SGI Achieves Top 4 out of 5 Most Efficient Supercomputers on TOP500 List* 
SGI(R) ICE(TM) X Enables Customers to Maximize Results With Reduced
Operational Costs 
MILPITAS, CA -- (Marketwired) -- 06/24/14 --  SGI (NASDAQ: SGI), the
leader in high performance computing and Big Data, today announces
that its ICE X supercomputer platform garnered 4 of the top 5 most
efficient supercomputer rankings for standard x86-based systems,
including the #1 position, as reported on the newly released TOP500
List. As reported on the latest TOP500 List, these four energy
efficient systems are Irish Centre for High-End Computing (ICHEC),
UK's Atomic Weapons Establishment (AWE), both Spruce A and Spruce B
installations, and Germany's T-Systems. The latest edition of the
bi-annual list, reporting on the world's most powerful commercially
available computer systems, highlights that SGI ICE X systems can
achieve 20 to 40+% higher performance efficiency vs. IBM, Bull, HP
and Cray systems.** 
The best-in-class efficiency of SGI ICE X as demonstrated by the
TOP500 List helps customers achieve their goals without the
performance compromise of less efficient systems. SGI customers such
as leading commercial, academic and research institutions are
continually pushing the boundaries of computational research, but
within the constraints of today's power budget realities. In a world
where the power requirements for supercomputers are becoming an
increasing burden to budgets, more efficient compute systems
translate into direct cost savings without compromise to system
requirements. This efficiency enables greater computing power with
lower operational costs. 
SGI ICE X is the world's fastest distributed memory supercomputer
built on a completely open standards platform. It offers best in
class speed, scale and efficiency coupled with ultimate flexibility
for HPC workflows. The efficiency of SGI ICE X enables greater
megaflops per watt to achieve world-class results with less power and
operational costs. As HPC (high performance computing) environments
face increased challenges to balance performance, power and space
within limited budgets, enabling greater efficiencies is an essential
system design requirement. 
"The efficiency of SGI ICE X enables our customers to achieve
industry-leading results within tight budgets, without compromising
their performance requirements," said Jorge Titinger, president and
CEO of SGI. "We recognize that power efficiency is one way to
optimize operational costs in these high-end environments, and is an
ongoing focus in the design of our systems." 
The ICE X platform is part of a complete ecosystem of HPC solutions
that include Big Data analytics, the SGI(R) UV(TM) shared memory
system and comprehensive data management solutions. For more
