Hey, this code reproduces the error when run with 2 or more ranks. #include #include int main(int argc, char *argv[]) { PetscInitialize(, , "", NULL); Mat matrix; MatCreate(PETSC_COMM_WORLD, ); MatSetType(matrix, MATSBAIJ); MatSetSizes(matrix, 10, 10, PETSC_DETERMINE,

Florian: Would it work if replacing MATSBAIJ to MATAIJ or MATMPISBAIJ? Hong Hey, > > this code reproduces the error when run with 2 or more ranks. > > #include > #include > > int main(int argc, char *argv[]) > { > PetscInitialize(, , "", NULL); > > Mat matrix; >
