INTRODUCTION TO ROADRUNNER,SUPER COMPUTER
Roadrunner was a supercomputer built by IBM for the Los Alamos National Laboratory in New Mexico, USA. The US$100-million Roadrunner was designed for a peak performance of 1.7 petaflops.It achieved 1.026 petaflops on May 25, 2008 to become the world's first TOP500 Line pack sustained 1.0 petaflops system.

WHAT IS ROADRUNNER
• Roadrunner is the first general purpose computer system to reach the petaflop milestone. On June 10, 2008, IBM announced that this supercomputer had sustained a record-breaking petaflop, or 1015 floating point operations per second, as measured by the Line pack benchmark. As a result of this achievement, Roadrunner became the world’s fastest supercomputer.

WHO WAS THE INVENTOR
• International Business Machines (IBM) built the Roadrunner Not only did they make the Roadrunner, they also built the Blue Gene They pioneer in computer technology, the Roadrunner is the fastest supercomputer in the world breaking the petaflop barrier at 1.7 petaflops (1,700 trillion calculations per second.)

PURPOSE AND IMPORTANCE OF THIS INVENTION
• IBM built the Roadrunner for the U.S. Department of Energy (DOE) National Nuclear Security Administration.
• The DOE plans to use this computer for simulating how nuclear materials age in order to predict whether the USA’s aging arsenal of nuclear weapons are safe and reliable.
• Other uses for the Roadrunner include science, financial, automotive, and aerospace industries.

WHERE DID IBM INVENT THE ROADRUNNER
• IBM built the Roadrunner at Los Alamos National Laboratory in New Mexico, USA.
• The Roadrunner consists of 296 refrigerator-sized racks that occupies 6,000 sq. ft. of the laboratory (560 sq. km.)

WHEN WAS THE ROADRUNNER INVENTED
• WHEN WAS THE ROADRUNNER INVENTED• The Roadrunner was invented and developed from late December 2007 to April 2009.
• Test day was on May 25, 2008 when the Roadrunner achieved a top performance of 1.026 petaflops.

DEVELOPMENT OF ROADRUNNER •
• Roadrunner was in development from 2002 and went online in 2006. Due to its novel design and complexity it was constructed in three phases and became fully operational in 2008. Its predecessor was a machine also developed at Los Alamos named Dark Horse. This machine was one of the earliest hybrid architecture systems originally based on ARM and then moved to the Cell processor. It was entirely a 3D design, its design integrated 3D memory, networking, processors and a number of other technologies
• Phase 1: Build the opteron based cluster.• Phase 2: Advance architecture Initial System,to include a smaller version
of the hybrid usin older versions of the Cell processor.• Phase 3: To reach 1 petaflops.•

ROADRUNNER CLUSTER• The final cluster is made up of 18 connected units,
which are connected via eight additional (second-stage) Infiniband ISR2012 switches. Each CU is connected through twelve uplinks for each second-stage switch, which makes a total of 96 uplink connections.
• Overall system information:• 6,480 Opteron processors with 51.8 TIB RAM (in 3,240
LS21 blades)• 12,960 Cell processors with 51.8 TIB RAM (in 6,480
QS22 blades)• 216 System x3755 I/O nodes

ROADRUNNER SOFTWARE
• The Roadrunner runs on Red Hat Enterprise Linux along with Fedora 10 Linux as its operating systems.
• It is managed with XCAT distributed computing software.
• It also uses Open MPI Message Passage Interface implementation
