[petsc-users] no protocol specified

[Bishesh Khanal]

Hello,
I installed petsc today in our new cluster environment, everything looked
fine except for several mpi related deprecated function warnings such as
below:

/data/asclepios/user/bkhanal/softwares/petsc/src/sys/objects/pname.c: In
function ‘PetscErrorCode PetscObjectName(PetscObject)’:
/data/asclepios/user/bkhanal/softwares/petsc/src/sys/objects/pname.c:128:12:
warning: ‘int MPI_Attr_get(MPI_Comm, int, void*, int*)’ is deprecated
(declared at /opt/openmpi/gcc/current/include/mpi.h:1227): MPI_Attr_get is
superseded by MPI_Comm_get_attr in MPI-2.0 [-Wdeprecated-declarations]
     ierr =
MPI_Attr_get(obj->comm,Petsc_Counter_keyval,(void*)&counter,&flg);CHKERRQ(ierr);


When I ran make test after installation, I got the following results:

=========================================

I also tested one of my codes with  this new setup. It seems to give me
correct results but the output also displays No protocol specified (twice).

Is this a mere warning or should I worry about it ?

Thanks,
Bishesh
