See http://www.chattanoogaengineersclub.org for more info.
Meeting at Doubletree Hotel downtown at Noon.
I suggest showing up at 11:30-11:45.
Sit close to the screen.
Ask good questions and applaud.
Unfortunately, I won't be there, I'll be in Alaska.
But hopefully some of you will.
If a bunch of you decide to go, let Tim Lee (email attached in CC)
know so there will be plenty of food. You can attend as a "guest" for
free and no food if you sit in the chairs along the wall.
The Chattanooga Engineers Club has been Sharing Ideas at weekly meetings
since 1924. This is an excellent example of why Chattanooga rocks!
Monday, July 1st:
“Performance Metrics and Application Experiences on a Cray CS300‐AC™
Cluster Supercomputer Equipped with Intel® Xeon Phi™
Coprocessors,” Dr. Vincent Betro, ORNL/UTK
In this talk, Dr. Betro will show the comparative performance and scaling
of Gyro on four generations of Cray supercomputers simultaneously
including the newest addition - the Cray CS300-AC™ Cluster Supercomputer
(which is currently #1 on the Green 500 list) and the Cray XC30. Dr.
Betro will also show that the recently added hybrid OpenMP/MPI
implementation shows a great deal of promise not only on traditional HPC
systems that utilize fast CPUs and proprietary interconnects but also on
coprocessor architecture in a cluster environment in native mode.
Moreover, several applications which have been ported to the Intel Xeon
Phi coprocessor will be discussed, and limitations and successes will be
explained. Four machines of varying sizes were used in the experiment,
all of which are located at the National Institute for Computational
Sciences at the University of Tennessee at Knoxville and Oak Ridge
National Laboratory. Darter is a 23,936 core Cray XC30 with Intel E5-2670
CPUs, a Dragonfly network, and a Sonexion lustre file system; Kraken is a
112,896 core Cray XT5 with AMD Opteron™ Istanbul CPUs; Ares is an 896
core Cray XE6 with AMD Opteron™ Interlagos CPUs; and Beacon is a 1,024
core Cray CS300-AC™ Cluster Supercomputer with Intel® Xeon® E5-2670
(Sandybridge) CPUs and Intel® Xeon Phi™ coprocessors. The advantages,
limitations, and performance of using each system are discussed, as well
as the direction of future optimizations.
