GPU Device 0: "Hopper" with compute capability 9.0

Using default input file [../../../../Samples/4_CUDA_Libraries/cuSolverSp_LowlevelQR/lap2D_5pt_n32.mtx]
step 1: read matrix market format
sparse matrix A is 1024 x 1024 with 3008 nonzeros, base=1
step 2: create opaque info structure
step 3: analyze qr(A) to know structure of L
step 4: workspace for qr(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| = 5.329071E-15 
(CPU) |A| = 6.000000E+00 
(CPU) |x| = 5.000000E-01 
(CPU) |b - A*x|/(|A|*|x|) = 1.776357E-15 
step 9: create opaque info structure
step 10: analyze qr(A) to know structure of L
step 11: workspace for qr(A)
GPU buffer size = 3751424 bytes
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| = 4.218847E-15 
(GPU) |b - A*x|/(|A|*|x|) = 1.406282E-15
