that the application needs to be linked with libopa as well. In
general, it is good to use pkg-config to see what all libraries are
required and link with all of them.

For the inter-library dependencies, I'd not like to have a Debian-only

Feel free to ignore this, but at some point this will become a

The best method is to use pkg-config to find what libraries need to be

Note that this is not portable, so there'll need to be a configure
option to enable it for platforms that libtool supports it on.
Or did you mean something else?

a requirement of binutils-gold.

--with-device=ch3:sock), which doesn't use shared memory at all and
hence doesn't need OPA atomics.
3. You can contribute m68k processor atomics to OPA, so it is natively
supported and OPA doesn't have to fall back to locks.

But that working group fizzled out. I'll check on what exactly happened
with it in the next meeting (in May). Even if the MPI standard

MPICH2 and Open MPI do whatever the ABI working group was proposing
outside of the standard, which might be sufficient for you guys.

hurt performance a little, but might be a lot more manageable. Let me

We had a short discussion on this within the MPICH group. We believe
that we will be able to modify the code such that enabling it at
configure time should not add any additional performance overhead for
applications that don't need this support. So starting mpich2-1.3, you
should be
