In sequential it runs ok but in parallel not. Greetings.

I tried something else : - creation of the matrix with MatCreateMPIAIJ - initialization - adding of the options MAT_SYMMETRIC and MAT_SYMMETRY_ETERNAL When solving in sequential CG + ICC, everything is ok. When I tried in parallel the same code the options lead to the same error : [0]PETSC ERROR: MatSetOption_MPIAIJ() line 1251 in src/mat/impls/aij/mpi/mpiaij.c [0]PETSC ERROR: No support for this operation for this object type! [0]PETSC ERROR: unknown option! [0]PETSC ERROR: MatSetOption() line 4137 in src/mat/interface/matrix.c Can MatSetOption be only used in sequential?

All these are integers, and it is complaining that the integer does not match MAT_SYMMETRIC. I will fix the error message to print the offending option, but please check the code.

I tried as said in the manual : I use MATMPIROWBS for the storage of the matrice. However I get this message : PETSC ERROR: To use incomplete Cholesky preconditioning with a MATMPIROWBS matrix you must declare it to be symmetric using the option MatSetOption(A,MAT_SYMMETRIC)! So I tried adding this option (even if in the namual it is written that it is not required). Then I obtained this message PETSC ERROR: MatSetOption_MPIRowbs() line 1411 in src/mat/impls/rowbs/mpi/mpirowbs.c PETSC ERROR: No support for this operation for this object type! PETSC ERROR: unknown option! PETSC ERROR: MatSetOption() line 4137 in src/mat/interface/matrix.c In advance thanks, Fa?za Pensez ? visiter le site BRGM sur.... http://www.brgm.fr/ *** Le contenu de cet e-mail et de ses pi?ces jointes est destin? ? l'usage exclusif du (des) destinataire(s) express?ment d?sign?(s) comme tel(s).
