Hello all,
Here are more results, where each section's heading indicates
server-client size (e.g. 32-65 is a 32-bit server and a 64-bit client),
only related to userspace; that is both machines are running (identical)
64-bit kernels. Each row is headed by the particular kernel which was
booted on the two machines (If the kernel is suffixed with svn, then it
indicates that the OpenIB kernel components were used. If not, then it
is a mainline tree without modification). The userpace (and kernel,
where applicable) svn revision is listed following the kernel version.
This e-mail is ridiculously long, but there is *a lot* of data here...
Enjoy!
FYI, all of the errors in the footnotes are from the client-side. If you
would like to see what the server-side said, please just ask.

NetPIPE: error writing or reading synchronization string: Connection reset by

This seems to be an actual error, not necessarily a programmatic one
like [1]-[3]. It seems netPIPE over IB verbs is unhappy with mixing the
size of the server client (does ok when they are the same, though).
[5]
These errors are due to our test grid, and thus are not indicative of
errors in the code.

Just like with the results I posted earlier, all the perftest results
are seriously wrong for 32-bit clients (with both 32-bit and 64-bit
servers). I am not sure who else to notify beyond the general list (is
there a corresponding MAINTAINERS files like in the kernel proper for
the OpenIB code?)
