IBM Wows with Blue Gene/P Supercomputer

IBM unveils Blue Gene/P, the second generation of the most powerful supercomputer in the world. Blue Gene/P nearly triples the performance of its predecessor, Blue Gene/L while remaining the most energy-efficient and space-saving computing package ever built. The result is a machine that towers over other systems. It enables science and commercial supercomputing to attack vital problems in ways never before possible - modeling an entire human organ to determine drug interactions, for example. Drug researchers could run simulated clinical trials on 27 million patients in one afternoon using just a sliver of the machine's full power.

The IBM System Blue Gene/P Solution scales to operate continuously at speeds exceeding one "petaflop" - or one-quadrillion operations per second. The system is 100,000 times more powerful than a home PC and can process more operations in one second than the combined power of a stack of laptop computers nearly 1.5 miles high. The Blue Gene/P supercomputer can be configured to reach speeds in excess of three petaflops, a performance level that many thought unattainable only a few short years ago.

The Blue Gene supercomputer line was born from a visionary IBM initiative to develop a hugely scalable and highly reliable scientific computing platform. With Blue Gene, designers sidestepped two key constraints on state-of-the-art supercomputing - power usage and space requirements. The Blue Gene supercomputer was purpose-built to fit in smaller spaces and use less electricity compared to other commercially available designs. Today, the Blue Gene/P supercomputer is at least seven times more energy efficient than any other supercomputer.

The influence of the Blue Gene supercomputer's energy-efficient design and computing model - once considered exotic - can be seen everywhere in the industry where people have attempted to lower energy use and get performance without traditional reliance on chip frequency. The BlueGene supercomputer design uses many small, low-power embedded chips each connected through five specialized networks inside the system.

Like its predecessor, the Blue Gene/P supercomputer is a modular design, composed of "racks" that can be added as requirements grow. Four IBM (850 MHz) PowerPC 450 processors are integrated on a single Blue Gene/P chip. Each chip is capable of 13.6 billion operations per second. A two-foot-by-two-foot board containing 32 of these chips churns out 435 billion operations every second, making it more powerful than a typical, 40-node cluster based on two-core commodity processors. Thirty-two of the compact boards comprise the 6-foot-high racks. Each rack runs at 13.9 trillion operations per second, 1,300 times faster than today's fastest home PC.

The one-petaflop Blue Gene/P supercomputer configuration is a 294, 912-processor, 72-rack system harnessed to a high-speed, optical network. The Blue Gene/P system can be scaled to an 884,736-processor, 216-rack cluster to achieve three-petaflop performance. A standard Blue Gene/P supercomputer configuration will house 4,096 processors per rack.

There are some key differences between Blue Gene/L and Blue Gene/P supercomputers. In hardware, the Blue Gene/P supercomputer moves to more (four vs two) and speedier (850 MHz vs 700 MHz) processors per chip; more memory and an SMP mode to support multi-threaded applications. This new SMP mode moves the Blue Gene/P system to a programming environment similar to that found in commercial clusters. The Blue Gene/P supercomputer dramatically scales up collective network performance to minimize common bottlenecks inherent in large parallel-computing systems. Software marks the third key upgrade for the Blue Gene/P solution - system management, programming environment and applications support have all been refined in Blue Gene/P.

The Blue Gene supercomputer operating system is based on the open-source Linux operating system. Applications are written in common languages such as Fortran, C and C++ using standards-based MPI communications protocols. The Blue Gene/P supercomputer is compatible with the diverse applications currently running on the Blue Gene/L supercomputer, including leading research in physics, chemistry, biology, aerospace, astrophysics, genetics, materials science, cosmology and seismology.

A variety of independent software vendors have plans to port existing tools and applications to the Blue Gene/P supercomputer. These include Gene Network Sciences, TotalView Technologies, Tsunami Development and Visual Numerics.
