From November, produced at the Texas Advanced Super Computing Center
(TACC ) in Austin, a new data center that will house from 2013 to the
10-petaflop supercomputer Stampede. Main partners Dell and Intel, Dell
produces several thousands of "Zeus" servers, each with two 8-core Xeons
coming of E5 series (Sandy Bridge-EP) and 32 GB of RAM. The CPU-cores
together provide PFlops 2. The remaining 8 PFlops bring "Knights Corner
]" plug-in cards: This incarnation of the Integrated Many-cores (MIC -)
architecture from Intel is a development of the Larrabee, Intel is
working on since 2006. Intel currently delivers the precursor Knights
Corner Knights Ferry from some developers.
Stampede will also have 128 Nvidia graphics cards, but will not work as
co-processors, GPGPU, so to speak, but take on classic tasks in the
visualization of data. For the data analysis will also get Stampede 16
additional nodes, each with 1 TB of main memory and two GPUs. Overall,
the system 272 TB of main memory and 14 petabytes include mass storage.
All compute nodes are to each other with Infiniband FDR at 56 Gb / s
communication.
The TACC is expecting investments worth 50 million U.S. dollars over
four years. The option to upgrade again Stampede in 2017, was also
agreed. Stampede is part of the XD-project of the National Science
Foundation (NSF) of USA.
At the TACC since 2008 is also Ranger, who took 4th place at that time
in the Top500 list, and currently is ranked 17 . Ranger consists of
blade servers from Sun and is equipped with quad-core Opterons from AMD.
