1, does petsc support multiple threads, if I compiled libpetsc.a with -with-mpi=0?
2, is the following usage right?
While(1)
{
         ReceiveJobfromServer();
         PetscInitialize();  //to avoid a SIGTERM error, I move the call of PetscInitialize into the loop.
         handleJob();
         PetscFinalize();
}

Thanks,
Debao

DA,

Do you happen to know what may cause this error?
         "[0]PETSC ERROR: PetscFinalize() line 968 in src/sys/objects/pinit.c"

After reporting this error, the job can run continued, but it will aborted when encountering next petsc related features even with calling PetscInitialize() again, and say:
         "Options have not been enabled.
         You might have forgotten to call PetscInitialize()."

Here is line 968:
         ierr = MPI_Finalize();CHKERRQ(ierr);

Thanks,
Debao
