Results
A unified triangular solver for ILU-like preconditioners is developed. A new matrix format and the corresponding parallel algorithm are designed. Based on this triangular solver, block ILU(0), block ILUT and domain decomposition preconditioners are implemented. Numerical experiments show that these GPU based parallel preconditioners are around 8 times faster than our CPU based preconditioners.
