Ok but the error does not come from parallell ICC. It's from the MatSetOption().
Moreover, when I tried with MATMPIROWBS , it's the same problem : [0]PETSC ERROR: MatSetOption_MPIRowbs() line 1411 in src/mat/impls/rowbs/mpi/mpirowbs.c [0]PETSC ERROR: No support for this operation for this object type! [0]PETSC ERROR: unknown option!

AIJ matrix does not support parallell ICC. BlockSolve provides parallel ICC - and to use it one must use MatType MATMPIROWBS Satish On Tue, 16 May 2006, Boulahya Fa?za wrote: > Is there something new about it? > De : Vaz, Guilherme [mailto:G.Vaz at marin.nl] > I have exactly the same problem as Faiza... > In sequential it runs ok but in parallel not. > -----Original Message----- > From: owner-petsc-users at mcs.anl.gov > [mailto:owner-petsc-users at mcs.anl.gov] > On Behalf Of Boulahya Fa?za > 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.
