Cray CS300-AC - Presentation - Monday

From: Mike Harrison 
------------------------------------------------------

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.



=============================================================== From: Stephen Kraus ------------------------------------------------------ Damn, I'm pissed I am going to miss this. I love supercomputing =E2=80=90AC=E2=84=A2 ng hich is so at s al Istanbul PUs; and Intel=C2=AE oprocessors. The

=============================================================== From: John Aldrich ------------------------------------------------------ Quoting Stephen Kraus : That's one of the things I miss about not working in Chattanooga... I can never g to any of these nifty lunch meetings! :(

=============================================================== From: Mike Harrison ------------------------------------------------------ Maybe a person from Chugalug attends and records it? Might be interesting. (with permission)
