An Auto-tuning Method for Run-time Data Transformation for Sparse Matrix-Vector Multiplication
Takahiro Katagiri, Masahiko Sato
In this paper, we research the run-time sparse matrix data transformation from Compressed Row Storage (CRS) to Coordinate (COO) storage and an ELL (ELLPACK/ITPACK) format with Open…

A Communication Avoiding and Reducing Algorithm for Symmetric Eigenproblem for Very Small Matrices
Takahiro Katagiri, Jun'ichi Iwata, Kazuyuki Uchida
In this paper, a parallel symmetric eigensolver with very small matrices in massively parallel processing is considered. We define very small matrices that fit the sizes of caches…
