Linux at the forefront of Space Research with NASA.

One of the fastest Supercomputers was unveiled at Supercomputing 2004 in Pittsburgh last week. This is an exciting space to watch Linux grow. Everywhere you looked Linux was being used in various hardware configurations. The show rocked as it was a marriage of supercomputing solution providers and University research facilities to show what is being done with this computing power. You got to mingle with some scientists from all over the world and take a peek at their projects. Japan's 5,120-processor Earth Simulator was pretty cool, there was lots to see.

The Columbia Supercomputer named to honor the crew of the Space Shuttle Columbia lost Feb 1, 2003 is an integrated cluster of 20 interconnected SGI Altix 512-processor systems. There are 10,240 Intel Itanium 2 processors and delivers sustained performance of 51.87 trillion calculations per second (teraflops) and peaks at 60.96 teraflops. This supercomputer is now ranked the second fastest on the TOP 500 list. The only one that is faster is Blue Gene, IBM's supercomputer at the USA Department of Energy's Lawrence Livermore National Laboratory.

This Supercomputer built in 120 days allows NASA to improve computational power to solve immediate issues like "Return to Flight" for the space shuttle. Hydrogen Gas flow chambers simulations for example in the Space Shuttle Propulsion systems can now be done in days instead of weeks. Other projects for the Columbia will include earth modeling, space science and aerospace vehicle design. Simulations of the evolution of the Earth and planetary ecosystems with high fidelity has been beyond the reach of Earth scientists for decades," said Ghassem Asrar, Deputy Associate Administrator of NASA's Science Mission Directorate. "With Columbia, scientists are already seeing dramatic improvements in the fidelity of simulations in such areas as global ocean circulation, prediction of large scale structures in the universe, and the physics of supernova detonations." Calculations that use to take years can now be done in days.

The SGI Altix 3700 Supercomputer is a performance breakthrough with open source computing. The hardware combines the cost effectiveness of clusters with the scalable performance and big data capabilities of a supercomputer. It offers large global shared memory for demanding HPC applications with big data sets between cluster nodes. Data transmission speed round trip can be as low as 50 nanoseconds. Each node can scale up to 256 processors with 3TB of memory. The hardware runs on industry standard 64 bit Linux environment. This supercomputer performance rating is 42.7 trillion calculations per second sustained performance on 16 of 20 systems and a 88% efficiency rating on the LINPACK benchmark.

NASA has not been the only company to use SGI's hardware , it can also be found at the University of Rochester, Ford Motor Company and at the French energy giant Total. The Altix supercomputer is ideal for the computational needs of structural mechanics, fluid dynamics and chemical and material sciences that require massive data sets.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
