An Effective Implementation of LDLT Decomposition of Sparse Symmetric Matrix on GPU
Chen Xinfeng,Wang Wu
算法4. 并行化的LDLT数值分解
1: for level = 1 to nlevel do 2: //分层划分级别的并行 3: for 当前level包含的所有列 do 4: 并行分解当前的列 5: end for 6: for 当前level的所有列 do 7: //并行更新子列 8: for 依赖当前列的所有子列do 9: //并行向量MAD操作 10: 并行更新一个子列 11: end for 12: end for 13: end for
