widely known method for efficient computation of sparse matrices. It has been mainly applied to SpMV operations. ICCG is used for solving linear equations with sparse matrices in a wide range of applications of science and engineering. Because ICCG includes operations with data-dependency, such as forward / backward substitutions, and incomplete Cholesky factorization, extraction of parallelism by reordering is needed. The present work is the first example, where SELL-C-σ storage format is applied to ICCG.
