Dave Olien has agreed to send us his patch ported to 2.4.4 kernel to test
it on our netperf3 workload. I will be posting
the results to lse-tech. Right now my netperf3 (updated version) workload
stresses tcp streaming using 4 adapters on both the server (4-way) and the
Linux Technology Center - Performance

Subject: [Lse-tech] Minutes from 9/7 Con Call
Thank you everyone for calling in it was a good opportunity
to communicate. There were about 20 people. Mainly from
OSDL, SGI, Intel, and IBM. I tried to get everyone's name so
I am sorry if I missed you:
Tim Witham, Nathan ?, Gerrit Huizenga, Paul Jackson, Mathew Barnes,
John Hawkes, Richard Griffith, Steve Carbonari, Terry Prickett, Bill
Peter Wong, Jonathan Lahr, Hans Tannenberger, Hanna Linder,
Ruth Forester, Dave Olien, Pat Gaughen, Jack Vogel, Paul McKenney
A brief summary:
I. Tim Witham from the Open Source Development Lab
presented their new Scalable Test Platform. It looks like it is going to be
a great tool. You can check your patches into their CVS tree and
pick the tests and machines to run them on then get email
with the results (I think that is how it works). Check out the web
use login guest password guest to look around and see what they
have available. They also have a sourceforge project at:
II. Jonathan Lahr talked about his io_request_lock patch and
some performance results should come out soon.
III. Dave Olien described his I/O APIC routing patch for IA 32
systems. He assigns priorities to processes then routes interrupts
to the lower priority processes. He will backport the patch from
2.4.9 to 2.4.4. and 2.4.6 for groups in IBM and Intel to apply to some
of their test machines.
IV. A bit of benchmarking and test results talk with some coordination
of which patches to test on which systems.
V. Discussion of where to go after finishing current projects (ie-
which locks are next in line of high contention).
Next call Friday September 21st. Please send agenda items to the
list or hlinder@... by the 20th.
