Which efficiency? Uploads? Database storage? Querying?

In a conversation with Sun, it turns out that we both want to have the
ability to see partial results (e.g., running the entire Intel suite may
take many hours -- it would be good to be able to see results
more-or-less as they occur). Is there a technical issue that would
prevent submitting 1 (or small batches of) result(s) at a time?

Ok, good. So this would help with the database storage required for
test results -- many of the fields will be the same for each of the
individual tests in the intel test suite (for example).

So I guess I'm still not clear on *why* you want this. :-) Can you
specify the reasons?

Yes, that information (tcp vs. openib) is in one of the fields that we
send back (it has to be, otherwise the results are somewhat
meaningless). It's not a standalone "btl" field, though -- it's more of
a "here's the MCA parameters that were specified" field. So queries for
tcp results will probably need to search for "tcp" in the MCA parameters
field.

But this is the same issue regardless of whether we submit 1 result at a
time or all at once, right? I guess I don't see the difference for
selecting "tcp" vs. "openib" results based on whether we submit 1 result
at a time or all at once -- can you clarify? I think I must be missing
something...

If this is all possible, then -- at least in my mind -- I don't see a
reason why multiple submits vs. a single submit is *required*.
Obviously, multiple submits will take more bandwidth than a single
submit -- but I see that as an optimization that we can [and should]
work out later. Specifically: reducing the bandwidth of submits doesn't
need to be in the initial version since our primary, immediate goal is
to get this functional, running nightly tests, and sending out test
results in the morning as long as the current, unoptimized bandwidth
requirements are not too onerous on milliways.
