Hi Jeff,

I would like to add few notes inline

These examples are not OpenSHMEM specific.

OpenSHMEM specification says
>>>
10.1 Incorporating OpenSHMEM into Programs
C and C++ programs that use the OpenSHMEM library must
#include <shmem.h>
All Fortran OpenSHMEM programs should
include ’shmem.fh’
and Fortran OpenSHMEM programs that use constants defined by OpenSHMEM must
include ’shmem.fh’
10.1.1 Compatibility Note
Implementations must also provide these header files so that they can be
referenced in C
and C++ as
#include <mpp/shmem.h>
and in Fortran as
include ’mpp/shmem.fh’
for backward compatbility with OpensHMEM 1.0 and SGI SHMEM.
