As I know OpenSHMEM is an effort to create a standardized SHMEM library
for C and Fortran. SGI’s SHMEM API is the baseline for OpenSHMEM
Specification 1.0.
Most of OpenSHMEM API functions can be found in different SHMEM API
implementations but there are functions that are specific for SGI`s,
Cray`s etc products.
SIte www.shmem.org says that "The SHMEM™ Application Programming
Interface (API) definition and the SHMEM trademark are the property of
SGI. "

Is there naming convention related configure options in OMPI?
Do you see any objections about --enable-oshmem-xxx or they must be replaced
with --enable-shmem-xxx?
Hmm. Good question.
I don't know enough about shmem vs. open shmem to say. Is the API the same?
If the API is the same, then you make a good point -- perhaps we should replace
all --with-oshmem-xxx and --enable-oshmem-xxx with --with-shmem-xxx and
--enable-shmem-xxx, respectively.
Supporting this view, we have several --with-mpi-xxx switches (i.e., we don't
have --with-ompi-xxx switches). But this works because Open MPI is just an
implementation of MPI. Forgive my shmem ignorance: is the oshmem/ layer an
implementation of Shmem? Or an implementation of Open Shmem? (is there a
difference between the two?)
