Khai : Your solution components have values ranging from 1.e+9 to 1.e-8, and the values only differ in the order of 1.e-8, which are within computational error tolerance. I would consider all solutions same within the approximation tolerance.
Hong Hello, > > I have problem with matrix assembly for linear solver KSP. I run the the > same problem with 4 processors multiple time. Using flag > -mat_view ::ascii_matlab to view the matrix. The matrix outputs are not the > same during each run. Please see the attached file for the comparison > between two runs. I checked all the input for each processor as it calls to > MatSetValues ( indices of the matrix and values ) and it's consistent all > the time. I also checked the allocation information (with flag -info) and > it looks fine. Could you give me an advice how to deal with this issue? > Thanks ! > > Best, > Khai >
