=== Lustre 2.7.0 ===

Not much news. Development underway, landings continue.

=== Contract Development Status ===

* CLIO Implementation contract is well under way. SOW more or less complete pending input from lawyers.
* Lustre Protocol Documentation contract starting up.

=== Discuss Lustre Quality Assurance Improvement ===

It was suggested that the Lustre Protocol Documentation project
and code simplification and refactoring projects would be the
place to start.

We can try to move towards stricter peer reviews.

We could have presentations and discussions about peer review expectations
at Lustre developer meetings. This segued into a discussion about having
a new Lustre developers meeting.

People expressed concern that travel budgets might not allow yet another
face-to-face meeting in addition to LUG, LAD, and SC. Is was suggested
that we can add a day (or more) onto the end of LUG just for those
involved in Lustre development.

General agreement seemed to be that we could also try to hold a new
separate developer meeting in, it was suggested, January. The rationale being
that it is somewhat after holiday season, but also well distanced in time from
LUG, LAD, and SC.

We could attempt to get people to meet face-to-face, and have video
conferencing capabilities for those who cannot meet.

We would find out if that new meeting is really going to be useful
by comparing attendance with the also proposed developer meeting adjacent
to LUG.

It was asked whether Cray would open up their testing tool as was suggested
at the working group meetings at LUG. Cory explain that it would not
be the testing tool/suite that was opened up, but perhaps some of the
individual filesystem test cases could be opened and/or they could post
explanations of what some of the test cases do. It is taking longer
than Cory had hoped.

Cory asked about whether we currently know code coverage stats for
existing tests.

Cory asked how do we formalize testing improvment? It did sound like
much was proposed in response.

Cray is looking into utilizing NRS to create delays and investigate
new failure modes.

Andreas stated that everything that people do to improve quality is good.
He suggested that there isn't going to be one thing that makes it all better.

Having quantitative measurements of quality is good idea, but can take a
great deal of time to do that. Metrics are nice in theory, but difficult
to get right. How many timeouts and evictions during testing might be
useful. Bugs per line of code really hard to quantify, and not of much value.

==== Questions relayed by Chris for conversation ====

===== Should OpenSFS have contract to fund two full time testers and part time project
manager? =====

Cory - a little uncomfortable with that idea. Current vendors already have
those resources. How would that work? Would they report to Board or what?

Andreas - Couldn't be someone random. Would have to be someone organization
already involved in Lustre. Hard to show progress.

Andreas - what do people think of code documentation project?

Folks agreed it was good. General agreement seemed to be that code
documentation should continue.

===== Should OpenSFS have a contract to fund an open source testing framework? =====

Cray - probably a good idea. nervous that we would not do it the right way

Andreas - ask if one of the existing frameworks could be open sourced
without starting a new one. Not sure if Intel would be willing to do so
or not. Not under Andreas' power to make that call.

Andreas also suggest that we had been down that path before years ago, and the
scope quickly balooned out of reasonable proportions.

Too many people and organizations with different ideas of where they want to test.

Chris - It could easily be a very big and expensive project

Andreas - Also could potentially be a reduction of heterogeneity in
our collective testing if we all adopt the same tests. If everyone running the
same thing, will we find enough bugs?

Different testing systems have different goals: Cray system about launching jobs and
monitoring results, Intel system about booting nodes and testing patches.

End of the hour reached. Participants encouraged to continue conversation on the
mailing list.
