<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
All input arguments to the kernel must be passed by reference, Petsc objects are
inherrently passed by reference so you don't need to additionally & them.
<P>
Example usage - <A HREF="../PetscThreadComm/PetscThreadCommRunKernel0.html#PetscThreadCommRunKernel0">PetscThreadCommRunKernel0</A>(comm,(PetscThreadKernel)kernel_func);
with kernel_func declared as
<A HREF="../Sys/PetscErrorCode.html#PetscErrorCode">PetscErrorCode</A> kernel_func(<A HREF="../Sys/PetscInt.html#PetscInt">PetscInt</A> thread_id)
<P>
The first input argument of kernel_func, thread_id, is the thread rank. This is passed implicitly
by PETSc.
