|
Using default input file [../../../../Samples/4_CUDA_Libraries/cuSolverSp_LowlevelCholesky/lap2D_5pt_n100.mtx]
|
|
step 1: read matrix market format
|
|
sparse matrix A is 10000 x 10000 with 49600 nonzeros, base=1
|
|
step 2: create opaque info structure
|
|
step 3: analyze chol(A) to know structure of L
|
|
step 4: workspace for chol(A)
|
|
step 5: compute A = L*L^T
|
|
step 6: check if the matrix is singular
|
|
step 7: solve A*x = b
|
|
step 8: evaluate residual r = b - A*x (result on CPU)
|
|
(CPU) |b - A*x| = 3.637979E-12
|
|
(CPU) |A| = 8.000000E+00
|
|
(CPU) |x| = 7.513384E+02
|
|
(CPU) |b - A*x|/(|A|*|x|) = 6.052497E-16
|
|
step 9: create opaque info structure
|
|
step 10: analyze chol(A) to know structure of L
|
|
step 11: workspace for chol(A)
|
|
step 12: compute A = L*L^T
|
|
step 13: check if the matrix is singular
|
|
step 14: solve A*x = b
|
|
(GPU) |b - A*x| = 1.477929E-12
|
|
(GPU) |b - A*x|/(|A|*|x|) = 2.458827E-16
