Hello, solved the 64-32-bit-issue, i have working now MUMPS and gain reasonable results, but I'm wondering if I could see some performance increasing by using the symmetry of the matrix. By setting only the option -mat_mumps_sym I don't see any changes in runtime and INFOG(8) returns 100.
Setting MatSetOption(A,MAT_SYMMETRIC,PETSC_TRUE) I don't see any changes either. Does MUMPS recognize and use automatically the symmetry? Cheers, ando -- /"\ Grassl Andreas \ / ASCII Ribbon Campaign Uni Innsbruck Institut f.
