Well, I am by no means an expert on the GNU-style asm directives. I
believe someone else (George Bosilca?) tweaked what I had suggested.
That being said, I think the memory "clobber" is harmless.

Let's say I have an MPI application that runs on several hosts. I

Yes.
and the MPI communication correctly sends the data?
I'm not sure what you're asking, but the code looks as though it ought
to work.

Sorry, I don't have an answer about performance.
You may need to ask somebody else or google around
about the relative performance of 32-bit vs. 64-bit mode.
It is worth trying 64-bit. The performance is going to depend on the
program. Since 6

Typo. That should be --disable-mpi-threads.
