Department of Defense Selects ibm Supercomputer for Navy to Triple Computing Power

The Department of Defense (DoD) has selected new high-performance computing (HPC) systems from IBM for deployment at the Naval Oceanographic Office (NAVOCEANO) Major Shared Resource Center (MSRC) that, when deployed, are expected to include the fastest supercomputer in the US military, and one of the fastest supercomputing clusters in the world, according to the current TOP500 List of supercomputers. The new systems are designed to triple the effective computing power of the Center, providing dramatically improved computational support for DoD research and development (R&D) and enhancement of global scale modeling and simulation capabilities for the US Navy in support of worldwide Navy and DoD operations.

The new supercomputers are designed to substantially enhance the Navy’s ability to perform global scale modeling and simulation to carry out its diverse mission, maximizing support to the Fleet worldwide and to the nation. The largest of the new systems is expected to run at a peak speed of 20 trillion mathematical operations per second, and will do so in the NAVOCEANO environment where operational resilience and high availability are of paramount importance. Typical operational availability of the systems is expected to be over 99%.

The NAVOCEANO supercomputing solution consists of IBM eServer p655 systems connected together with IBM’s clustering technology. Each of the new HPC systems is based on POWER4+ microprocessors and utilizes the AIX operating system environment.

Having been termed the first ‘server on a chip’, IBM continues to invest in the POWER architecture to offer customers open, innovative technology solutions through AIX, OS/400 or Linux operating systems that complement the growing demand for 64-bit applications. IBM’s family of POWER microprocessors is among the most widely used in the industry. In addition to being the force behind IBM’s pSeries, iSeries and JS20 BladeCenter servers, the microprocessor technology can be found in Nintendo game consoles, Apple computers, and some of the world’s most powerful supercomputers and storage systems.
