSE uses the Diet middle ware to distribute computing tasks over the Grid. Therefore, extending the variety of computer architecture by Grid middle ware interoperability between Diet and ITBL has a beneficial impact to the expert system. To show the feasibility of the methodology, job transfering program as a special service of Diet was developed.
