We propose a general application programming interface called OpenATLib for auto-tuning (AT). OpenATLib is carefully designed to establish the reusability of AT functions for sparse iterative solvers. Using APIs of OpenATLib, we develop a fully auto-tuned sparse iterative solver called Xabclib. Xabclib has several novel runtime AT functions. We also develop(More)
We are developing ppOpen-AT, which is an infrastructureof auto-tuning (AT) for ppOpen-HPC. ppOpen-HPC is numerical middleware for post Petascale era. In this study, we propose a new auto-tuning (AT) facility for semi-structured grids in OpenFOAM. We focus on sparse matrix-vector multiplication and the matrix storage formats. Using the features of input data(More)
