10 Coolest Devices Running Linux (Updated!)

Posted by Fibonacci on August 10, 2008

As you all probably know Linux is not limited to just desktops. It’s far reaching, actually. Not that you’d have a Terminal app on it or anything, but you could. Some of you may have a mobile phone running Linux and you probably don’t even know it. The most popular phone in the world runs Unix. That’s right. The iPhone runs on Unix. Are there any other cool devices out there running on Linux or Unix? Of course there are:

Evolution of Internet powers massive particle physics grid – Network World

Brookhaven has about 1,200 multicore x86 servers dedicated to the LHC, along with disk and tape storage that holds seven petabytes of data. Ernst says Brookhaven will have to scale that storage up significantly by 2012, when he expects to be storing 13 petabytes of Large Hadron Collider data.

Worldwide, the LHC computing grid will be comprised of about 20,000 servers, primarily running the Linux operating system. Scientists at Tier-2 sites can access these servers remotely when running complex experiments based on LHC data, Pordes says. If scientists need a million CPU hours to run an experiment overnight, the distributed nature of the grid allows them to access that computing power from any part of the worldwide network, she says.

Debian Gnu/Linux executa intervenção cirúrgica num cão sem intervenção humana

Esta notícia já tem uns dias mas não deixa de ser interessante, mais uma vez a minha distro favorita aparece nas notícias.

O Lonestar, o supercomputador do Texas Advanced Computing Center em Austin, efectuou uma intervenção cirúrgica a LASER, num cachorro, para tratamento de cancro, sem a intervenção de qualquer cirurgião.

TACC > TACC supercomputer performs laser cancer surgery on canine

“We had a fifteen minute window in which a million things had to go right for this treatment to be successful,” explained David Fuentes, a post-doctoral student at The University of Texas at Austin’s Institute for Computational Engineering and Sciences (ICES), and the central developer of the project. “There had to be no flaw, no silly bug, everything had to go perfectly. And if that wasn’t complicated enough, you add the complexity of a living animal. This is a pretty formidable problem.”

And yet, in April 2008, when the researchers performed the first full run of the system on a canine subject, the coordination went off without a hitch, proving the potential of supercomputers for patient-specific treatments and blazing a path to next-generation cyber-surgical methods.

The laser cancer treatment project uses the massive parallel processing power of supercomputers like Lonestar to perform real-time, patient-specific surgery remotely, in a way that responds to data-intensive monitoring methods. Using precise lasers, state-of-the-art thermal imaging technology, and computational methods that synthesize complex information in a fraction of a second, dynamic, data-driven laser treatments are being pursued as a minimally invasive alternative to the standard treatment of cancer.

Dell Duo-Core Linux Cluster User Guide

The configuration and features for the compute nodes, interconnect and I/O systems are described below, and summarized in Tables 1-3. The Rocks 4.1 cluster toolkit is used to manage the system.

# Compute Nodes: A node consists of a Dell PowerEdge 1955 blade running the a 2.6 x86_64 Linux kernel from kernel.org. Each node contains two Xeon Intel Duo-Core 64-bit processors (4 cores in all) on a single board, as an SMP unit. The Core frequency is 2.66GHz and supports 4 floating-point operations per clock period with a peak performance of 10.6 GFLOPS/core or 42.6GFLOPS/node. Each node contains 8GB of memory. The memory subsystem has an 1333 MHz Front Side Bus, and dual channels with 533 MHz Fully Buffered DIMMS. Both processors share access to the memory controllers in the memory controller hub (HCM or North Bridge).

RoadRunner o novo nº1 no TOP dos Supercomputadores – Powered by Cell and AMD using GNU/Linux

Temos um novo nº 1 na batalha pelo processamento, o novo RoadRunner concebido pela IBM com recurso ao CPU Cell usado na PS3 e aos CPU’s da AMD, consegue destronar o BlueGene/L do Lawrence Livermore National Laboratory, também ele construído pela IBM.

Para conseguir o feito, desta vez a IBM usou “12,240 Cell chips and 6,562 dual-core AMD Opteron processors in IBM QS22 blade servers”, por forma a conseguir obter um poder de cálculo de “RoadRunner, was benchmarked at 1.026 petaflops (a petaflop is equal to one thousand trillion calculations per second), making it more than twice as fast as the top-ranked computer in the previous version of the ranking.”

IBM Roadrunner – Wikipédia, a enciclopédia livre

Roadrunner é o nome do supercomputador de nova geração desenvolvido no Laboratório Nacional de Los Alamos localizado no Novo México (Estados Unidos).
Actualmente o supercomputador mais rápido do mundo, o Roadrunner foi desenhado para alcançar um nível de performance de processamento de 1.7 petaflops, alcançando 1.026 o que foi alcançado em Junho de 2008,[1] e
para ser o primeiro sistema Linpack do mundo TOP500 a 1,0 petaflops. A IBM construiu este computador para o Departamento de Energia dos Estados Unidos da América. O Roadrunner tem um design híbrido constituído por 6,480 processadores dual core AMD Opteron e 12,960 IBM
PowerXCell 8i CPUs em TriBlades especialmente desenhadas, TriBlades, interligadas por Infiniband.

O Roadrunner usa o sistema operativo Red Hat Enterprise Linux e é gerido com xCAT. O computador mais poderoso do mundo, o Roadrunner ocupa aproximadamente 557 metros
quadrados. Ficou operacional em 2008.

O DOE planeia usar o computador para simular como os materiais nucleares envelhecem e se o envelhecimento do arsenal nuclear dos Estados Unidos é seguro e confiável. Este será utilizado em outros projectos e experiências de
análise científica, financeira, aeroespacial e na indústria do

PC World – Business Center: IBM’s Cell-based RoadRunner Supercomputer Is World’s Fastest

The arrival of RoadRunner in the ranking pushes the IBM BlueGene/L system at the Lawrence Livermore National Laboratory off the top spot that it has held since November 2004. That machine is now the second fastest in the world with a maximum performance of 478.2 teraflops. Another IBM system, Blue Gene/P, at the Argonne National Laboratory, is ranked third and a Sun SunBlade x6420 Ranger at the University of Texas in Austin is ranked fourth. Another U.S. government machine, a Cray XT4 Jaguar at the Oak Ridge National Laboratory is in fifth place.
